How your car's A/C works
Your A/C compressor pressurizes refrigerant, the condenser releases heat, and the evaporator inside the dash absorbs heat from cabin air. A problem anywhere in the loop means warm air.
Low refrigerant from a leak
A/C systems are sealed, so low refrigerant always means a leak. Common spots are O-rings, the condenser (hit by road debris) and compressor seals.
Recharging without fixing the leak is a short-term fix. We use UV dye to find the leak first.
Compressor or clutch failure
If the compressor clutch isn't engaging, the system can't cool. This can be a failed clutch, a blown fuse, a bad relay or a pressure switch preventing operation.
Weak airflow and blend door issues
If air is cold but weak, a clogged cabin filter or failing blower motor is likely. If one side blows hot and the other cold, a blend door actuator may have failed.
