FAQ's

Why is my semi-truck AC blowing warm air?

The most common causes for a truck AC blowing warm air are low refrigerant levels due to a leak, a clogged cabin air filter restricting airflow, or a failing AC compressor. In heavy-duty trucks, a malfunctioning blend door actuator or dirty condenser coils can also prevent the system from cooling properly.

Can a mobile mechanic fix or recharge my truck's AC?

Yes. Our mobile mechanics are equipped with specialized heavy-duty diagnostic tools, vacuum pumps, and refrigerant to evacuate, leak-test, and recharge your system right on the side of the road or at the weigh station. We also replace major components like compressors and blower motors on-site.

What are the signs my heavy-duty AC compressor is failing?

Warning signs of a failing AC compressor include a squealing or grinding noise when the AC is turned on, inconsistent cooling, or the AC clutch failing to engage. If you notice these symptoms, it is critical to have the system inspected before the compressor seizes and contaminates the entire HVAC system.

How much does commercial truck AC repair cost?

The cost of truck AC repair depends on the exact issue. Minor services like a diagnostic check and standard system recharge are on the lower end, while major repairs requiring a full system flush and compressor replacement represent a larger investment. We provide transparent, upfront estimates before any work begins.

Do you repair APUs (Auxiliary Power Units) as well as cab ACs?

Yes. We service and repair major APU brands, including Thermo King and Carrier. Whether your APU has a cooling fault, electrical issue, or needs routine maintenance, our mobile technicians can get it running so you don't have to idle your main engine during rest periods.
