Signs Your Furnace Needs Repair
Our winters are short, but cold fronts arrive fast. That first chilly morning is usually when a furnace that sat idle all summer shows its first problems.
Call for service if you notice any of these warning signs:
- No heat, or air from the vents that feels lukewarm
- The furnace turns on and off every few minutes (short cycling)
- Banging, squealing, or rattling from the unit or ductwork
- A burning smell that lingers well past the first few minutes of the season
- One or two rooms that never warm up
- Energy bills climbing while your thermostat settings stay the same
Safety first: if you smell gas or your carbon monoxide detector sounds, leave the home and call your gas utility or 911. Once everyone is safe, call us.
Common Furnace Problems We Fix
Most furnace calls trace back to a short list of parts. Our trucks are fully stocked, so we can fix many of these issues on the first visit.
- Ignition and pilot problems: failed igniters, dirty flame sensors, and pilot assemblies that will not stay lit.
- Blower motor and capacitor failures: weak airflow or a blower that will not start at all.
- Thermostat and control board issues: wiring faults, failed relays, or a thermostat that misreads the room.
- Limit switch trips: usually caused by a clogged filter or restricted airflow that makes the furnace overheat and shut down.
- Heat exchanger concerns: cracks that can let combustion gases escape. We check for these during our diagnostic.
- Ductwork and airflow problems: leaks or undersized ducts that make a healthy furnace look broken.
Because we also handle electrical and insulation work, we can tell you when the furnace is fine and the real issue is somewhere else in your home.
Quick Checks Before You Call
A few simple checks can save you a service call. None of them require opening the furnace cabinet:
- Make sure the thermostat is set to Heat and the temperature is set above the current room temperature.
- Replace the batteries in a battery-powered thermostat.
- Check your breaker panel for a tripped furnace breaker.
- Replace a dirty air filter, which can cause overheating and shutdowns.
If the furnace still will not run, leave the internal parts to a professional and give us a call.
