A leaking AC line is one of the most common reasons a truck loses its cooling. Vibration, heat, and rubbing wear down hoses, fittings, and seals over time. We locate leaks and repair or replace damaged AC lines, hoses, and fittings on heavy-duty trucks and equipment. Once the repair is done, we evacuate and recharge the system so it cools the way it should. Many line repairs can be done on-site with our mobile mechanic service, and larger jobs are handled in our shop.
