Signs Your Furnace Needs Attention
Most furnace trouble shows up as something you feel or hear before the system quits for good. Call for service if you notice:
- Rooms that never reach the thermostat setting, or air from the vents that feels cool
- A furnace that starts and stops every few minutes, or runs without stopping
- Banging, squealing, grinding, or rattling when the burners or blower come on
- A burning or electrical smell that lasts past the first few days of the season
- Heating bills that climb while your thermostat settings stay the same
If you ever smell gas, leave the house first and call your gas utility from outside.
How We Diagnose and Repair Furnaces
The same symptom can come from very different failures: a dirty flame sensor, a failed igniter, a weak inducer motor, a blocked flue or condensate line, a bad control board, or an airflow problem in the ductwork. Our technicians test the system step by step until they find the actual cause, instead of replacing the part closest to the symptom. You get a plain explanation and the price before any work starts, and the most common parts ride on the truck, so most repairs are finished the same visit.
Repair or Replace Your Furnace?
Most furnaces are worth repairing. When a system is over 15 years old, needs a major part like a heat exchanger, or keeps breaking down, replacement is often the better money. We tell you which way makes sense and why, and our furnace installation team sizes any new system to the home.
Furnace Tune-Ups and Maintenance
A yearly tune-up catches weak igniters, dirty burners, and worn parts before they turn into a no-heat call in January. Book a heater tune-up before the cold weather, or join one of our maintenance plans to stay on schedule every year.
Gas, Oil and Electric Furnaces
We repair every type of furnace on all major brands. Gas furnace repair centers on ignition, burners, venting, and the heat exchanger. Oil furnace repair covers the burner, nozzle, filter, and combustion testing. Electric furnace repair focuses on heating elements, sequencers, and breakers.
Boiler, Radiator and Oil Heat Service
Boiler and Radiator Service
Many older homes heat with a hot water or steam boiler and cast iron radiators instead of a furnace. Our technicians repair and maintain gas and oil boilers, steam systems, circulator pumps, zone valves, and radiator piping, and we bleed and balance systems so every room heats evenly. Learn more about our boiler repair service.
Oil Burner and Oil Boiler Service
Oil heat still warms a lot of homes around Greater Philadelphia, and it needs its own service rhythm. We clean and tune oil burners, replace nozzles and filters, test combustion and draft, and keep oil-fired systems running clean all winter. See our oil boiler services.
Emergency Furnace Repair
When a furnace quits in freezing weather, it stops being an inconvenience fast, especially with young kids, older family members, or pipes at risk. No-heat calls get priority, with same-day service and fast response any time through our emergency HVAC services.
