Preventative maintenance is the key to protecting your investment.

Absolutely. Modern cold-climate air-source heat pumps are designed to operate efficiently in temperatures well below freezing. For the absolute coldest days of the year, they can be paired with a supplemental heat source (like electric resistance strips or a dual-fuel setup with a furnace) to ensure your home is always warm and comfortable.
Savings vary based on your current heating fuel, your home's insulation, and the efficiency of the new unit. However, many homeowners who switch from oil, propane, or electric resistance heating to a high-efficiency heat pump see their annual energy costs reduced by 30-60% or more.
With regular professional maintenance, an air-source heat pump typically lasts 15 to 20 years. Geothermal systems are even more durable, with the indoor components lasting over 20 years and the underground loop system lasting 50 years or more.
