An often overlooked, but key component of your heavy duty diesel vehicle is a working Heating and Air Conditioning system. With as much time as a driver will spend in the cab and on the road, a comfortable environment is key to a successful delivery. When crossing the country or sometimes just driving from morning to night, a commercial vehicle can come across a wide variety of weather and temperature conditions. Without a working HVAC system, the only hope for heat relief is an open window and in colder conditions, a closed window can offer only so much warmth. It may seem like a small thing compared to a blown head gasket or a faulty transmission, but a malfunctioning HVAC system can be just as serious. Don’t suffer through the extreme heat and cold, come into United Diesel and let our experts fix that HVAC system today!
