Absolutely! Heats pumps systems are much more efficient than they used to be and are extremely efficient even in cold weather. You will still need a backup heat source for an air exchange heat pump system but most of the time you won’t need to use it.
A geothermal system harnesses the heat trapped underground to heat your house. By laying a series of pipes several feet below the surface of your yard, we can use the difference between the ground temperature and air temperature to keep your house warm in the winter and cool and you comfortable while saving you money!
