Why is your car AC blowing hot air? The 5 most common causes, what a fix involves, and why a recharge alone often is not enough.
1. Refrigerant leak
Refrigerant does not get used up. If it is low, there is a leak, often at a hose, O-ring, condenser or evaporator. We use UV dye to find it so the repair lasts.
2. Failed compressor or clutch
The compressor is the heart of the system. If the clutch does not engage or the compressor is worn, the A/C will not cool at all.
3. Blocked or damaged condenser
The condenser sits in front of the radiator and takes a beating from road debris and bugs. Damage or blockage stops it from shedding heat.
4. Cooling fan problems
If the A/C cools on the highway but not in traffic, the electric cooling fan may not be running.
5. Electrical or blend door faults
A bad pressure switch, relay or blend door actuator can keep cold air from reaching you even when the system itself is fine.
