Driving a semi truck without working air conditioning can be tough — especially during hot summer months. If your truck’s A/C is blowing warm air, has a bad smell, or won’t turn on at all, it’s time to get it checked. A faulty A/C system can make long hours on the road exhausting and uncomfortable.
At United Trailer Maintenance, we inspect your entire A/C system — including the compressor, blower motor, refrigerant levels, hoses, and vents. Once we find the problem, we repair or replace the faulty parts to get your system working properly again. We make sure your truck stays cool and comfortable so you can focus on driving, no matter how far you go.
