Air Source Heat Pumps Basics

Why should I consider an air source heat pump?

Air source heat pumps provide many advantages over traditional fossil-fuel or electric resistance systems including:

Energy bill savings. If you heat with propane, oil, or electric resistance heating, you could save hundreds of dollars a year on your heating bill by installing a heat pump.

Efficient all-in-one heating and cooling. Heat pumps provide heating, cooling, and dehumidification in the same system. Improve the comfort of your home year-round!

Flexibility. Heat pumps come in ductless and ducted varieties and can be installed to address different needs—whether you want to replace your existing system or just want to add heating or cooling to one or a few rooms.

Lower your carbon footprint. Recognized by the State as a clean heating and cooling technology, heat pumps will help you reduce your greenhouse gas emissions.

Consider cold climate air source heat pumps to be the cleaner, greener alternative to fossil fuels—an alternative that also provides high-efficiency air conditioning at the same time!

How do air source heat pumps work?

Rather than generating heat, a heat pump transfers it in and out of a building. Heat pumps use the same process that makes a refrigerator or air conditioner work: think about it as an air conditioner that can also run in reverse!

Heat pumps can be ductless, providing heating and cooling to individual rooms of your home, or ducted, using your existing or new ductwork to serve as a central heating and cooling system.

Is a heat pump right for me?

Do you heat with oil, propane, or electric resistance and want to save on your energy bill?

Switching to a heat pump system could save you hundreds of dollars a year on your home heating bill even if you’re not ready to replace your whole system yet.

Do you want to add air conditioning but don’t have the ductwork for a central system (or just want to ditch the window units)?

Ductless air source heat pumps can help you reclaim your windows from noisy window AC units and provide you with all of the benefits of a quiet, central air conditioning system without needing to spend thousands just to put in the ductwork!

Does your home have hot and/or cold spots?

No need to replace your whole system: a ductless heat pump can be installed in the zone of the hot or cold spot to provide extra heating or cooling.

Do you want to convert your home to gas but don’t have access in your neighborhood?

Consider a heat pump system to be a cleaner, greener alternative! Heat pumps can provide heat at comparable prices to gas with lower emissions—and you get high-efficiency air conditioning at the same time!

Do you want to have more control over the temperature in individual rooms?

Ductless heat pumps are often referred to as “zoned home comfort solutions.” With ductless heat pumps, you can place indoor units in different zones of your home so that you only need to heat or cool the room that you’re in.

Is your furnace or central AC system over 12 years old? 

If so, your system may be approaching the end of its expected lifetime. Consider early retirement: replace your system proactively with a more efficient ducted or ductless air source heat pump.
