What furnace repair involves
A furnace repair visit is a diagnostic first. We read the control board, check gas pressure and temperature rise, and verify the safeties are doing their job instead of being bypassed by a previous repair.
Diagnosis and repair of gas, propane and oil furnaces — ignition, flame sensors, blowers, boards and heat exchangers.
Common problems and warning signs
- Short cycling — on and off every few minutes
- Loud bang or rumble at start-up
- Rooms furthest from the furnace never warm up
- Grinding or squealing from the blower compartment
- Furnace runs constantly but never reaches the set temperature
What the repair involves
After the repair we run the furnace through a full cycle and check temperature rise, static pressure and draft. A furnace that starts is not the same as a furnace that's right.
When replacement makes sense
We don't condemn furnaces to sell equipment. When a replacement is genuinely the right call, you'll get the reason, the options, and a price — with no pressure to decide on the spot.
Questions from Green Township homeowners
- Can you come out the same day?
- For a no-heat call we try to, and voicemail gets a same-day callback. Leave your name, address and what the system is doing.
- Do you work on oil furnaces?
- Yes — gas, propane and oil. Say which one you have when you call so the right parts are on the truck.
