Linthicum Heights HVAC Service | Harwell Mechanical Services

For many local homes, a lack of cooling during our humid summers is often due to two common problems: a refrigerant leak or a frozen evaporator coil, frequently caused by a dirty air filter or low refrigerant. The salty air near the Chesapeake can also accelerate corrosion on your outdoor condenser unit, reducing its efficiency. We recommend scheduling a seasonal tune-up where we can check refrigerant levels, clean the coils, inspect for corrosion, and ensure your system is ready for the season.
