What Is Going Wrong?
Not every no-heat call is a furnace fault. A thermostat with dead batteries, loose wiring, a bad location, or a failed heat relay can stop the furnace, make it run constantly, or make it short-cycle. We check the thermostat, its wiring, and the furnace's response to a call for heat before replacing furnace parts.
Common Causes
- Dead batteries or a failed thermostat display
- Loose, corroded, or miswired thermostat connections
- A thermostat in a draft, in direct sun, or above a heat source
- A heat anticipator or relay setting that short-cycles the furnace
Signs You Need This Service
- The thermostat says one temperature, the room feels another
- The furnace never starts, even with a new battery and a high setpoint
- The furnace runs, but never shuts off
- The furnace starts and stops every few minutes
What We Check, In Order
- Thermostat output at the furnace control board
- Wiring continuity and connections at both ends
- Thermostat location and temperature sensing
- Furnace response to a direct call for heat, bypassing the thermostat safely
Why Choose Us for This Furnace Job
- We diagnose in order, so the real fault gets fixed, not just the obvious part.
- You get an upfront price before work starts, and you decide with no pressure.
- After the repair we test ignition, airflow, and safety switches, and we clean up before we leave.
Repair or Replace?
| Situation | Honest next step |
|---|---|
| One failed part, furnace under 12 years old | Repair is usually the right call |
| Repeated failures, or a cracked heat exchanger | Price replacement, and do not run an unsafe furnace |
| Repair near half the cost of a new furnace | Get both options in writing before deciding |
Safety note: If you smell gas, leave the home and call from outside. If a carbon monoxide alarm sounds, leave and call emergency services, then call us.
