Why Is My Truck AC Not Cooling Properly?

A common reason is low refrigerant, often due to a leak in the system. Other causes include a failing compressor or a blocked condenser, both of which can prevent cold air from circulating. Having a professional diagnose the issue ensures the root problem is addressed effectively.

How Often Should I Service My Truck’s HVAC System?

It’s best to have your HVAC system checked at least once a year—before the start of summer and again before winter. Regular checks help catch problems early, like refrigerant leaks or worn components. This not only keeps your cabin comfortable but extends the life of the system too.
