Ductless Mini-Split Repair in Bucks & Montgomery County, PA

Conducted a heating system diagnostic, after the customer reported a recurring PC03 error and the heat triggered a fire alarm in the living room of a rental home. After checking system operation, we found the refrigerant may be slightly low, though the issue can also be caused by factors such as a dirty filter or the system reaching operating limits during very cold temperatures below 32°F, which can lead to a temporary lockout. At this time, the system is operating, and we advise monitoring performance, with a plan to review repair or replacement options if the issue becomes more frequent.

Wrapped up a diagnostic visit at a homeowner’s property to address ongoing issues with a Mitsubishi Electric indoor unit and a Carrier central air system. The Mitsubishi mini-split was found low on refrigerant, with quick-connect fittings using pipe sealant instead of proper field flaring, and the high-voltage wire run without conduit or proper support, contributing to operational issues. The Carrier heat pump’s compressor had failed and was tripping the breaker, preventing heating. Both systems are under warranty, and the homeowner was advised on repair options to restore safe and reliable heating and cooling throughout the home.
