How Heat Pumps Work and What they Cost

Depending on your location, unit size and type, installation costs typically range from $8,000-25,000. While this initial investment may seem high, the long-term savings on energy bills can offset the expense. This is for the cost of the unit- there are additional costs to distribute the conditioned air.

These are great appliances for homeowners because they eliminate the need to purchase and install both a furnace for heating and an air conditioner for cooling. It does both. In colder regions the device may need to be a “hyper heat pump” which can shoulder the extra swing in temperature.

Heat pumps can run on gas, electricity or solar, depending on the type and your specific energy needs. These appliances can struggle with frigid temperatures, so are more common in parts of the country with moderate climates.

The basic components of a heat pump include an evaporator, compressor, condenser, and expansion valve. If you have ever held a spray paint can and pressed the nozzle for a while, then you felt the temperature get colder. That change of states from liquid to gas is the cooling cycle. This principal, in turn can deliver the conditioned air for distribution into a ducted system or ductless system.

Types of Heat Pumps

There are three main types of heat pumps:

Air-Source Heat Pumps (ASHPs): These are the most common type and work by transferring heat between the indoor air and the outside air. They are relatively easy to install and are suitable for most climates, although their efficiency decreases in extremely cold temperatures.
Ground-Source (Geothermal) Heat Pumps (GSHPs): These systems transfer heat between the indoor air and the ground. Because the ground maintains a relatively constant temperature throughout the year, geothermal heat pumps are more efficient than air-source systems, especially in regions with extreme temperatures. However, they require more significant installation work and higher upfront costs.
Water-Source Heat Pumps: These systems exchange heat between indoor air and a water source, such as a lake, river, or well. They are less common but can be highly efficient in specific applications, particularly where a water source is readily available. Understanding heat pump types can save you money and headaches.

Primary benefits of Heat Pumps

Heat pumps offer several advantages over traditional heating and cooling systems:

Energy Efficiency: One of the most significant benefits of heat pumps is their energy efficiency. Because they transfer heat rather than generate it, heat pumps can achieve efficiencies of 200-400%. This means they can produce two to four times more energy than they consume, leading to lower energy bills.
Environmental Impact: By reducing the need for fossil fuels, heat pumps can significantly lower greenhouse gas emissions. This makes them an environmentally friendly option, particularly when combined with renewable energy sources like solar or wind power.
Dual Functionality: Heat pumps can provide both heating and cooling, eliminating the need for separate systems. This not only saves space but also reduces the installation and maintenance costs associated with managing two different systems.
Comfort: Heat pumps provide consistent and even heating, reducing the temperature fluctuations that can occur with other systems. They also dehumidify the air while cooling, improving indoor air quality and comfort.
Long Lifespan: Heat pumps are durable and have a long lifespan, often lasting 15 to 25 years with proper maintenance. This longevity makes them a sound investment, especially considering the energy savings they provide over time.
Incentives and Rebates: Many governments offer incentives and rebates to encourage the adoption of heat pumps. These financial incentives can help offset the initial installation costs, making heat pumps a more accessible option for homeowners and businesses.
