When your ductless system struggles, SumZero Energy Systems delivers Mini Split Repair that diagnoses the issue quickly and fixes it right the first time.

Typical problems we solve include poor heating or cooling, short cycling, frozen coils, water leaks, clogged filters, unusual noises, unpleasant odors, thermostat or remote failures, and refrigerant leaks. Repairs may involve sealing and recharging refrigerant, cleaning and sanitizing coils and drains, replacing capacitors, control boards, or fan motors, recalibrating sensors, and optimizing system settings for peak efficiency.
