Powered by electricity, Carrier heat pumps can handle both heating and cooling. During the 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.

If you’re interested in installing a heat pump, give us a call and we’ll schedule a free on-site estimate to walk you through your options.
