About Our Heavy-Duty Truck HVAC Services

A properly functioning HVAC system keeps drivers comfortable and helps maintain clear visibility in changing weather conditions. The system relies on components such as the compressor, condenser, evaporator, blower motor, and heater core to provide consistent heating, cooling, and airflow throughout the cab.

Reduced cooling performance, weak airflow, unusual noises, or inconsistent cabin temperatures often indicate developing HVAC problems. For commercial trucks working in and around North Charleston, routine HVAC service helps prevent unexpected failures and keeps drivers comfortable on every trip. 

What Our HVAC Repair Includes

  • HVAC System Diagnostics: We inspect the air conditioning and heating system to identify electrical faults, airflow restrictions, refrigerant leaks, and failing HVAC components.
  • A/C System Repairs: Our technicians repair compressors, condensers, evaporators, expansion valves, hoses, and related air conditioning components to restore cooling performance.
  • Heating System Repairs: We diagnose and repair heater cores, blend doors, blower motors, thermostats, and other heating system components to restore consistent cabin heat.
  • Refrigerant Service: We recover, recharge, and verify refrigerant levels while checking the system for leaks that can reduce cooling efficiency.
  • Preventive HVAC Inspections: Routine inspections help identify worn components, refrigerant loss, and electrical issues before they lead to complete HVAC system failure.

Symptoms of a Damaged HVAC

HVAC problems can affect driver comfort as well as windshield defrosting and visibility. Weak airflow, inconsistent temperatures, or unusual sounds may come from refrigerant, blower, compressor, or electrical issues. Diagnosing the system early can prevent a smaller HVAC fault from putting additional strain on other components.

  • Noisy Operation: Unusual noises like rattling, banging, or hissing from the HVAC system suggest problems such as loose components, a failing compressor, or a refrigerant leak. These noises are often indicative of a need for immediate repair.
  • Warm A/C: Air conditioning no longer cools properly
  • Electrical Issues: Electrical problems within the HVAC system can manifest as intermittent or non-functioning controls, blown fuses, or failure to start. These issues often stem from wiring problems or faults in the system's electronic components.
  • Weak Heat: Heater output becomes noticeably lower.
  • Refrigerant Leak: Refrigerant leaks are a serious concern and can be identified by a hissing sound, ice formation on components, or a noticeable decrease in cooling efficiency. Prompt repair is necessary to prevent damage to the environment and the HVAC system.

"I HIGHLY RECOMMEND THIS SHOP TO ANYONE IN THE AREA, NEEDING ANY REPAIRS DONE!!!!Every one of them were very polite, transparent, courteous, and respectful. My truck needed 2 new injectors, they ordered them IMMEDIATELY. Since the truck wasn’t going to be done that day, the one owner gave me a ride to the hotel, avoiding me from getting an uber. The next morning the other owner, out of his own pocket, got me an uber back to their shop. These guys are very knowledgeable in what they do!!"

"My experience at General Diesel has been absolutely wonderful. The workers there show great customer service and the service on my vehicle was terrific. I recently brought my vehicle into the shop last Friday and ask for it back by Wednesday. I really wasn’t expecting for the vehicle to be serviced and complete, but General Diesel had the issue with the vehicle complete by Tuesday evening. Thank you General Diesel. I will definitely be coming back soon!"

Harris Borden

"I had a complex electrical fault in my Kenworth T680 truck. They did everything they could and finally detected the fault and repaired it.

If you have a Kenworth truck, you should definitely go to GENERAL DIESEL, not a Kenworth dealer."
