§ 02 Our approach
How we handle a/c & heating
Truck A/C systems take a beating from vibration and road debris. Instead of simply adding refrigerant, we check pressures, find leaks with dye or electronic detection, and inspect the compressor, condenser, dryer and expansion components. A system that is just recharged usually loses that charge again.
On the heating side, we diagnose heater control valves, blend doors, blower motors and resistors, and coolant flow to the heater core. Sleeper HVAC gets checked as well, so drivers rest properly on their off-duty time.

§ 05 FAQ
A/C & Heating questions
Why does my A/C need recharging every summer?
Because there is a leak. Refrigerant doesn’t get used up. We find and repair the leak, then recharge the system.
Can A/C repairs be done on-site?
Many A/C repairs, including leak testing and recharging, can be done at your location.
Do you repair sleeper heaters?
We diagnose and repair sleeper HVAC systems and blower controls. For fuel-fired auxiliary heaters, call to confirm the model.
