• Sitting in direct South Texas heat
Kool2U diagnoses and repairs AC problems on personal pickups and commercial work trucks with a diagnostic first approach.

Kool2U provides AC diagnostics and repair for many diesel trucks, including trucks equipped with:

​
Truck AC Problems We Diagnose
Kool2U diagnoses truck AC problems including:
• AC blowing warm or hot air
• Weak cooling
• Intermittent cooling
• AC cold while driving but warm at idle
• Refrigerant leaks
• Compressor problems
• Condenser failures
• Evaporator leaks
• Expansion valve problems
• Blower motor failures
• Electrical faults
• Pressure sensor problems
• Wiring and connector damage
• Climate control problems
• Repeated refrigerant loss
• Unusual AC noises
​
Diagnose Before Replacing Parts
A truck that blows warm air does not automatically need a compressor.
A system that repeatedly loses refrigerant should not simply be recharged over and over.
Kool2U uses a diagnostic first approach to determine why the AC is not cooling before recommending repairs.
Testing may include:
• High and low side pressure testing
• Refrigerant leak detection
• Temperature testing
• Compressor operation testing
• Electrical circuit testing
• Blower and airflow testing
• Condenser airflow evaluation
• Control circuit diagnosis
• Visual inspection of hoses and fittings
​
Proprietary Truck AC Leak Detection
Refrigerant leaks are a common cause of poor truck AC performance.
Kool2U uses its proprietary AC diagnostic and leak detection process to help identify leaks before repairs are recommended.
Possible leak sources include:
• AC hoses
• Hose crimps
• O rings and fittings
• Compressors
• Condensers
• Evaporators
• Service ports
• Expansion valves
• Refrigerant connections
Finding the actual source of refrigerant loss helps reduce repeat repairs.
​
Truck AC Recharge & Refrigerant Service
If your truck is low on refrigerant, Kool2U evaluates the system to determine why.
Depending on the truck and system, service may include:
• Refrigerant recovery
• Vacuum testing
• Leak testing
• Refrigerant recharge
• Pressure testing
• Temperature testing
• Verification of AC performance
Kool2U services supported R134a and R1234yf truck AC systems using the proper equipment and procedures.
​
Truck AC Compressor Diagnosis
Truck AC compressors can be expensive.
Before recommending replacement, Kool2U evaluates whether the compressor itself has failed or whether another issue is preventing proper operation.
Possible causes include:
• Refrigerant loss
• Electrical faults
• Compressor clutch problems
• Variable displacement compressor control faults
• Pressure sensor failures
• Restricted refrigerant flow
• Condenser airflow problems
• Internal compressor failure
Accurate diagnosis can prevent unnecessary compressor replacement.
​
Truck AC Electrical Diagnostics
Modern pickup and work truck HVAC systems rely heavily on electronics.
An AC system may have the proper refrigerant charge and still fail because of an electrical or control problem.
Kool2U can diagnose:
• Compressor power and control circuits
• Relays and fuses
• Pressure sensors
• Blower motor circuits
• Wiring damage
• Connector problems
• Ground faults
• Climate control problems
• Intermittent electrical failures

Aaron and his crew have been very helpful, efficient, and accurate with diagnostics and repair to both my fleet of Heavy Equipment as well as our customers machines.
Their versatility and ability to support our unique needs for filed service on Heavy Equipment are unique in the market! Thanks again for all the help!

Thomas A. (Anderson Machinery Company)
Wow, wow, wow!! I don't think words can describe how amazing Aaron and his crew operated. I was stranded and they went out there way to make time for us. To make matters even better, the expertise on our problem was unmatched! They were very detailed and walked us through their service call.
​
As a contractor I have had issues finding a good, trust worthy mechanic. Well I have the best New Braunfels has to offer! Just wish I could package them up and bring back to Dallas. Maybe they will be in Dallas eventually but anyone looking for a honest, hard working, master tech, look no further than Aaron and his crew!!!

So I waited over 12 months to review because I wanted to be 100% sure that the repair was a long-term repair. My ‘08 dodge ram turbo diesel 2500 had no air conditioning and no one that I took it to could fix it and I had literally spent over $1000 by the time I found Aaron and KOOL2U.
​
Not only did Aaron personally find the problem and repair it, but stood behind his employees work & found out that I had additional hidden problems that he resolved as well and was extremely fair on his pricing. Now here I sit in San Antonio with 105° for the last three weeks and I’m loving it with my AC in my truck.
