HVAC System Repair & Service

Air Conditioning (A/C) Service & Repair

Repairing the HVAC air conditioning system on a semi or heavy-duty truck can be a complicated and involved process. 

The A/C system is made up of several components, including the: 

  • Compressor
  • Condenser
  • Evaporator
  • Control unit
  • Various hoses and belts

If any of these parts fail, the system will not work properly and can cause significant problems for the driver. 

In addition, the system requires specific refrigerants and oils that must be properly maintained and replaced as needed. 

If the system is not repaired correctly, it can lead to poor airflow or complete failure. 

It is important to have the experienced technicians at Wayne Truck & Trailer handle any repairs to ensure that the HVAC system functions as it should.

What Our Customers Are Saying About Us

I had a roadside breakdown on I-70 due to a coolant fitting failure. They were easy to work with and the tech had made this same repair previously on other trucks. The fitting is one that connects the engine head to heater core. They had to stop by a Paccar dealership (in Dayton?) to get the part and then make the roadside repair. They gave me a price estimate before heading my way and the final bill was somewhat less since I didn’t need as much coolant as estimated. Easy to work with, I would recommend them and use them again myself – if needed. My only complaint was that they didn’t open until 8a. I would’ve given 5 stars if they could have rolled at 6a. The parts dept at Paccar opened at 7a so it wasn’t a huge impact on the schedule.

I had a bad miss on my Volvo VN with a Volvo D13 engine in it. They had the software to diagnose the problem and were able to replace the bad injector. I was back on the road the same day. Last time I had this problem I took it to a Volvo dealer, and they took a week before e they would even look at it.

Truck Service

My family and I have been traveling for the past 3 weeks in the RV. We have had terrible luck up until this point with our RV. Needless to say, many tows and service repair work. This business has gone above and beyond. They were completely understand, sympathetic, and willing to help until they figured out what the problem was! We had our dogs, kids, cat, and extended family there with us all day. There were no problems with that. We felt comfortable and at ease here! I would highly recommend this shop to anyone. The quality, communication, and price was just what we needed! Thank you to all who helped!

Wayne Truck & Trailer came to my rescue when it came to an unusual situation with a tire on my Truck. After sitting at a Loves in Dayton for 4 hours waiting for my turn to have this tire fixed, only to find out they didn’t have the size I needed. After looking around, Wayne Truck & Trailer came through!! Cody really took care of our situation, and the company was well pleased.

Thank You, Cody and Wayne Truck & Trailer, for everything. Please keep up the great work.

Our motorhome broke down in Greenville, OH and their techs spent a few hours fixing it. They were pleasant to deal with and got us back on the road as quickly as they could.

“My company travels all over the US with trucks and enclosed trailers. We had two equalizer straps tear off of the bolt/leaf spring on one side. Google suggested Wayne Track and Trailer nearby. Great choice! Norm was excellent at the front desk and the guys in the shop were very helpful and knowledgeable. They were able to get us repaired and back on the road in a just a couple of hours. Highly recommended!”
