Furnace Repair
Furnace not heating, short-cycling, or making noise? Red Seal certified furnace repair, diagnosed on site and quoted flat-rate.
A furnace that's struggling mid-winter isn't something to wait out. We diagnose gas furnaces on site — ignition issues, blower problems, uneven heat — and give you one flat-rate price before any repair begins.
Signs you need furnace repair.
- The furnace is blowing cold or lukewarm air
- It's short-cycling — turning on and off repeatedly
- Banging, rattling, or squealing sounds from the unit
- The pilot light or ignitor won't stay lit
- Rising energy bills without a change in usage
Common causes.
A failing ignitor or pilot
Electronic ignitors and pilot assemblies wear out over time and are one of the most common reasons a furnace won't start.
A dirty or clogged filter
A blocked air filter restricts airflow, forcing the furnace to work harder, and can trigger safety shutoffs.
Thermostat or control board issues
A miscalibrated thermostat or a faulty control board can cause a furnace to short-cycle or ignore calls for heat.
A worn blower motor or belt
A blower motor nearing the end of its life often announces itself with noise before it fails outright.
Repair vs. replace.
We diagnose first and recommend the option that actually fits — not the more expensive one.
Repair usually makes sense when:
- — The heat exchanger is intact and the issue is a component like an ignitor, blower, or control board
- — The furnace is within its typical efficient service life
- — Repairs have been infrequent
Replacement usually makes sense when:
- — The heat exchanger is cracked or corroded
- — The furnace is old and repairs are becoming frequent
- — Efficiency has clearly dropped despite maintenance
Our approach: We diagnose before recommending anything — most furnace calls are a single component repair, and we'll tell you plainly if the unit is nearing the point where replacement makes more sense.
