Heating and furnace repair, diagnosed with real measurements.
When your heat goes out, you need the cause found, not guessed. We test ignition, safety controls, electrical parts and airflow, then explain your options before any work starts.
Common heating problems we repair
Most no-heat calls trace back to a handful of parts. We find which one, and why it failed.
Symptoms we diagnose
- Furnace won't start or blows cold air
- Ignition problems: ignitor glows but no flame, or no glow at all
- Short cycling: turns on and off every few minutes
- Pressure switch, limit switch or flame sensor faults
- Blower runs nonstop or not at all
- Thermostat not calling for heat
- Strange noises, smells or a burner that won't stay lit
No heat right now?
Check that the thermostat is set to Heat with fresh batteries, the furnace switch is on and the filter isn't clogged. If you smell gas or a CO alarm sounds, leave the home and call your gas utility or 911 first.
Still no heat? We answer emergency calls 24/7.
How we diagnose a heating problem
Safety first
Check for gas odor, flue condition and venting before running the furnace.
Electrical measurements
Voltage, amperage, capacitors, ignitor resistance and control board signals.
Combustion & airflow
Flame signal, temperature rise and, where applicable, combustion testing.
Findings & options
Photo report with the cause, the repair and anything that can wait.
