Mini-split repair and cleaning
Mini-split problems usually show as a blinking code on the indoor head. Common causes are sensor faults, a clogged drain, low refrigerant from a flare leak, or a dirty blower wheel. Musty smells mean the wheel and coil need a deep cleaning.
- Same-day appointments when available
- Licensed HVAC contractors
- Written price before any repair
Each brand has its own error codes. Note the code and the model number before you call; it shortens the diagnosis.
A deep clean removes the blower wheel or uses a bag-and-rinse kit to wash out mold and dust that the washable filters miss.
