One of the worst things that can happen to a truck or bus driver is for their air conditioning to give out during the dog days of summer. This is especially true in New Jersey, where we see our fair share of blistering summer days and prolonged heat waves every year.

Why Isn’t My Truck A/C Working?

If your A/C doesn’t seem to be working – particularly if it’s the first time you’re using it after winter – the issue could be:

• There is a refrigerant leak and the unit does not have enough refrigerant to work properly.
• Dirt and road debris in condenser cooling fins blocking air flow thru condenser.
• There is an electrical problem, such as a blown fuse or loose connection.
• The compressor belt is broken.
• The clutch is sticky from being in disuse.
• The cab air filter is restricted causing poor air flow thru vents, and you simply didn’t realize it as much with heating as you now do with cooling.

The Importance of Preventative Maintenance

Some newer models of trucks have more sophisticated climate controls which are electronically controlled by a separate module and a some even have a “check A/C” light. Even if your fleet is equipped with this feature and it is not lit up, you should still seek an A/C checkup each spring. A little bit of preventative maintenance in April or May can go a long way toward avoiding a meltdown (not to mention the longer repair times) in June or July when everyone is in a rush to repair their A/C due to the extreme temperatures.
