When you start your vehicle’s air conditioning system, the compressor works by putting the refrigerant under pressure, sending it to the condensing coils, which are generally in front of your vehicle’s radiator. The condenser expels hot air to outside the cab, cooling the air within the vehicle. When this happens, the refrigerant is cooled, and it changes from a gas to a liquid, which then passes through the expansion valve and to the evaporator.
Once the evaporator receives the liquid-state refrigerant, it loses pressure and cools the remaining liquid. The vehicle’s blower moves air across the evaporator and into the vehicle’s interior. If you keep your air conditioning unit turned on, the refrigerant goes through this cycle continuously.
If any of these components is damaged, it can turn your cool truck into a furnace during the summer months. Your vehicle’s air conditioning issue could be as simple as topping off refrigerant to replacing a valve. When your air conditioning unit is not working as it should, bring your vehicle to Little's Diesel Service. One of our trained air conditioning specialists will inspect your truck’s air conditioner, all lines, the evaporator and the compressor for leaks and wear.
In the winter months, waiting for your vehicle to heat up can sometimes feel like an eternity. If your vehicle’s cab stays frigid in the winter, it can be exhausting to your driver and even detrimental to their health. Make sure your vehicle’s cab is always comfortable and bring your vehicle to Little's Diesel Service if its heating unit is not working as it should.
