There’s heating bills! How big they grow may depend on the type of furnace you own. Let’s compare:
How much it costs
Need to know
The average lifespan (in years) of a modern gas furnace is: 15 to 20 years.
People assume furnaces will last 25 years or more but that’s no longer the case, says registered home inspector Rob Parker. “Older furnaces are less complicated and could last up to 30 years, but can cost twice as much to heat your home,” says Parker.
Overall Efficiency
The AFUE measure
The Annual Fuel UtilizationEfficiency rating tells you how much heat a furnace produces compared to the energy it uses to produce it.If an older furnace operates at 50% AFUE, 50 cents of every dollar spent is, well, going up in smoke.
