Signs Your Furnace is Experiencing Issues

How do you know if your furnace is doing its job? It can be difficult to tell if your heater is faulty if you believe its performance is the norm. Here are some signs that your furnace may not be working correctly and that you need to schedule furnace repair service in O’Fallon, IL with us. 

  • No Heat in One or More Locations: Finding out that your living room’s nice and heated but your bedroom is freezing cold can be a jolt to the system. Uneven heating is a sign your furnace is in need of repairs, and you should call a professional HVAC company.
  • Detection of a Funny Smell/Gas Odor: Although it’s common to smell the fuel that your furnace uses when turning it on for the first time that season, it generally dissipates when the unit runs for a while. So, if you notice a strange or gas-like smell that persists, give our experts a call so they can diagnose the issue.
  • Blower Fan Continues to Run: Your furnace’s fan should only run when it heats your home. If the fan is set to “AUTO” and constantly runs whether or not your furnace is heating, you may have a possible issue that needs to be addressed.
  • System Runs Constantly: If you notice that your furnace system is constantly running, it may mean you have a clogged furnace blower (or one that needs lubrication). 
  • System Cycles On and Off Rapidly: Another way you can tell that your furnace is abnormal is if the system persistently cycles on and off rapidly. 
  • Hearing Odd Noises (Squealing/Rumbling): It’s true that no heating and cooling system is completely silent. But if you notice your equipment making strange noises like squeaks, pops, and rumbles, it may indicate that something needs to be repaired or replaced.
  • Thermostat Not Working: One of the more obvious signs that your furnace is struggling to function is if you cannot set your thermostat or if it has shut off entirely.
