Furnaces and Air Conditioning

 The Heart of the System

In Northern Michigan, furnaces are the heart of any heating and cooling system. But most people don’t realize that there have been tremendous changes in the efficiency of furnaces and air conditioners today. In fact, most people are unaware that an air conditioner can be used to heat your home. That’s right. An air-source heat pump looks just like an ordinary air conditioner, but in the winter it can heat your home when the outside temperature is above 20 degrees F! Here at Geofurnace, we only sell what we believe is the finest equipment on the market today.



Gas Furnaces

Like heat pumps, furnaces keep your home warm in the winter and serve as an important part of your air conditioning system in the summer. In a furnace, gas or oil is combusted in a burner and then heat produced from that reaction passes through a heat exchanger where it is transferred to the air distribution system. The ductwork throughout a home carries and disperses the conditioned air and the flue or vent pipe releases the byproducts (such as carbon dioxide and water vapor), outside the home. 




Central Air Conditioning

Central air conditioning helps keep your home cool and reduces humidity levels. By transferring heat from air located inside your home to the outside, conditioned and cooled air is left to be re-circulated. Using electricity as its power source, the compressor inside an air conditioning unit pumps coolant, or refrigerant, back and forth to gather heat and moisture from indoors. Warm air from inside is blown over the cooling coil, which is connected to the compressor, and then pumped back into your home.

Air-Source Heat Pumps

Fueled by electricity, heat pumps are used for either the heating or cooling of your home by transferring heat between two reservoirs. In the warmer months the heat pump acts like an air conditioner, moving heat from inside your home to the outside. During winter months, heat from outdoors is transferred to the interior of your home. Even a 20º-Fahrenheit day still produces enough heat to warm a home via a heat pump.
