Air Conditioning Service

No one wants to sit in a hot, stuffy truck cab. If your air conditioning unit is not running as it should, one of our trained air conditioning specialists will inspect your fleet vehicle’s air conditioner, all lines, the evaporator, and the compressor for leaks and wear.

The air conditioning unit in your vehicle operates similarly to a refrigerator. Your vehicle’s air conditioning unit is designed to move heat from the inside of your truck to the outside of it.

Your vehicle’s air conditioning unit has six major components:

  • The refrigerant carries heat.
  • The compressor circulates and compresses refrigerant within the vehicle’s cooling system.
  • Your vehicle’s condenser changes the refrigerant from gas to liquid and expels heat from the cab.
  • The expansion valve (sometimes called the orifice tube) is a nozzle that simultaneously drops the pressure of the refrigerant liquid, meter its flow, and atomize it.
  • Your vehicle’s evaporator transfers heat to the refrigerant from the air blown across it, cooling your truck.
  • The receiver or dryer filters your vehicle’s refrigerant and oil, removing moisture and other contaminants from them.

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 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 auto or fleet truck to Santin Auto and Truck Repair. 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.

Heating

In the winter months, waiting for your fleet truck to heat up can sometimes feel like an eternity. If your truck’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 Santin Auto and Truck Repair if its heating unit is not working as it should.

Esteban provided hands down the best customer service. My uhaul vehicle broke down and he was unable to fix it, it needed a tow. Esteban ensured I was safe and in a good place with uhaul sending a tow before he left. He even went out of his way to get me water and snacks since I have been on the side of the road for 3 + hours. There are good people in this world and Esteban is one of them. Amazing service and an even better human being.
