I installed my first heat pump about 8 years ago, and several more have followed since then. So I’ll admit to a certain bias, but I think it’s fully justified: When compared with traditional heating, ventilation, and air conditioning (HVAC) systems that use a furnace for heat and an air conditioner for cooling, heat pumps can offer significant energy savings that result in lower household bills. They also could be called heat exchangers because that’s effectively how a heat pump conditions a space.

By using a refrigerant and a compressor, the technology can extract heat from outside—even when it feels quite cool—and pump that warmth into your home. In summer, it can be switched over to provide effective air conditioning. Heat pumps also can help reduce humidity. Other models are specifically designed for household hot water or for pool heating. Dual-fuel systems, which combine an electric heat pump and natural gas furnace, also promise high energy efficiency but are highly complex and expensive.

This in-depth guide details key features of heat pumps, including types, capacity, and efficiency ratings, and includes some of the best heat pump options for home use. I researched more than three dozen products and curated this list of top picks based on customer satisfaction, product efficacy, and value. We did a deep dive into the specifications, features, and customer reviews to select these top-selling heat pumps in a variety of categories. When judging heat pump efficiency, two figures are used: the SEER and HSPF ratings; for a full discussion of these terms, please see the Efficiency Rating section after the descriptions of our top picks.

What to Consider When Choosing a Heat Pump

There are more details to consider beyond the different types of heat pumps. The following includes some of the most important heat pump features that are key to maximizing both performance and energy savings in different situations.

Types of Heat Pumps

Heat pumps can be divided into three main types: air source, split-ductless, and geothermal. While all types use the same basic principle of heat exchange to warm or cool a house, understanding their different strengths helps narrow the choices for the best heat pump for a particular home.

Air Source

Air source heat pumps sit outside the home and use an internal ducting system much like other HVAC systems that provide hot or cool air inside. When switching from an electric or gas furnace to a heat pump, parts of the existing installation can often be used.

An air-source heat pump also can provide hot water, but it’s important to note that it is a separate system. An air-source hot-water heat pump is not the same as a heating and cooling heat pump, so two systems are needed if buyers want both functions. They are very effective in mild and warm areas, but additional heating may be required where the temperature regularly drops below 25 degrees Fahrenheit.


Like air-source heat pumps, split-ductless systems (also called mini-splits) have a condenser unit outside paired with a wall-mounted air handler that has a fan inside similar to air conditioners. Usually the latter is fitted high up near the ceiling. A handheld remote control is used to change settings.

The ducting that causes some heat loss in other systems isn’t necessary, so installation is generally more straightforward. The ductless feature makes it popular for house additions when a house has been extended and the owners don’t want to modify the current HVAC system. The amount of square footage it can condition depends on the unit used, and several units might be necessary to cover an entire house.


The temperature underground remains constant below about 6 feet deep, regardless of the season. A geothermal heat pump takes advantage of this consistent warmth. Liquid-filled pipes—called a “loop”—are buried underground either horizontally or vertically. They pick up the underground temperature that is then pumped around the house.

Also called ground source heat pumps, geothermal heat pumps can be used in areas where other systems are less effective in winter. However, installation costs are high, and the ground space needed makes them unsuitable for smaller properties.


When looking at the main benefits of the best heat pump systems, the main purpose usually is serving as an energy-efficient alternative to furnace and air conditioner combinations for a home. However, there are other areas where heat pumps can provide a cost-effective solution. Fitting a split system to an extension may be less expensive and easier than stretching an existing HVAC beyond its intended specification.

If there is space, geothermal heat pumps are a great way to provide hot water. Small air-source heat pumps also can provide effective heating for outdoor pools. Although they are less efficient when it’s cold, it’s unlikely that an outdoor pool would be used then anyway.

Output Capacity 

Whether comparing a heat pump with other HVAC systems or looking at a more modest installation, both the heating and cooling potential of single units or expanded systems will be important. The standard measurement unit of heat is the BTU. The generally accepted standard is that for both comfortable warmth in winter and sufficient cool air in summer, a system should provide 20 BTUs per square foot per hour.

For example, a 500-square-foot space with 8-foot ceilings needs a heat pump rated for 10,000 BTUs. Not all manufacturers provide BTU information, some preferring to use tons to describe a heat pump’s output capacity. A ton is equal to 12,000 BTUs per hour.

HVAC Compatibility

A frequent consideration is whether a heat pump can be effectively combined with other heating, ventilation, and air conditioning systems. While a split-ductless heat pump is a good way to add heating and ventilation when a living space is expanded, the advice of an HVAC expert may be needed for a proper assessment of compatibility among systems.

However, there are more advanced hybrid systems that integrate traditional furnace-based HVAC with an electric heat pump. They use the heat pump when the outside air is warm enough to make sense economically and switch over to the furnace when the temperature drops. Installation is more complex, but the resulting fuel savings can make it worthwhile.

Efficiency Rating 

With home energy costs continually rising, any way to manage consumption and save money is helpful. Heat pumps are typically more efficient than traditional HVAC and air conditioning combinations helping shoppers reduce their carbon footprint and save money. A heat pump’s actual heating efficiency is rated in several ways, and it varies depending on the type. With all systems, higher numbers are better, though the best heat pumps in terms of energy efficiency also tend to cost more.

Most air-source and split-ductless models provide two ratings. For heating systems, this is a Heating Seasonal Performance Factor (HSPF). There is a minimum United States federal standard of 7.7 HSPF, but the American Council for an Energy-Efficient Economy (ACEEE) recommends 8.5 or greater. For cooling, the Seasonal Energy Efficiency Rating (SEER) is used. Again, the federal minimum is 14 SEER, though ACEEE recommends 15 or more.

Geothermal heat pump efficiency is rated by the Coefficient of Performance (COP) for heating and Energy Efficiency Rating (EER) for cooling. Respective minimums are 3.1 for COP and 17.1 for EER.

Noise Level 

The amount of noise that a heat pump generates varies based on the type of heat pump. Air-source and split-ductless heat pumps both have an outdoor fan and compressor. While not aggressively loud like a chainsaw, they can create a constant background hum. The pitch will often rise as the energy demand increases.

Many air-source or split-ductless units are under 60 decibels, which is much like normal conversation. However, some exceed 70 decibels, which is comparable to traffic noise or a vacuum cleaner. As they’re frequently sited on or near an outside wall, the noise level likely has a significant impact on where the unit is positioned. The indoor fan for split-ductless heat pumps is usually very quiet and unlikely to cause noise problems, even in bedrooms.

Geothermal heat pumps have no external fan. As a result, many are almost silent and frequently described as “whisper quiet.”


Installation is a very important consideration because professional installation is strongly recommended with many heat pumps.

A split-ductless heat pump is the easiest type to install, but even with good DIY skills, it will take time and patience. As a rough guide, contractors often work in pairs and would expect installation to take around 5 hours.

Air-source heat pumps for pool heating can be self-installed, if you have the required electrical knowledge. Household systems are far more complex, typically requiring a couple of days to install. Unless you have a wealth of experience, it’s a job that’s probably best left to professionals. Several manufacturers warn that their equipment should only be installed by qualified technicians.

That’s also true with geothermal heat pumps. An initial survey is conducted to see if the site is suitable, then there’s substantial groundwork or drilling to install the loop. They are often recommended as an efficient solution for new builds and large open plots. Installation in well-developed urban areas can be challenging.


Now that you’ve had the opportunity to read about some of the key features and consider some of the best heat pumps on the market, you may have lingering questions. It’s a complex area, so it would be understandable if a few questions remained. The following answers to some of the most common queries may help.

Q. What are heat pumps?

A heat pump is a low-energy way of providing both heating and cooling. It can be used for the whole house or a single room and to provide hot water or heat your pool.

Q. Do heat pumps use a lot of electricity?

Heat pumps typically output three to four times more energy than they consume, so they use electricity very efficiently. This also helps reduce the use of fossil fuels when compared to traditional alternatives. As with any heating or cooling system, heat pumps need proper management to maximize savings.

Q. How do I choose the best heat pump for my home?

To choose the best heat pump, investigate how efficiently it heats and cools a given space, plus the cost and the ease of installation. These and other key considerations are covered in detail above.

Q. Should I turn off my heat pump in extreme cold?

Air-source and split-ductless heat pumps can be damaged if they freeze, but many have internal heaters to prevent this. It’s important to check. Properly installed geothermal heat pumps should not be affected because they are deep enough that the cold does not reach them.

Q. How long do heat pumps last?

Heat pump longevity is based on the type. Air-source and split-ductless last an average of 15 years, though it is not uncommon for them to last more than 20 years. The indoor unit of a geothermal heat pump can be expected to last 25 years or more, with 50 years usually quoted for the underground loop.

Q. What is the best heat pump brand?

While selecting the best heat pump should be based more on specification than brand, Daikin, Goodman, and Pioneer all perform consistently well in independent satisfaction surveys.

Q. What is the most efficient heat pump on the market?

Two are difficult to separate. The top pick, the Pioneer wall-mount heat pump, is an outstanding device. The Cooper & Hunter heat pump is equally efficient.
