Warning Signs of HVAC Trouble in Catonsville, MD

A chemical smell can signal a refrigerant leak, which should only be handled by a licensed technician. Property owners in Catonsville, MD who do not ignore these symptoms often avoid a much larger repair bill.

Repeated repairs on an older system are another clue. As a general guideline, a system past 12 to 15 years old that needs a costly repair is often better replaced than patched. You will get an honest comparison so the decision stays in your hands, and payment options may be available.
