COMMON FURNACE PROBLEMS
Furnace Symptoms & What They Mean
Below are the most common furnace symptoms, what they usually point to, and how we fix them.
No Heat / Furnace Won't Start
Often a failed igniter, tripped safety switch, bad control board, or pressure switch. We test components, fix the root cause, and verify safe operation.
Blowing Cold Air
Can be a failed ignition, dirty flame sensor, or high-limit trips caused by airflow issues. We clean, calibrate, and restore proper heat.
Short Cycling (Starts/Stops Frequently)
Common culprits: clogged filter, overheats from restricted airflow, or faulty thermostat. We correct airflow and safety-limit causes to protect your heat exchanger.
Strange Noises (Boom/Whine/Rattle)
Delayed ignition "booms," blower bearing noise, or loose panels. We address ignition timing, tighten hardware, and replace worn parts.
Burner Won't Ignite / Repeated Lockouts
Dirty flame sensor, weak igniter, or gas valve/control issues. We clean sensors, test the ignition circuit, and repair as needed.
Gas Smell or Soot
Stop and call immediately. This can indicate leaks or improper combustion. We perform gas-tightness checks and combustion analysis to ensure safety.

Likely ignition problems, a dirty flame sensor, or high-limit trips from restricted airflow (often a clogged filter). We'll identify the cause and restore proper heat.
Common causes include dirty filters, restricted vents/returns, overheating, or thermostat/pressure-switch issues. Short cycling can damage components—best to have it checked promptly.
If your furnace is 15+ years old and the repair cost exceeds 25–30% of a new system, replacement is often smarter. We'll walk through costs, expected lifespan, and efficiency gains so you can decide confidently.
