Professional Auto A/C Repair & Service

When your car's air conditioning stops working—or stops working well—summer driving becomes miserable. At Onsite Automotive Services, we provide comprehensive A/C diagnostics, repair, and service to keep you comfortable year-round.

Our ASE-certified technicians have the equipment and expertise to diagnose A/C problems accurately and make repairs that last. We service all makes and models, from basic systems to the latest climate control technology.

Our A/C Services Include:

A/C System Inspection

We perform a complete inspection of your A/C system, checking refrigerant levels, compressor operation, condenser and evaporator condition, and all related components to identify the source of any problems.

A/C Recharge (Refrigerant Service)

Low refrigerant is the most common cause of weak A/C. We evacuate the old refrigerant, check for leaks, and recharge the system with the correct type and amount of refrigerant for your vehicle.

Leak Detection & Repair

A/C systems are sealed, so low refrigerant usually means a leak. We use electronic leak detectors and UV dye to find leaks, then repair or replace the faulty components.

Compressor Repair & Replacement

The compressor is the heart of your A/C system. When it fails, the system can't cool. We diagnose compressor problems and replace failed units with quality parts.

Condenser & Evaporator Service

Damaged or clogged condensers and evaporators reduce cooling efficiency. We inspect, clean, and replace these components as needed.

Blower Motor & Controls

If air isn't flowing properly, the problem may be the blower motor, resistor, or control module. We diagnose and repair these issues to restore proper airflow.

• Weak or warm airflow from vents
• A/C blows cold intermittently
• Strange noises when A/C is running
• Musty or unpleasant odors from vents
