If you are looking for a convenient way to heat and cool your home or business, consider a heat pump.

Heat pumps efficiently heat in the winter and double as a cooling system in the summer while lowering greenhouse gas emissions. This clean technology is environmentally friendly, affordable to operate, and can last longer than other heating and cooling systems.

How Heat Pumps Work

Heat pumps are heating and cooling systems that move heat inside in the winter and draw heat outside in the summer. Instead of burning fossil fuels, they're powered by electricity to move - rather than create - heat and to keep your home or business at a comfortable temperature year-round.

Types of Heat Pumps

Mini-Split Heat Pumps

Mini-split heat pumps extract heat from the air outside and distribute it inside. During warmer months, this process is reversed to provide cooling. These highly efficient systems could cut your heating and cooling costs by up to 30 percent.

Mini-split heat pumps are a great option for homes and businesses without existing ductwork and for additions or rooms that always seem too hot or too cold. These systems can cost-effectively replace baseboard electric heating and window air conditioners, as well as displace oil and propane systems.

Central Heat Pumps

Central heat pumps operate the same way as a central air conditioning system, but are able to provide heating as well as cooling. These highly efficient systems provide a comprehensive heating and cooling solution—and can eliminate your reliance on fuel storage and the risk of running out of fuel.

Homes and businesses that have an efficient furnace and ductwork are great candidates for a central or ducted heat pump. Adding or improving insulation and air sealing around ductwork prior to installation will greatly improve system performance.

Ground Source Heat Pumps

Ground source (geothermal) heat pumps extract heat from the ground during cold weather, which is then distributed throughout your home or business. During warmer months, this process is reversed to provide cooling. This system is the most efficient type of heat pump—supplying 100% of your heating, cooling, and hot water needs.

These heat pumps are a great option for properties with sufficient lawn space to accommodate the system.

Air-to-Water Heat Pumps

Air-to-water heat pumps use the same concept as an air source heat pump for drawing out heat from outdoor air. The difference is that it delivers the heat via water piped through your home or business (rather than hot air). These highly efficient heat pumps provide a total solution for heating, cooling, and hot water supply.

These heat pumps are a great option for homes or businesses with radiant heating.


  • Cost: Compared to heating and cooling with oil, propane, or electric resistance, heat pumps allow you to save money on energy bills.

  • Flexibility: Heat pumps can be installed with or without ductwork and can heat and cool either an individual room or your whole home or business.

  • Comfort & Convenience: Heat pumps provide all-in-one comfort: Heating, cooling, and dehumidification are all in one system.

  • Greenhouse Gas Emissions: Heat pumps emit less greenhouse gasses, which is better for the environment.
