Heating & Cooling FAQ

What is the life expectancy of my HVAC system?

Air conditioning units generally last around 15 years or so. If you want your air conditioning unit to live as long as possible, you want to get it maintained once a year. Your heating system should also be maintained once a year.

What brands do you install?

What is a heat pump?

A heat pump is part of a heating and cooling system and is installed outside your home. In cooler months, a heat pump pulls heat from the cold outdoor air and transfers it indoors, and in warmer months, it pulls heat out of indoor air to cool your home. Overall It saves you money on your heating bill.

Do I need HVAC maintenance?

The purpose of regular HVAC maintenance is to keep your system running efficiently for as long as possible. But even if you do a good job maintaining it each component still has a lifecycle.
