It’s getting older
Many furnaces last 15 to 20 years. Past that, repairs get more frequent and efficiency drops.

Repair or replace?
Signs it may be time
for a new furnace.
A repair is often the right call. These are the signs a new furnace may make more sense. Safety first: if you smell gas (rotten eggs) or your carbon monoxide alarm goes off, leave the house now and call 911 or your gas company from outside.
Repairs keep adding up
If you’re paying for repairs every winter, that money may be better spent on a new furnace.
A cracked heat exchanger
This is a safety problem, not just a repair. It usually means the furnace should be replaced.
Uneven heat
Cold rooms or a furnace that runs and runs can mean it’s worn out or the wrong size.
Gas bills keep climbing
Newer furnaces are much more efficient, so an old one can cost you every month.
Yellow flame or soot
A burner flame that’s yellow instead of blue, or soot around the furnace, needs a technician right away.

Furnace installation FAQ
What size furnace do I need?
It depends on more than square footage. Insulation, windows and ductwork all matter. We size the furnace for your home instead of guessing, because one that’s too big or too small costs more to run and wears out sooner.
Which furnace brands do you install?
We’re an authorized dealer for Trane, American Standard, Carrier, Bryant, Lennox, Goodman, Amana and Daikin, and we’ll help you compare them.
Do you offer financing?

Can you replace the AC at the same time?
Yes. When both are older, replacing the furnace and AC together often makes sense. We can price it both ways so you can choose.
