Common Questions

How often should an HVAC system be replaced?

Most systems get replaced every 15 to 20 years. AC units and heat pumps usually wear out before gas furnaces do.

Can I replace only the AC and keep my furnace?

Yes, as long as the indoor coil and blower work with the new AC. A mismatched system loses efficiency and can void the warranty.
