Split Systems

A split system is a heat pump heating and central air conditioning system that has components in two locations with one part of the system is inside (an evaporator coil attached to a furnace or a fan coil) and the other is outside your home (heat pump or a/c unit / condenser coil).

Gas Furnaces

Gas Furnaces heat air and distribute the heated air through the house using ducts. Bryant Evolution Series gas furnaces provide quiet, smooth, whole-home comfort. You’ll hardly hear them running as you get cozy with up to 98.3 percent AFUE savings.

Heat Pumps

Instead of generating new heat like traditional heating systems, a heat pump works by transferring heat from the air or ground outside into your home. They’re efficient, cost-effective and great for homes with no natural gas service.

GeoThermal Heat Pumps

Geothermal heat pumps (GHPs), sometimes referred to as GeoExchange, earth-coupled, ground-source, or water-source heat pumps use the relatively constant temperature of the earth as the exchange medium instead of the outside air temperature.

Ductless Mini-Splits

No Ductwork in your home? Ductless mini-split systems, are a practical heating and cooling solution for homes lacking ductwork. A ductless heat pump or air conditioner typically consists of two primary components: an indoor unit, typically wall-mounted, and an outdoor compressor unit.

Packaged Systems

Packaged systems combine the evaporator, condenser, compressor, and air handler of a heat pump into one package for homes without room for a traditional split system. They can be placed on your rooftop or in your yard with only ductwork and electrical cables connecting the system to your home.
