When Your Mini Split Stops Working, We’re On It

A mini split that’s blowing warm air in July or icing over in January is more than an inconvenience — it’s a system warning. Most mini split problems stem from refrigerant pressure issues, sensor failure, drainage blockage, or electrical faults. Each requires a different diagnostic approach, and each gets worse the longer it’s ignored.

Our HVAC techs carry refrigerant gauges, manometers, multimeters, and OEM-spec parts for all major mini split brands. Most repairs are completed in a single visit. We provide a written diagnostic and a flat-rate repair quote before we touch a single component.
