Signs You May Need Furnace Repair
If you notice these symptoms, it’s time to schedule a repair:
Furnace Blows Cool Air Instead of Heat
If your vents are pushing out cool or lukewarm air, your system may have a malfunctioning heating element, pilot light, or blower motor issue.
Strange Noises or Odors While Operating
Banging, rattling, or squealing sounds often point to loose components or motor issues, while burning or musty smells could signal electrical problems or dirty filters.
Energy Bills Are Unusually High
A sudden increase in utility costs often means your furnace is working harder than it should.
Furnace Runs Constantly or Cycles On/Off Frequently
Short cycling (turning on and off repeatedly) or running nonstop can be caused by thermostat malfunctions, clogged filters, or overheating.
System Is Over 10–15 Years Old and Showing Wear
Older furnaces naturally lose efficiency and reliability over time.
