11 Heat Pump Myths and Facts : Overview

Are you looking for a new heating and cooling system but don’t know if a heat pump is right for you? Read on! We want to dispel some of the misinformation and address eleven common myths to give you the real facts.

Some heat pump myths include them being too costly or ineffective, or perhaps too noisy. However, with state rebates, improvements in technology, and other positives listed below, you’ll find that these are simply false.

Heat pumps have many benefits over other heating and cooling systems. Their name may be misleading because they do, in fact, also provide cooling in addition to heating. Read the following heat pump facts to learn more about their advantages and what to know about heat pumps.

The myth that heat pumps don’t work in cold weather is false. While their efficiency decreases, modern heat pumps, especially cold-climate models, are designed to provide effective heating even in harsh conditions, often outperforming traditional fossil fuel systems.

Heat pumps traditionally work by extracting heat from the outside air and transferring it indoors, which is easier in warmer climates. But with improvements, modern heat pumps are engineered to maintain high performance even at temperatures well below freezing.

If you live in a cooler area, take care to look into heat pumps for cold climates. For areas with harsh winters, dual-fuel systems, which combine a heat pump with a backup heating system (like a gas furnace), can provide reliable and efficient heating during extreme cold snaps.

It’s a common misconception that heat pumps only provide heating. They are versatile systems that can both heat and cool by transferring heat, acting like a refrigerator in reverse for heating in winter and cooling in summer using a reversing valve.

In winter, heat pumps extract heat from the cold outdoor air (even in freezing temperatures) and transfer it indoors, warming the house. In summer, the process reverses, taking heat from inside and releasing it outside, cooling the home.

Modern heat pumps, especially compared to older models, are generally no louder than other HVAC systems like air conditioners or furnaces, producing a low hum around 40 to 60 decibels (dB), comparable to a refrigerator. Heat pumps, like air conditioners, use fans and compressors that generate some noise.

Ultra-quiet models can achieve lower sound ratings. Outside air-source heat pumps can produce a low hum, but this is often less noticeable than an indoor furnace. Ground-source heat pumps are generally even quieter. Several factors can affect the heat pump noise levels including model, installation, location, and maintenance.

Look for low-noise models or noise-canceling features, such as discharge mufflers or insulated compressors.

Using a professional HVAC installer can also help with noise reduction strategies.

While heat pumps can seem expensive upfront, their high energy efficiency and potential for long-term savings make them a smart investment. Federal tax credits and state rebates can help offset installation costs.

Heat pumps are more energy-efficient than traditional heating and cooling systems because they transfer heat rather than generate it, requiring less operating energy. By reducing reliance on fossil fuels, you also reduce your carbon footprint. By using less energy, heat pumps can lead to substantial savings on utility bills.

Homeowners can claim a federal tax credit of up to 30% of the cost of buying and installing a heat pump, with a maximum credit of $2,000 per year. Many states offer additional rebates and incentives to further reduce the cost of installation. California offers a statewide rebate of $1,000 per household, up to two systems, to help offset the cost.

Many utility companies in California offer additional rebates for heat pumps, ranging from $100 to $3,000. Some programs prioritize low- and moderate-income households, offering higher rebates to make heat pumps more accessible.

You can often combine federal tax credits with state rebates and utility incentives to maximize savings.

Another heat pump myth is that they are too large and space-consuming. While heat pumps do need space for installation, especially for outdoor units, they often take up less space than traditional heating and cooling systems, and there are compact options available.

A qualified HVAC professional can help determine the best location and size for your heat pump system, considering the difference sizes between an air-source, ground-source, and air-to-air heat pumps. Take into account both the outdoor and indoor components.

Simply put, heat pumps do not require more frequent servicing than other HVAC systems. With proper maintenance, they can be reliable and efficient. Regular maintenance twice a year (spring and fall), is crucial for optimal performance and longevity.

A well-maintained heat pump operates more efficiently, prevents major breakdowns, and extends the lifespan. Addressing minor issues during routine servicing can prevent them from escalating into expensive repairs.

A clean and well-tuned heat pump uses less energy, saving money on utility bills. Regular maintenance by a heat pump repair service ensures your heat pump provides comfortable indoor temperatures in all seasons.

While heat pumps are efficient at transferring heat, they don’t always run non-stop, and their efficiency can vary based on outdoor temperature and system design.

Heat pumps transfer heat, rather than generate it, using a refrigerant cycle, as mentioned above. Instead of running continuously, they cycle on and off, depending on the temperature difference inside and outside.

As temperatures drop, heat pumps may require more energy to transfer heat, but they can still be more efficient than traditional heating systems. Some heat pumps have backup electric coils or furnaces that can kick in during extremely cold temperatures to maintain comfort.

Heat pumps use electricity to operate, and as more electricity is generated from renewable sources, the reliance on fossil fuels for heating decreases.

This shift towards cleaner energy sources is crucial for reducing greenhouse gas emissions, and reduced reliance on fossil fuels will also lower your carbon footprint. Heat pumps do not involve the combustion of fossil fuels, which means they do not release harmful pollutants into the air. This can lead to better indoor air quality and a healthier living environment.

Heat pumps have a smaller footprint than traditional HVAC systems, meaning less disruption to landscaping and a more discreet solution for heating and cooling.

The myth that heat pumps require extremely well-insulated homes to function is false, but insulation significantly impacts efficiency.

Having a well-insulated home minimizes heat loss, allowing the heat pump to operate more efficiently and potentially use a smaller unit. In contrast, a poorly insulated home will require a larger, more powerful unit to maintain comfort, increasing costs.

However, heat pumps can still provide energy savings even with poor insulation, as the efficiency gains are significant compared to gas boilers. So while good insulation is beneficial for heat pump performance, it’s not a prerequisite.

Both ducted and ductless systems have their own advantages and disadvantages depending on the specific needs and circumstances of a home or building.

The advantages of ducted heat pumps include more consistent temperatures, quieter operation, sleek design, and more cost savings long term.

Some disadvantages include energy loss, especially if they are long or poorly insulated, complex installation, and higher upfront costs.

However, ductless heat pumps (mini-splits) also have their own considerations. Increased energy-efficiency, zoned heating or cooling (such as in an individual room), easier installation, and lower installation costs are some advantages of choosing ductless.

On the flip side, you can have the disadvantages of less consistent temperatures, noisier operation, aesthetic concerns, and higher installation costs if multiple units are required.

The idea that heat pumps cost more than other HVAC options is partially true in terms of initial installation, but often untrue in terms of long-term operational costs and overall savings. Converting to an all-electric system can also have higher installation costs.

However, government incentives and rebates, like those offered through the Inflation Reduction Act, can help offset these costs. Going with a dual-fuel system or a plug-and-play air handler can also help offset the cost of converting to an all-electric system. Higher energy efficiency than traditional systems translates to lower energy bills in the long run. Heat pumps also tend to have lower maintenance costs compared to combustion-based systems.

Heat pumps offer the benefit of both heating and cooling in one unit, saving money on the cost of two separate systems.
