Heat Pumps Buying Guide
What is a heat pump?
A heat pump is essentially an all-in-one air conditioning and heating system that works year-round to keep your living space comfortable. During the summer, it extracts heat from the inside of your home and moves it outside. During cooler months, the device reverses the process, collecting heat from the outdoor air and transferring it to the inside of your home.Even when it’s cold outside, there is still some heat in the air. A heat pump pulls this heat out of the air and transfers it into your home. If outside heat is insufficient, the heat pump has an electric heater that will supplement the outdoor air to meet your heating needs.
How to buy the best heat pump
A heat pump is a major investment, so you should carefully consider several factors before making a buying decision to ensure you get the most value from it. We cover these factors in the following sections.
Types of heat pumps
There are three main types of heat pumps: air source, split-ductless, and geothermal. All heat pumps operate on the same principles but gather heat from different sources. Regardless of the type, all heat pumps should be installed by a professional HVAC technician who can determine the right size and product for your home and climate.
Air source heat pump
Air source, also known as air-to-air, is the most popular type of heat pump. The system is comprised of an indoor and outdoor unit and works by extracting heat from the outdoor air and transferring it into the home. These heat pumps are inexpensive and take up little space. Since they use outside air as the medium for heat exchange, the units function well in moderate climates.
Split-ductless heat pump
Split-ductless heat pumps are also called mini-splits. They include two units: an outdoor compressor and a maximum of four indoor handlers. These systems do not require ductwork, circulating refrigerant through the tubing that connects the indoor and outdoor units. Split-ductless heat pumps are quiet, energy-efficient, and can be operated by remote control. They offer design flexibility and are ideal for homes without ducts.
Geothermal heat pump
Geothermal heat pumps are classified into ground and water source heat pumps. They move heat through a series of pipes that are buried in loops outdoors. In addition to controlling temperature, geothermal heat pumps also control humidity. These systems require little maintenance and work well in extreme climates.
Heat pump sub-types
In addition to the three main types of heat pumps, there are also several sub-types, including hybrid, solar, and absorption, or gas-fired, heat pumps.
Choose the right size
Size is a critical factor when considering heat pumps. Choosing the right size will help you avoid issues such as inflated energy costs, extreme temperature fluctuations, imbalance in indoor humidity, and short cycling of the system. A heat pump that is too small will work too hard to provide the amount of heat you need in your home, while one that is too big will emit too much heat, resulting in inefficiency.When it comes to size, it is more about the unit’s heating and cooling output than its physical bulk. Generally, heat pumps range from 1.2kW to over 10kW. Here are some factors to consider when choosing your heat pump’s size:
- Whether it will be used mainly for heating or cooling
- Your local climate, including the average seasonal high and low temperatures
- The level of insulation in your home
- The size of your living space and the number of people who live in it.
Compare heat pump’s cost
Factors that affect the cost of a heat pump include the brand and quality, size and output, efficiency, and type of unit. Installation and placement also affect the final cost. On average, it costs about $5,600 to install a heat pump. For precise pricing information, including installation costs, you should contact a local HVAC professional.
Read heat pumps reviews
Before buying a heat pump, it’s helpful to research reviews. Reviews give you insight into the pros and cons of a specific unit and how it compares to other units within its range. When going through reviews, focus on performance, temperature range, energy-efficiency, sound ratings, cost, features, reliability, and warranties.

There are a few different ways to install heat pump systems. To ensure optimum comfort, you should consider hiring a professional to install it for you.
- Split system: This is the most common installation of any ductless heat pump. An indoor evaporative unit is placed in the attic, basement, or closet, while the condenser and compressor unit is located outside in a large metal box.
- Package system: With this type of installation, all the mechanical components are housed in a large metal box outside. Only the ductwork is found inside the home.
- Mini-split system: Also known as a ductless heat pump system, this system is great for homes without ducts. The system works much like air source heat pumps but on a smaller scale.
Window heat pumps are ideal for homeowners who want to manage indoor temperatures without spending too much on energy bills.
Heat pump brands
Before we review some of the top heat pump brands on the market, here are some key industry definitions:
- AFUE Rating: The AFUE (Annualized Fuel Utilization Efficiency) rating is a measure of how efficiently a unit uses fuel. The higher the rating, the more efficient a unit is.
- SEER and EER Ratings: The SEER rating (Seasonal Energy Efficiency Ratio) is calculated by dividing the cooling output of the unit in a given season by the energy it used during that period. EER is a measure of a unit’s efficiency when outdoor temperatures are at 95 degrees Fahrenheit.
- BTU: BTU stands for British Thermal Unit, which measures the amount of heat energy needed to raise one pound of water to one degree Fahrenheit at sea level. The higher the BTU, the faster the unit can cool a space.
- HSPF: HSPF (Heat Season Performance Factor) is a measure of a heat pump’s efficiency. It measures the total heating output in BTU compared to the total energy used in watts. The higher the HSPF, the more efficient the heat pump.
