Signs You Need Furnace Repair

If your furnace won’t cycle on when it should, or if lowering the thermostat three degrees doesn’t trigger your furnace to start, you need furnace repair. Although this seems like the most obvious sign your furnace is in distress, there are others to look out for. If you notice any of the following signs, be sure to give us a call and schedule your furnace repair in Deerfield:

  • Your furnace won’t turn on – If your furnace doesn’t turn on at all, you need furnace repair to fix the problem.
  • Your furnace turns on, but won’t heat your home – If cool air is coming from your vents, or your furnace runs but your home is still cold, call a local heating specialist to diagnose the issue.
  • Your furnace makes loud banging or clanking noises – Your furnace naturally makes noises when it heats your home, but any loud banging, clanking, or unnatural sounds are a warning sign it’s about to breakdown. You may have a broken fan blade or a variety of other issues.
  • Your furnace’s pilot light is out – If you have a gas furnace and your furnace won’t turn on, your pilot light may need to be relit. This is a dangerous task and should only be done by a certified HVAC professional.
  • Your furnace unevenly heats your home – If you notice certain areas of your home are colder than others, you may have dirty or clogged air ducts, a faulty pilot light, or a broken thermostat.
  • Your furnace/home smells like natural gas – If you smell natural gas coming from your vents, turn off your furnace, leave your home, and call the local authorities immediately. A gas leak is very dangerous and potentially fatal, so it’s important to take precautionary steps to find and fix the leak immediately. Once the leak is fixed, schedule furnace repair in Deerfield.
  • Your energy bills have risen unexpectedly – You might not notice your furnace needs repairs, that is, until you receive your utility bill and it’s 50 percent higher than last month! If your energy bills have risen.

We repair all furnace makes and models, including gas and electric furnaces from popular brands such as American Standard, Bryant, Carrier, Goodman, Lennox, York, and more!
