Common Causes We See
Refrigerant Leak
Low refrigerant from a leak is the most common cause of poor AC performance. We locate and repair the leak before recharging.
Failed Compressor
The AC compressor is the heart of the system. A seized or failed compressor results in no cooling at all.
Clogged Condenser
Road debris and bugs can clog the condenser, reducing heat exchange efficiency and cooling performance.
Blower Motor Failure
A failed blower motor means no airflow through the vents, even if the AC system is otherwise functioning.
Electrical Faults
Faulty relays, fuses, or wiring can prevent the AC compressor clutch from engaging.

Frequently Asked Questions
Can you recharge my AC on the side of the road?
Yes. We carry refrigerant and AC service equipment on our mobile service truck. We diagnose the system first to ensure a recharge will hold before performing the service.
My AC blows warm air — what is the most likely cause?
Warm air is most commonly caused by low refrigerant from a leak, a failed compressor, or an electrical fault preventing the compressor from engaging. We will diagnose the exact cause on-site.
Do you work on APU (Auxiliary Power Unit) AC systems?
We focus on the main cab AC system. For APU-specific repairs, we can refer you to a specialist.
