Signs Your Furnace Needs Repair
Call us if you notice any of these:
- No warm air from vents
- Furnace will not turn on at all
- Frequent on-and-off cycling
- Loud banging, rattling, or squealing
- Yellow or flickering burner flame (gas furnace)
- Burning smell that does not go away
- Pilot light will not stay lit
- Higher gas bills with less heat
Gas smell safety note: If you smell gas, leave the house, call your gas utility or 911, and do not switch anything on. After the area is safe, we can inspect the system. If a carbon monoxide detector alerts, leave the home and call 911 first, then call us for system inspection after clearance.
Gas and Electric Furnace Repair
We repair all major furnace brands. Common fixes include ignitors, flame sensors, blower motors, limit switches, thermostats, and control boards. We carry common parts on our trucks to speed up many repairs.
Not sure if you have a furnace or heat pump? Call us. We will identify your system and get heat restored. For broader heating help, see our Heating Repair page. For heat pump issues, see Heat Pump Repair.
What to Do Before the Tech Arrives
Furnace Repair vs Replacement
If your furnace is over 15 years old, needs costly repairs often, or has a cracked heat exchanger, replacement may save money long term. We give honest guidance. We will not push a new unit if a repair is the right call.
