In Austin's 105°F summers, a broken A/C is not a comfort issue — it is a health risk. We repair cab air conditioning systems on commercial trucks on-site throughout Austin, Hutto, Georgetown and Central Texas. No shop. No wait. Same-day service.
A/C problems in Texas summer cannot be ignored. Know the warning signs before your system fails completely during a long haul.
Warm or hot air blowing from vents when A/C is switched on
A/C works for 10 minutes then blows warm (refrigerant leak)
Compressor clutch clicking but not engaging
A/C compressor belt squealing or completely broken
Strong musty smell from the air vents
Cab humidity is very high even with A/C running
A/C works fine at highway speed but not at idle
Low refrigerant is the most common cause of warm air from a truck A/C system. We recharge the system with the correct refrigerant (R-134a for most commercial trucks 2000–2023), check for leaks using UV dye or electronic leak detectors, and verify correct operating pressures before leaving your location.
A commercial truck A/C system holds 3.5–5 lbs of refrigerant. We fill to manufacturer specification, not guesswork. If we find a leak, we identify and repair it — otherwise your new refrigerant is gone within days.
Texas Summer Priority: During June–September we prioritize A/C service calls. Heatstroke risk for cab drivers is real. If your A/C failed today, call us immediately rather than waiting.
A clicking compressor that does not engage indicates clutch coil failure. A broken belt stops the compressor entirely. Both are roadside repairs we handle on-site for most major truck brands — Freightliner, Kenworth, Peterbilt, International, Volvo and Mack.
We also check and replace cabin air filters on every A/C call. A blocked cabin filter reduces airflow through the evaporator dramatically — it is a quick, inexpensive fix that dramatically improves cooling performance and is often overlooked.
