Waking up to a cold house in January is miserable. With older furnaces it can also be unsafe. Our techs diagnose fast, carry the common failure parts on the truck, and run a carbon monoxide safety check on every single visit, free.
Most furnace failures come down to a short list: ignitors, flame sensors, blower motors, and control boards. We stock all of them for the major brands. That is why most of our heating calls end with heat restored the same day.
Every visit ends the same way: we test full heating cycles, show you the readings, and put the warranty in writing.

Recent furnace repair reviews
“Furnace died in a January cold snap out in Summerset. Summit had heat back the same afternoon, ran a carbon monoxide safety check before leaving, and walked me through what actually failed. Fair price, no upsell, and they called ahead when the tech was thirty minutes out.”Furnace Repair · Verified customer
“Furnace quit on a cold morning in Rossmoor. They had heat back the same day and ran a carbon monoxide check without me asking. Took one star off because the tech ran 20 minutes into the window, but they called ahead.”Furnace Repair · Verified customer
“No heat at 6am in January and a real person answered the phone. The tech had the part on the truck and ran a CO safety check before he left. We use Summit for everything now.”Furnace Repair · Verified customer

Questions homeowners actually ask
How much does furnace repair cost?
Most repairs run $159 to $780 depending on the part. The $89 diagnostic is applied to the repair, and you approve the price before work starts.
Is my furnace dangerous?
Usually not. But cracked heat exchangers and venting problems are serious. That is why every visit includes a free carbon monoxide check, and we show you the readings.
Repair or replace my furnace?
If the furnace is over 15 years old and the repair tops a third of replacement cost, we show you both numbers. The decision is yours. Our techs do not earn commission.
Do you service all brands?
Yes. Carrier, Trane, Lennox, Rheem, Goodman, Bryant, American Standard, and more.
Do you check for carbon monoxide?
On every visit, free. We test, show you the numbers, and explain what they mean before we leave.
Why does my furnace short cycle?
Usually a dirty filter, a failing flame sensor, or an oversized unit. The first two are cheap fixes. We diagnose before we guess, and you approve the price before we repair.
Should I get a tune-up before winter?
Yes. A fall tune-up catches cracked ignitors and weak sensors before the first cold snap, when the repair calendar fills up fast. Summit Club members get it included.
