Signs your furnace needs repair
Cold snaps in the Delaware Valley are hard on aging equipment. Get in touch if you notice:
- No heat, or the furnace starts then shuts off before the house warms up.
- Rooms far from the unit stay cold while others overheat.
- A burning, dusty, or sulfur-like smell when the system kicks on (leave immediately if you smell gas).
- Banging, squealing, or rattling from the closet or basement unit.
- The pilot or igniter fails repeatedly, or the flame looks yellow and lazy instead of steady and blue (on a gas furnace).
- The blower runs constantly, or cycling is much more frequent than last winter.
- Your energy bill is up sharply with the same thermostat settings.
What to check before you call
These checks are safe for most homeowners and often explain a “no heat” call:
- Thermostat. Set to Heat, with the temperature above the current room reading. If it uses batteries, replace them.
- Furnace switch and breaker. Many furnaces have a wall switch nearby that gets turned off by accident. Confirm the breaker hasn't tripped.
- Filter. A packed filter can cause overheating and a safety shutoff. Replace it if you can't see light through it.
- Vents and returns. Make sure rugs and furniture aren't blocking supply vents or a return grille. Closed vents in unused rooms can also throw the system off.
- Outdoor unit (heat pumps). In winter, a heat pump may frost over and defrost on its own. A unit buried in snow or ice needs clearance around it. Don't chip ice off the coil with a tool.
If you smell gas or a carbon monoxide alarm is sounding, don't keep troubleshooting. Leave the building and call 911 or your gas utility.
How a heating repair visit usually goes
We'll call you within 1 hour during business hours to confirm what's going on and schedule. Our techs check ignition, safety switches, airflow, the heat exchanger (visually, and with additional testing if something looks off), and the blower. For heat pumps, we also look at defrost and the outdoor unit. You'll get a price before we do the work. If the better path is a replacement, we'll say so and walk through that estimate too.
Typical furnace repair prices
$150–$800
A diagnostic visit plus a typical repair — igniters, flame sensors, capacitors, inducer motors, and similar parts — often lands here. Heat exchangers and major assemblies cost more. Estimates only, based on typical mid-Atlantic ranges. We'll price your job before work starts.
Furnace and heating questions
The furnace blower runs but there's no heat. What should I do?
Check the thermostat (Heat, and a set-point above room temperature), the furnace switch (it looks like a light switch), and the breaker. Look at the filter — a clogged one can cause the unit to shut down on a safety. If the igniter clicks and nothing happens, or you smell gas, leave and call your gas utility. Otherwise, book a callback and we'll go through it with you.
How much does furnace repair cost around Philadelphia?
A diagnostic visit plus a typical repair often falls in the $150–$800 range. Heat exchangers and other major parts are higher. These are estimates based on typical mid-Atlantic work, not a formal quote. You'll know the price before work starts.
Is it safe to keep running a furnace that makes a banging sound?
Turn it off and call us. Delayed ignition (gas that builds up and then lights) can cause a bang, and a cracked heat exchanger is a more serious safety issue. Don't keep resetting a furnace that shuts down on a fault.
Do you work on heat pumps and boilers too?
We repair furnaces and heat pumps used for heating. If you have a boiler or radiant system, tell us when we call — we may or may not be the right fit, and we'd rather say so up front.
It's after 8pm and we have no heat. What now?
Call or submit a request. After hours and on Sunday, we'll call you first thing at 8am the next business day. If you smell gas or a carbon monoxide alarm is sounding, leave and call 911 or your utility immediately.
