A Guide to Common Air Conditioning Problems in Dundalk, MD

Understanding the signs of a failing air conditioner can help you know when to call the professionals at ATM HVAC Furnace Repair in Dundalk, MD.

• AC is Not Turning On: This could be a simple tripped circuit breaker or an issue with your thermostat. More serious causes include a faulty transformer or a safety switch that has shut the system down.
• AC is Blowing Warm Air: This is a very common problem. It often points to a dirty air filter restricting airflow, low refrigerant levels due to a leak, or dirty coils that can't properly transfer heat.
• Your Unit is Making Strange Noises: A squealing noise can indicate a belt issue, while a grinding or clanking sound could be a sign of a failing compressor or motor bearings. Any noise outside of the normal hum should be inspected.
• Water is Leaking Around Your Indoor Unit: Your AC system creates condensation, which is drained away. A leak typically means the condensate drain line is clogged or the drain pan is cracked, which can cause significant water damage in your Dundalk, MD home if not addressed.
• The System Runs Constantly but Doesn't Cool: This can be a sign of low refrigerant, a failing compressor, or that your system is improperly sized for your home. It's a major sign of inefficiency that will drive up your Dundalk, MD utility bills.If your air conditioner is showing any of these signs, calling a certified technician from ATM HVAC Furnace Repair is the best way to get a fast, accurate diagnosis and a reliable repair.
