I started installing heat pumps around 11 years ago and have developed a certain bias toward them. 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 results in lower household energy bills.
Heat pumps are sometimes also called heat exchangers because that’s effectively how they condition a space. Home heat pumps use a refrigerant and a compressor to extract heat from outside—even when it feels quite cool—and pump that warmth into your home. In the summer, they provide effective air conditioning and help reduce humidity. Other types of heat pumps are specifically designed for household hot water or pool heating.
To compile this in-depth heat pump guide, I researched more than three dozen products to curate a list of top picks based on customer satisfaction, product efficacy, and value. I also did a deep dive into heat pump types, capacities, and efficiency ratings before choosing the Senville 24,000-BTU Mini-Split Heat Pump as my top pick for its efficiency, powerful output, and quiet operation. For some circumstances, however, another model may be a better option. Keep reading for a full breakdown of 10 of the best heat pumps on the market.

How We Chose the Best Heat Pumps
I have personally bought heat pumps from several leading manufacturers, so I have my own preferences. However, to ensure a balanced report, I worked with the Bob Vila team and researched the best heat pump systems in a variety of categories. The resulting list factors in heating power, coverage, noise level, heating and cooling functions, and special features offered by the top heat pump brands. We also focused on models with high customer satisfaction when looking at the most efficient way to heat a home.
The heat pumps on the list offer 12,000 to 36,000 British thermal units (BTUs) of heating power, with the exception of the pool pump. These units heat spaces from 258.33 to 1,500 square feet to accommodate different user needs and spaces. They also have low operating volumes and work as both heating and cooling systems. We also considered units with special features like Wi-Fi controllability, remote controls, and smart-home integration.
What to Consider When Choosing a Heat Pump
Beyond the common types of heat pumps, there are more details to consider. The following includes some of the most important heat pump features that maximize performance and energy savings, helping you avoid common home heating mistakes.
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 space, understanding their different strengths helps narrow the choices for the best heat pump for a particular home. Depending on where you live, different types of heat pumps may also be eligible for tax credits.
Air Source
Air source heat pumps sit outside the home and use an internal ducting system, much like other outdoor HVAC systems that provide hot or cool air inside. If you’re switching from an electric or gas furnace to a heat pump, it’s likely you can use part of the existing furnace for installation.
An air-source heat pump can also provide hot water, but it’s important to note that an air-source heat pump water heater is not the same as a heating and cooling heat pump, so two systems are needed if buyers want both functions. (See our picks for the best heat pump water heaters here.) They are very effective in mild and warm areas, but additional heating may be required where the temperature regularly drops below 25 degrees Fahrenheit. For this reason, an air-source model is not the best choice for a cold-weather heat pump.
Split-Ductless
Like air-source heat pumps and traditional air conditioners, split-ductless systems (also called mini-splits) have a condenser unit outside paired with a wall-mounted air handler and fan inside. The interior portion is typically fitted high on a wall near the ceiling, requiring the use of a handheld remote control to change settings.
The ducting that causes some heat loss in other systems isn’t necessary, so installation is generally more straightforward. Ductless units are popular for house additions where 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.
Geothermal
The temperature underground remains constant below about 6 feet deep, regardless of the season. A geothermal heat pump takes advantage of this consistent warmth using liquid-filled pipes—called a “loop”—buried underground. These pipes pick up the underground temperature and pump it 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, in addition to the price of a heat pump, installation costs are also high, and the ground space needed makes them unsuitable for smaller properties.
Purpose
The main purpose of an a/c heat pump system is usually to serve as an energy-efficient alternative to furnace and air conditioner combinations. 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 can also provide effective heating for outdoor pools, though they are less efficient when it’s cold (when an outdoor pool is less likely to be used anyway).
Output Capacity
Whether comparing a heat pump with other HVAC systems or considering a more modest installation, the heating and cooling potential of single units or expanded systems is important. The standard measurement unit of heat is the BTU (British thermal unit), and a system should provide 20 BTUs per square foot per hour for both comfortable warmth in winter and sufficient cool air in summer.
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, however, as some prefer to use tons to describe a heat pump’s output capacity. A ton is equal to 12,000 BTUs per hour.
HVAC Compatibility
Some heat pump buyers may need to consider whether the pump they’re considering 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 installation expert may be needed for a proper assessment of compatibility among systems.
Another option is to consider advanced hybrid systems that integrate traditional furnace-based HVAC with an electric heat pump. These systems use the heat pump when the outside air is warm enough to make sense economically and switch to the furnace when the temperature drops. Hybrid heat pump installation is more complex, but potential fuel savings can make it worthwhile.
Efficiency Rating
With home energy costs continually rising, any way to manage consumption and save money is worth investigating. Heat pumps are typically more efficient than traditional HVAC and air conditioning combinations for helping shoppers reduce their carbon footprint and save money.
Heat pump heating efficiency is rated in several ways and 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, this is a heating seasonal performance factor (HSPF). The minimum United States federal standard is 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. The federal SEER 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 a heat pump generates varies depending on the type. 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, 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
Installation is a very important consideration because professional installation is strongly recommended with many heat pumps.
Split-ductless heat pumps are the easiest to install, but doing so takes time and patience, even with good DIY skills. 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. Whole-house heat pumps 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 will need to be conducted to determine whether the site is suitable, and then substantial groundwork or drilling will be required to install the loop. These pumps are often recommended as efficient solutions for new builds and large open plots. Installation in well-developed urban areas can be challenging.
FAQs
Now that you’ve had the opportunity to read about some of the key features and consider some of the best models on the market, you may have lingering heat pump questions. The following answers to some of the most common queries may help.
Heat pumps typically output three to four times more energy than they consume, so they use electricity very efficiently. Heat pump use reduces fossil fuel consumption compared to traditional alternatives. As with any heating or cooling system, heat pumps need proper management to maximize savings.
Air-source and split-ductless heat pumps can be damaged if they freeze, but many have internal heaters to prevent this. Properly installed geothermal heat pumps should not be affected because they are deep enough that the cold does not reach them.
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.
As with HVAC brands and HVAC systems, selecting the best heat pump should be based more on specifications than brand. That said, Daikin, Goodman, and Pioneer all perform consistently well in independent satisfaction surveys.
The Senville tri-zone heat pump and Friedrich single-zone heat pump are the most efficient heat pumps on our list. The Pioneer Diamante is also quite efficient, but it is only suitable for small spaces.
The biggest downside to a heat pump is that installation can be difficult or costly. If you’re an experienced DIYer purchasing a pump with a comprehensive installation kit, you might be fine. Sometimes, however, installation requires electrical work that’s better left to a professional. Some heat pumps also require professional installation as part of their warranty requirements.
