Furnace Repair in Troy, OH
No heat, cold air from the vents, or a furnace that keeps shutting off.
Common reasons people call us: the furnace will not start, it blows cold air, it starts and then shuts off after a few minutes, it makes a new banging or squealing noise, or the gas bill jumped without the weather getting any colder.
A lot of no-heat calls come down to a dirty flame sensor, a failed igniter, a clogged condensate drain or a blocked vent pipe. Others are a worn blower motor or a failed control. We test until we know which it is, explain what we found, and fix it right the first time.
A furnace that runs is not the same as a furnace that runs safely, so we test for safe operation on every visit. If an older furnace has a problem that makes replacement the better call, such as a cracked heat exchanger, we will tell you, along with an honest answer on what a repair would cost instead.

Frequently asked questions
My furnace is blowing cold air — what's wrong?
It could be a thermostat setting, an ignition or pilot issue, or a clogged filter. It's worth a quick diagnostic — call us and we'll figure it out fast.
My furnace quit — how fast can you come out?
Call us and we'll get to you as quickly as we can, because a furnace failure in an Ohio winter can't wait. We service every make and model across the Miami Valley.
How often should I change my furnace filter?
For most homes, every 1–3 months. A clogged filter is one of the most common causes of furnace problems and higher energy bills.
What if I smell gas?
Leave the house first, call your gas utility from outside, and do not flip any switches on the way out. Once the utility says it is safe, call us.
