Gas Furnace Systems
Gas furnaces are now available in up to 98% with two stage gas valves. There are a vast array of choices for most gas furnaces. Any 80% AFUE units require a flue liner to be installed in all existing flues. 90+ units require two PVC pipes, one for exhaust and one for fresh air. We do a combustion analyzation on gas furnace installations and service to ensure safe and proper operation of your furnace.
