A Guide to Common Furnace Problems in Dundalk, MD


Understanding the signs of a failing furnace can help you know when to call the professionals at Zoop HVAC in Dundalk, MD.

  • Furnace is Not Turning On:Possible Causes: This could be a simple tripped circuit breaker or an issue with your thermostat. More serious causes include a faulty transformer or control board.
  • Furnace is Blowing Cold Air:Possible Causes: This common problem often points to a dirty flame sensor, an issue with the pilot light or electronic ignition system, or an overheating issue that is shutting off the burners.

  • The System is Short-Cycling (Turning On and Off Frequently):Possible Causes: This is often caused by a dirty, clogged air filter restricting airflow and causing the system to overheat. It can also be a sign of an incorrectly sized furnace or a faulty thermostat.
  • Your Carbon Monoxide Detector Goes Off:This is a serious emergency. If your CO detector sounds, evacuate your home immediately and call 911 or your gas company. This can be caused by a cracked heat exchanger in your furnace, which is a life-threatening issue.If your furnace is showing any of these signs, calling a certified technician from Zoop HVAC is the best way to get a fast, accurate diagnosis and a reliable repair.
