Air Conditioning Repair in Sacramento, CA

ProTech Service provides professional air conditioning repair in Sacramento, California, and throughout the surrounding Sacramento region. We specialize in troubleshooting, servicing, and repairing residential, commercial, and industrial air conditioning systems, from traditional central AC systems to large commercial rooftop equipment.

Whether your air conditioner is blowing warm air, struggling to maintain temperature, experiencing poor airflow, making unusual noises, or has stopped operating completely, ProTech Service can diagnose the problem and provide a dependable repair solution.

Residential & Commercial Air Conditioning Repair

Sacramento's hot summer weather puts heavy demand on air conditioning equipment. ProTech Service services central air conditioners, split systems, heat pumps, ductless mini-splits, air handlers, condensing units, evaporator coils, thermostats, zoning controls, and other cooling equipment.

We diagnose common AC problems including refrigerant-related issues, frozen evaporator coils, clogged condensate drains, compressor problems, condenser and evaporator fan failures, electrical faults, thermostat problems, weak airflow, and systems that continuously run without properly cooling the building.

Rooftop Units, RTUs & Package Unit Repair

ProTech Service also specializes in commercial rooftop air conditioning unit repair, RTU repair, and packaged HVAC unit service throughout Sacramento and surrounding areas.

Rooftop units and package units are commonly used for restaurants, retail stores, offices, commercial buildings, warehouses, industrial facilities, schools, commercial kitchens, and other businesses. These systems combine major heating and cooling components into a single packaged unit, making proper diagnosis and maintenance essential for reliable operation.

We troubleshoot RTUs and rooftop package units with problems such as insufficient cooling, compressor failures, refrigerant issues, condenser fan problems, blower motor failures, electrical and control faults, thermostat problems, damaged contactors and capacitors, clogged coils, poor airflow, and units that will not start or maintain the desired temperature.
