Repair or Replace Your Furnace? Start With the 50% Rule

DOE Furnace Rule: Why the Venting Drives Your Quote
Condensing furnaces vent through plastic pipe out a sidewall. In a hallway closet, that route plus somewhere for the condensate to drain is the real cost.

New Furnace Efficiency: What 56% to 98.5% AFUE Means
An old natural-draft furnace with a standing pilot runs 56 to 70% AFUE. What the second heat exchanger, sealed combustion and a modulating burner do.

Gas Furnace Installation: The Seven Steps, In Order
Sizing from the house, a low-NOx model the South Coast AQMD allows, the permit and duct test, then startup. Where homeowners get short-changed.
