There’s Still Plenty of Time to Get Tax Credits on Geothermal Heat Pumps

While many of the federal tax incentives for energy-efficient residential HVAC systems expired a couple of years ago, the tax credit for geothermal heat pumps (and home solar systems) remains in effect through 2016. This means homeowners still have a year to write off a big part of their investment for this super-efficient technology, the geothermal heat pump.

How Does a Geothermal System Work?

Geothermal systems start with a network of pipes buried on your property, or submerged in a body of water. The ground system can either be a shallow horizontal loop field or a very deep vertical loop field, depending on what sort of lot your house is built on, among other factors. A liquid solution — usually a mixture of antifreeze and water — serves as the medium of heat exchange.For heating, the solution circulates in the pipes, extracting heat from the ground, which is a moderate 50-60 degrees. The heat energy is transferred from the water solution to a heat pump unit inside the house, and then transferred into indoor air, which is distributed via a blower fan and ducts, just as with any heat pump system. Cooling with a geothermal heat pump works the same way, except that heat energy extracted from the house is transferred to the water-antifreeze solution, and then "rejected" into the ground.

Why is this So Efficient?

The energy used in a standard air-source heat pump is mainly used to extract heat energy from cold air for heating, or to release heat energy into very warm air for cooling. When the heat is being released from, or deposited into, ground or water that's neither hot nor cold, much less energy is required. This is what happens with a geothermal heat pump.

How Do the Tax Credits Work?

The energy-efficiency federal tax credit equals 30 percent of the cost of purchasing and installing an Energy Star-qualified geothermal heat pump in your home or second residence (not rentals).

Five Things You Need to Know About Heat Pumps

Heat pumps are a highly versatile climate control option for just about any home, offering excellent performance as well as tremendous savings. But before you decide to buy one, consider a few things you should know:

1. There are actually two types of heat pumps. Heat pumps can be divided into air-source and ground-source variants.

   • An air source heat pump uses outdoor air to gather latent heat during the heating season and release latent heat during the cooling season.

   • A ground-source heat pump, on the other hand, draws its latent heat from below-ground water sources. It also sends latent heat underground during the cooling season.

2. They use refrigerant to cool and heat your home. The average air conditioner uses its refrigerant as a medium for collecting latent heat found within indoor air and expelling that heat outdoors. A heat pump follows the same principle during the cooling season, but it completely reverses the process during the heating season, when it uses its refrigerant to draw latent heat from the outdoor air instead.

3. They can be used with supplementary heat sources. Most heat pumps are designed to be paired with electric, gas, or even oil heat. This can give you an effective fallback if you need a little extra heat during the winter.

4. Having one installed in your home can help save you money. A typical heat pump is designed to use far less energy for heating and cooling than other types of HVAC systems. An Energy Star-qualified system can save you even more money, as these units use up to 20 percent less energy than standard models.

5. Buying one can qualify you for a tax credit. Purchasing a ground-source heat pump can qualify you for a federal tax credit toward 30 percent of your system’s total cost.

The Importance of Sizing a Geothermal Heat Pump

A geothermal heat pump is an inexpensive, renewable way of heating and cooling your home by using energy from the ground. However, before you invest in a geothermal system, it's important to get the correct size for your space. Otherwise, you could end up wasting energy instead of saving it. Let's look at why sizing a geothermal heat pump is so important, and how to do it properly.

How a Geothermal System Works

No matter what the weather is like outside, the temperature about 10 feet underground is a constant 50 to 60 degrees. A geothermal system buries a loop of pipe beneath the ground, then circulates liquid through it to absorb that heat energy and bring it into the home. During the summer, a geothermal heat pump extracts heat energy from indoor air and uses the ground as a heat-sink to dispose of the unwanted heat. The cool air is the result of this heat extraction.

Problems With Improper Sizing

If you size your system too small, it won't have the capacity to heat or cool the air as it should. It has to work harder to do the job properly, using extra electricity and putting undue stress on system components, which can cause unnecessary damage and ultimately shorten system life.Sizing a geothermal heat pump too large causes problems as well. A system that's too big will cycle on and off too frequently, which also causes damage and uses excess electricity. It also creates a disparity in temperature from one area to the next and can fail to dehumidify the space, making things wet and clammy.

So what size should your geothermal system be? It depends on the size of your home, as well as climate, soil type and other factors. Talk to a professional HVAC contractor, who can measure these factors and make sure your geothermal system and piping loop are the proper size for your home.

Get a Federal Tax Credit for Installing a Geothermal Heat Pump

A geothermal heat pump is the most energy efficient and durable system you can use in your home and a federal tax credit exists to help you offset the higher cost of these systems. A heat pump cools and heats by moving heat from one place to another. While air-source heat pumps depend on outdoor temperatures to harvest or deposit heat, a geothermal system executes this process by using underground resources.

Since temperatures vary little underground throughout the year, the geothermal system is more efficient at both heating and cooling. They use a loop field that's buried deeply underground as the resource for depositing heat in the summer and the resource in the winter. It's the loop field that adds the extra cost to a geothermal heat pump, and the tax credits will help offset this expense.

Homeowners who install a qualifying system can deduct its entire cost, with some exceptions, to receive a 30 percent credit on federal taxes. This credit applies to primary and secondary homes, but not rental properties. It even applies to new home construction. The program is so generous because geothermal systems have a low carbon footprint. The loop field can last 50 years or more, and the heat pump itself may last 25 years.

The federal tax credit won't cover the cost of the ductwork or a backup heating coil, but it will cover the cost of the desuperheater, an upgrade that takes the heat from your home and uses it to heat your water.

A geothermal system must meet the requirements for the Energy Star program to qualify and it must be installed on or before December 31, 2016. You can deduct the entire cost of the system, except for the ductwork and heating coil, to receive the credit. There's no cap on the amount you can deduct for the loop field and the remaining heat pump and desuperheater if you opt for this upgrade.

Don't Fall for These Geothermal System Myths

Geothermal HVAC systems take advantage of the earth's subterranean temperature. Although atmospheric temperatures fluctuate because of seasonal weather conditions, underground temperatures are surprisingly consistent at a depth of four to six feet.

Even though underground heat pump systems have been used successfully for 60+ years, geothermal system myths still abound, including:

• Durability. One geothermal system myth is that these systems are not durable. However, the earth loops that form the underground pipe network are remarkably long-lived. They can last for 50 years and typically carry an equal warranty. Water is most commonly used in the pipe network, instead of refrigerant-filled pipes.

• Noise Level. Geothermal systems are not noisy, contrary to common belief. Because the outside configuration is buried underground, it produces no noise to disturb your neighbors. The part of the system that is located indoors runs quietly. Geothermal applications are often misunderstood as one-dimensional, such as only capable of heating your home. But systems also include cooling, and they can even be configured to handle multiple tasks such as heating your home, your water inside and outside in pools.

• Space Requirements. A prevailing geothermal system myth is that you need a large yard. But even small yards can accommodate the underground network. If you have a larger yard, a horizontal configuration works well, but if your yard is small, you can have a vertical geothermal system.

• Renewability. Another myth is that a geothermal system is not a renewable energy technology. The fact is that geothermal systems reduce up to four times the consumption load on the electric grid than photovoltaic and wind power add to it.

• Cost. Perhaps the most popular geothermal system myth is that these systems are cost prohibitive to install and maintain. Although water does circulate throughout the earth loops, it is a recirculating system so there's actually no continual water consumption. The initial installation cost, which is sometimes costly, is offset by tax incentives and the overall savings over the life of the system.

Your Geothermal Heat Pump: How Long Will It Last?

When considering the high cost of installing a geothermal heat pump in the Tulsa area, the fundamental question of the system's longevity and maintenance costs needs to be addressed. The answer is simple: geothermal installations last a long time, and they require less maintenance than comparable gas or electric systems.

The heart, and primary cost of the system is the geothermal loop. If you choose a horizontal system, your contractor needs to remove a considerable amount of topsoil during the installation. After digging through four to six feet of red Oklahoma dirt, durable plastic pipe is installed and your yard is reconditioned.

The piping in the geothermal loop is rated to last 25-50 years, so you'll likely never need to replace it. Vertical geothermal loops cost more, as a deep hole needs to be drilled. But, if you have sensitive landscaping or limited space it might be the option for you. Since it's buried underground, the ground loop rarely needs maintenance—the high-density polyethylene plastic tubing is fused together, and shouldn't leak. Unlike exterior air conditioners and heat pumps, the ground loop can't be damaged by the elements or stolen.

In your home, the old inefficient furnace is removed and replaced with a compact, durable geothermal heat pump. This unit uses your existing duct work to heat and cool your home. It needs some of the same preventive maintenance that a traditional heater needs, like changing the air filters, but geothermal heat pumps are rated to last 20 or more years when cared for correctly.

Although the entry cost is high, a geothermal system is a long-lasting solution to expensive energy and HVAC maintenance costs in Broken Arrow. There are also intangible benefits, like less noise and consistent, comfortable temperatures in your home.

If you have more questions about geothermal energy, or if you're ready to take the next step, Air Assurance in Broken Arrow can help.

What's Your Heat Pump's Balance Point?

What's Your Heat Pump's Balance Point?

Adjusting your thermostat and weatherizing your home are critical to maximize your heat pump's efficiency. A heat pump's balance point is the lowest limit at which the equipment can provide heating comfortably. Precisely determining your heat pump's point can be somewhat of a challenge. With the abundance of technical jargon and the scientific principles that are a part of determining the heat pump's balance point, this can seem like an elusive concept.The two major factors that play roles in determining the balance point are heating load and heating capacity. Heating load defines the difference between what your home's current temperature is and the temperature at which you desire to heat or cool it to. In other words, this term illustrates how much cooling or heating your home requires. In contrast, heating capacity is a metric that defines how much cooling or heating your heat pump can provide.Your heat pump system uses outdoor air as the thermal energy source to cool or heat your home. This means that a heat pump's heating capacity is dependent on outside temperatures. The scientific principles behind this are complex, but what you as a homeowner need to remember is that a heat pump's capacity increases as its heating load decreases and its capacity decreases as its heating load increases. The heat pump's balancing point is the point at which these two are equal, generally this is around 35 degrees Fahrenheit.This is important because if the outside temperature drops below your heat pump's balance point, your home will need a supplemental heating source to ensure that your heating load demands are met. Usually, this is by more expensive electric heat strips or a gas or propane furnace. Backup heat is often controlled by a two stage thermostat that switches on when the heat pump has ceased to be effective at heating your home. You can better improve your heat pump's effectiveness and lower its balancing point by properly weatherizing your home.To learn more about heat pump's an balancing points, contact your Oklahoma HVAC experts at Air Assurance Heating, Air Conditioning, Plumbing today.Normal0falsefalsefalseEN-USX-NONEX-NONE/* Style Definitions */table.MsoNormalTable{mso-style-name:"Table Normal";mso-tstyle-rowband-size:0;mso-tstyle-colband-size:0;mso-style-noshow:yes;mso-style-priority:99;mso-style-parent:"";mso-padding-alt:0in 5.4pt 0in 5.4pt;mso-para-margin:0in;mso-para-margin-bottom:.0001pt;mso-pagination:widow-orphan;font-size:10.0pt;font-family:"Calibri","sans-serif";}

When Installing a Heat Pump, Let These Guidelines Show You the Way

When Installing a Heat Pump, Let These Guidelines Show You the Way

A heat pump is an economical way to keep your home cool in the summer and warm in the winter, especially in Midwestern climates. Instead of converting heat to fuel like combustion furnaces, heat pumps simply move heat. The performance of your heat pump relies on selecting the right type and size for your home and expert installation. Whether you use an air-source or geothermal heat pump, work with a professional HVAC technician to avoid problems and get the best results. When installing a heat pump, here are a few things to do first.

• Make sure your home is properly insulated with correct duct work and energy-efficient windows. If ducts are in the attic or crawl space, insulate with R-8 insulation to provide the best barrier. Install ducts inside your insulation to save energy. If your home is energy-efficient, you can install a smaller heat pump unit with shorter duct lengths.

• When installing new ducts, you can specify that measured air leaks should be below 10 percent of the airflow. A professional can reduce air leakage to below 5 percent with skill and careful planning and workmanship. Keep air leakage as low as possible for maximum efficiency.

• Do not use building cavities for your ducts. They typically leak, causing moisture problems, uncomfortable airflow and energy loss.

• After duct work is installed, test it by pulling on it to ensure that it's sealed well and fastened securely. Duct joints should be sealed with mastic.

• When installing a heat pump, put it on the north side of the house where it tends to be the shadiest. If this isn't possible, choose a shady place without any obstructions at least 10 feet from each open side and the top of your heat pump unit.

• For optimal heating and cooling efficiency, ask your technician or contractor to put a return register in each room of the house.

Your Air-Source Heat Pump Is Also for Cooling: How It Does a Good Job

Your Air-Source Heat Pump Is Also for Cooling: How It Does a Good Job

An air-source heat pump provides Broken Arrow homeowners efficient heating, but it also delivers efficient cooling and humidity management. If you’ve ever wondered how your heat pump does all these tasks season after season, keep reading to learn the basic technology involved, and you may discover a few tips to help maximize energy savings and home comfort.Air-source heat pump technologyAn air-source heat pump doesn’t produce heated or cooled air; it moves heat from one air source to another air source. These are the components of heat-pump technology.

• Evaporator and condenser: An air-source heat pump has two heat-exchanger coils. One is located inside your home (evaporator) and the other coil (condenser) is in a metal cabinet outside the home. Heat is absorbed and released, whether inside or outside your home, at the heat exchangers.

• Refrigerant: The refrigerant is the magic ingredient that moves heat from one heat exchanger to the other. For instance, in cooling mode, the refrigerant inside the evaporator coil absorbs heat from the air inside your home as the air circulates through the duct system. The refrigerant flows through copper tubing to the outside condenser where the heat is released.

• Compressor: The compressor is the heart of the heat-pump system. The compressor prepares the refrigerant for optimal heat exchange, and then pumps it to either the condenser or evaporator.

• Reversing valve: The reversing valve is the component that separates heat pumps from your typical air-conditioning system. The reversing valve changes the flow direction of the refrigerant, which allows for both heating and cooling. When the refrigerant leaves the compressor, it has been squeezed in preparation for heat release. The reversing valve sends the refrigerant to the appropriate coil to release the heat -- outside condenser for cooling mode and indoor evaporator for heating mode.

• Air filter: A quality air filter protects the coils and other components from debris accumulation and mold growth, which would hinder heat exchange. Check your air filter regularly to ensure peak performance.

Going Geothermal: Clean, Efficient Cooling for Tulsa's Hot Summers

Going Geothermal: Clean, Efficient Cooling for Tulsa's Hot Summers

Homeowners who strive for a high level of energy efficiency and longevity with their HVAC systems often choose geothermal heat pumps (GHPs). These systems top the list for both and provide all the cooling you need for Tulsa's long and hot summers. A GHP uses underground thermal energy to provide both cooling and heating by exchanging heat. In the summer, the GHP sends it underground, and in the winter, it removes the heat from the ground.A GHP consists of an underground loop field and an indoor air handler. Heat from the home is conveyed through refrigerant in the air coil to the underground loops, where the heat is absorbed by the earth. The compressor turns the refrigerant back into a liquid that is recirculated back to the air handler. It flows through the evaporator coil, and once again, picks up the excess heat in your home. The cycle continues until your home reaches the thermostat's setting.These systems offer much higher efficiency than standard air-source heat pumps or air conditioners because the temperatures underground are much cooler than the outdoor air and remain stable day and night. If you combine a desuperheater with the GHP, you can heat your water during the summer with the waste heat from your home.Besides conditioning bills that may be as much as 60 percent lower, your geothermal system lasts longer than conventional cooling systems. The loop field can last 50 years or more and the air handler 25 years with routine maintenance.These systems are so efficient and advantageous for homeowners that a federal tax credit exists to cover 30 percent of the cost and installation of qualifying systems. It's valid through the end of December 2016 and there's no upward limit on it.GHPs cost more than standard heat pumps or air conditioners, largely because of the loop field's installation, which varies based on the size of GHP you need, the yard's size, landscaping and soil conditions.If you'd like to learn more about a geothermal heat pump, contact Air Assurance.

The Heat Pump in Your Tulsa Home Needs Seasonal Maintenance

Most homeowners know that their heat pumps require seasonal maintenance. However, you may be neglecting to schedule the service, especially if you aren’t convinced it provides long-term value. Learn the tasks your heat pump technician will perform during a seasonal tune-up, and see just why investing in maintenance offers proven, long-term benefits.

Here are just some of the tasks your technician will perform during maintenance:

• Identify components that are wearing out, and replace parts as necessary.

• Check the ductwork, ensuring that the duct's joints don’t leak; install insulation around ducts located in the basement or attic.

• Test the system’s airflow, making adjustments as needed.

• Clean all the components like the coils, giving heat transfer a boost.

• Test the refrigerant charge, adding more refrigerant if the charge is below manufacturer’s specs.

• Clean electric terminals, tightening connections and lubricating the motor’s bearings.

• Calibrate the thermostat to ensure correct temperature readings.

• Check the control sequence, making sure that the heat pump’s heating mode is locked out when the thermostat is set to cool.

• Clean the condensate drain, identifying obstructions that lead to water damage.

These are the primary benefits the service affords:

• Lower operating costs -- With a seasonal check, the technician is able to keep all of the components in peak operating condition, so the unit performs efficiently. Over the years, you’ll pay less to operate the system than you would if you neglected to service it.

• Fewer repairs – A neglected system will eventually break down, and you’ll likely pay for costly repairs to get the heat pump running again. Preseason tune-ups allow the technician to identify worn components before they break down, which means you’ll pay for a part replacement only, which typically costs less.

• Better comfort – When you keep your system in good shape with regular maintenance, it will not only operate more efficiently, but it will be able to keep your home comfort at optimal levels, regardless of the outdoor conditions—or how hot it gets.

Air Assurance Heating, Air Conditioning & Plumbing has served homeowners in greater Broken Arrow for more than 30 years. Give us a call today to schedule preseason maintenance for your heat pump.

Heat Pump Too Frosty? Some Tips For Keeping It Ice-Free

It doesn’t take a snow storm to cause the heat pump condenser coil to ice over. Something as simple as a clogged air filter could be to blame. If you have problems with your coil accumulating ice, read through these causes for ice accumulation, and some troubleshooting tips to remedy the problem before you call in the pros. In heating mode, the refrigerant inside the outdoor condenser coil becomes extremely cold, while the refrigerant inside the indoor evaporator coil becomes extremely hot. This is heat exchange, and it’s the process that gives heat pumps up to 400 percent heating efficiency.However, when there is a glitch in the components which overburdens the system, efficiency and performance drop drastically, and the condenser coil ices over. These are some of the common issues for ice accumulation:

• Airflow is blocked or hindered by a clogged air filter, dirty condenser coil, malfunctioning air handler, and snow and/or other debris blocking airflow at the outside cabinet.

• Refrigerant charge is too high or low.

• Demand defrost mode isn’t functioning properly (bad timer, sensor or relay).

• Thermostat is faulty.

• Electrical contacts are worn.

• Air handler is malfunctioning or broken.

Except for specific electrical issues, or demand defrost malfunctions, all of these heat pump issues cause ice accumulation on the condenser coil by exerting too much stress on the system. Check all possible issues with hindered or blocked airflow. Ensure the outside cabinet has two or more feet of clearance on all sides. Check to see if the air handler is working.Significant issues, such as those involving faulty electrical components, thermostat or demand defrost malfunction, a sticky reversing valve or air handler issues, should be serviced by an HVAC professional. If after removing airflow obstructions, your heat pump still does not defrost properly, call your HVAC pro. Do not attempt to chip the ice away, or you may risk more serious damage.If you have any questions about your heat pump, or if you would like to schedule a service call, contact us at Air Assurance today.

Geothermal Heat Pump: Which Type Is Best For Your Tulsa-Area Home?

Heating and cooling your home can seem like a constant battle against nature.  But nature itself provides a sustainable source of temperate air right in your own backyard.About ten feet below ground, the temperature year-round is near-constant at about 54 degrees.  This is significantly cooler than the summer highs, and warmer than the winter lows.  One of the most eco-friendly heating and cooling systems available, a geothermal heat pump uses this phenomenon to reduce the work your heater and your air conditioner have to do.Geothermal heat pumps route air through buried pipes called ground loops, allowing the loops to balance their temperature with the earth below the frost line.  This gives the heating and cooling systems a big head start on their temperature adjustment, making for impressive efficiencies.  Because of their high efficiency and environmental friendliness, geothermal heat pump systems are eligible for hefty tax credits.The geothermal loop best suited for your home will take full advantage of available terrain features.  Different kinds of ground loops include:

• The horizontal loop. Often the best option for homes with large yard space, as the trenches are among the shallower holes that can be dug for the ground loop system. A certain amount of space is required for these, making them less suitable for small properties.

• Pond loops. A variation on horizontal loops, these take advantage of bodies of water such as ponds. This is only practical for bodies of water which meet certain depth and size standards, however.

• Vertical loops. Though they require much deeper trenches than horizontal loops, vertical loops have a much smaller horizontal footprint, making them more practical for small properties and densely-built areas.

• Open-loop and groundwater systems. Where there's an abundant supply of groundwater, this can be used as the heating/cooling fluid in place of air.

While this article can give you an idea of the options available, the best way to discover which geothermal heat pump system is right for your home is to talk to an expert.  If you'd like to learn more, feel free to contact us at Air Assurance.Our goal is to help educate our customers in the Tulsa and Broken Arrow, Oklahoma area about energy and home comfort issues (specific to HVAC systems). Image courtesy of Shutterstock

The Ductless Mini Split: All The Advantages Of A Heat Pump, And Then Some

When space for HVAC system installation is at a premium, but you still want all the benefits of a heat pump, consider installing a ductless mini split. These more compact heat pumps are just as powerful as a full-size system, but offer unique benefits all their own.

• Easier installation: Mini splits are easier to install because they don't need a large duct network for air distribution. While the outdoor unit of a ductless mini split is about the same size as that of a regular heat pump, the indoor components are much smaller in size and are not restricted by being connected to a duct system. Up to four indoor air handling units are connected to the outdoor unit via a conduit than runs through the wall. The conduit houses the power cables, refrigerant lines and the drain for the condenser.

• Freedom of placement: The indoor air handlers of the mini split can be placed almost anywhere in your home, limited only by the length of the connections to the outdoor unit. They can be arranged so that they don't interfere with room design or incorporated into a comfortable home environment.

• Flexibility for zoned heating and cooling: Each indoor unit operates independently of the other, providing a separate thermostat for individualized temperature control. This allows mini splits to be used where they are needed and wanted to provide zoned heating and cooling. Combine one or more in a particular area or spread them out as needed.

• Excellent efficiency: The lack of ductwork in a mini split means there is no chance of efficiency loss because of the air and energy leaks that can occur in ducted arrangements. This improves system efficiency and effectiveness, giving homeowners outstanding levels of home comfort at a lower cost--up to 30 percent less than traditional furnaces and air conditioners.

For more than 30 years, Air Assurance has brought expert HVAC sales, installation and service to customers in and around Tulsa and Broken Arrow.

The Geothermal Heat Pump: Still Eligible For That Hefty Tax Credit

Geothermal heat pumps are highly efficient heating and cooling systems that operate cleanly, quietly and economically. If you are considering installing a geothermal heat pump in your Tulsa-area home, remember there are still substantial energy tax credits available from the federal government that will help offset the cost of the system.By investing in geothermal heating and cooling, you are installing a home-comfort system that is astonishingly efficient, returning three or four units of heat for each unit of electricity the system consumes. This sounds like a physical impossibility, but it works because geothermal heat pumps move existing heat rather than burn fuel to generate it.Geothermal systems can slash energy costs by up to 70 percent. System prices vary based on factors such as the type of system and the features of the home where it is installed, but it is not uncommon for geothermal heat pump systems to cost between $10,000 and $20,000.In an effort to make geothermal heating and cooling more accessible, and at the same time promote energy conservation, the U.S. government offers a substantial income tax credit to homeowners who make the switch to geothermal. These credits can be applied directly to a homeowner's income taxes for the year in which the geothermal equipment was purchased and brought into service.Major points to keep in mind about the tax credits include:

• Credits amount to 30 percent of the system's cost, with no upper limit.

• System must be placed into service by Dec. 31, 2016.

• Credits apply to both the cost of the heat pump and the installation.

• Credits apply only to equipment for a primary residence or secondary home; rental units do not qualify.

• Credits are valid for geothermal systems purchased for either new or existing homes.

Federal tax credits expire in 2016.

There's No Need For Electricity When Using An Absorption Heat Pump

Conventional heat pumps are energy efficient but not energy free. A large proportion of electricity is utilized by the compressor to pressurize the refrigerant that’s the lifeblood of the heat pump system. The absorption heat pump, a new technology that requires no compressor and has been previously used in large commercial installations, is now finding its way into some residential applications. Absorption heat pumps deliver efficiencies in the range of 140 percent. Only the first stage of the absorption process, where a water/ammonia mixture is heated, requires an energy source such as natural gas or propane. Solar heating can also be utilized to heat the solution, as well as energy transfer from underground geothermal sources.The solution of water and ammonia is boiled into a vapor that duplicates the heat-exchange properties of refrigerant. As the ammonia vapor passes through the condenser coil, it condenses back to liquid, rapidly shedding heat into the air. When the heat pump’s in heating mode, the indoor coil is the condenser and heat shed by the coil warms the interior of the home. In cooling mode, the ammonia solution reverses and the outdoor coil disperses heat extracted from the interior into outside air.The pressurized liquid passes through an expansion valve that rapidly drops the pressure, converting the liquid into a frigid vapor as it enters the evaporator coil. In the evaporator, the vapor absorbs heat from air passing over the coil. In heating mode, the outside coil extracts heat from outdoor air; in cooling mode, the indoor coil takes the heat out of room air. The heat-loaded ammonia vapor then begins a re-absorption process where it is dissolved back into a weak solution of ammonia and water, then conveyed to the generator for heating, and the process repeats.With 27 years in the community and the largest full-service HVAC fleet in Tulsa, Air Assurance is your premier source for heating and cooling products and service.

Four Facts That Prove Heat Pumps Are A Viable HVAC Option

Tulsa ok - Heat Pump Energy-Saving Rebates

If you are curious about heat pumps, but don't know whether they are a viable option for your Tulsa-area home, we have a few facts that might pique your interest.

• They work for both heating and air conditioning. Heat pumps may deal with heat, as the name suggests, but that doesn't mean they are useful only during the winter. They can pump heat into your house, but they can also pump heat out of it. And removing heat from a house is actually how all air conditioning systems work, because "cold" is not a thing you can produce; "cold" is simply the absence of heat. So, one heat pump can replace both your furnace and air conditioner.

• They are the most energy-efficient way to both heat and cool a Green Country home. Because of how heat pumps work -- merely moving heat, rather than creating or destroying heat -- they use less energy than any other type of HVAC system. That means you'll be spending less on your utility bills year round.

• There is more than one type of heat pump to choose from. Some heat pumps exchange heat with the air outside your house, and are referred to as "air-source" systems. Others exchange heat with the ground, and are known as "ground-source" or "geothermal" systems. Air-source systems carry a lower upfront cost, whereas geothermal systems offer bigger energy savings to offset their higher installation costs. However, there are also different types of geothermal installations, and some are less expensive than others.

• They last a very long time. When we talk about the long-term savings offered by heat pump systems, we really mean long term. Ground-source heat pumps can last several years longer than comparable HVAC systems, and the parts of a geothermal system that are located below ground can last for over 40 years. So, even if it has a higher installation cost, a heat pump can end up saving you money through years of lower energy bills.

Heat Pump Maintenance -- What You Can Do And What To Save For A Professional

Heat Pump Maintenance -- What You Can Do And What To Save For A Professional

If you make heat pump maintenance a priority, you’ll maximize your investment in the system, ensure top energy savings and keep your home comfortable through every season.There are certain tasks homeowners can do, but others should be left to the professionals.Here’s what you can do:

• Check your filter every month or so, particularly when the heat pump is used on a regular basis, and change it when it looks dirty or dingy. This action will allow optimal airflow into the system and keep your indoor air cleaner.

• Inspect the coils on the outdoor unit when you inspect the air filter, and clean them with a soft cloth or use a garden hose (with a gentle spray).

• Keep the area around the outdoor unit clear, because debris like leaves and grass clippings can inhibit airflow.

• Check your home’s registers and grilles for dirt, and vacuum or wipe them down when dusty.

Here’s what an expert should do:

• Check the system for dirt buildup, and provide a comprehensive cleaning for components like the air handler and coils.

• Assess the ductwork’s performance, test the airflow, and seal any leaks.

• Test the system’s refrigerant charge, and look for leaks in the refrigerant lines.

• Check the electric terminals, clean dirty connections and tighten loose ones. Ensure that the nonconductive coating is at the appropriate levels.

• Inspect the motor, lubricating it to ensure smooth operations, and check the belt for wear and tear (on older systems).

• Assess the controls to ensure that the heat won’t cycle on when cooling mode is selected and vice versa.

• Ensure that the thermostat’s settings operate correctly.

• Conduct a comprehensive inspection of the reversing valve's operations.

If you perform these heat pump maintenance tasks every spring and fall, and schedule expert service in both seasons, you’ll ensure a top-performing system that lasts longer.

Are Heat Pumps A Good Choice For Homeowners In Tulsa and The Broken Arrow Region?

In the past, many people didn't consider a heat pump as a viable option for heating homes in the Tulsa and Broken Arrow region of Oklahoma. Winters can be cold and older heat pumps weren't as efficient at extracting enough heat from the air when temperatures dropped below freezing. New engineering advances in the technology have made these units an attractive option, even for people living where winters are typically cold. The average low in January, the coldest month in this part of Oklahoma, is 27 degrees with highs in the mid-40s, making a new heat pump an attractive option for heating and cooling. A modern heat pump can extract enough heat to warm a house, even at temperatures as cold as 25 degrees without needing auxiliary heating.Heat pumps use refrigerant to both heat and cool the home. When the appliance is set on heat, the extracted heat from the air is compressed, which superheats the refrigerant. The heated refrigerant goes into the air handler where the heat transfer coils sit. When the air handler blows over the coils, the air warms and blows through ductwork inside the home. In the summer, the heat pump reverses the cycle, taking the hot indoor air and losing the heat to the atmosphere.These units are among the most energy efficient to use since they extract heat from the air to either heat or cool the interior. A heat pump can provide 30,000 BTUs using 3.4 kW, while an electric heater using 3.4 kW provides just 11,560 BTUs. People living in climates even colder than Oklahoma have turned to heat pumps to heat during in the fall and spring. Some of the units have auxiliary heating elements that turn on when temperatures dip below 25 degrees and others have supplemental heating chambers that use gas, propane or oil.If you want to learn more about the heating and cooling advantages that a heat pump offers, contact Air Assurance.
