Air Isn’t Cold Enough
Weak cooling can have several causes. An A/C system check can help determine whether refrigerant or another issue needs attention.

Keep Your Truck’s A/C Working Properly
A truck air conditioning system relies on the correct refrigerant level, system pressure, and properly functioning components. When the A/C stops cooling as it should, checking the system can help identify the next step.
Possible Refrigerant Leak
Because the A/C system is pressurized, a leak can allow refrigerant to escape and reduce cooling performance. The cause should be checked.
Seasonal Maintenance
A/C and engine coolant concerns are worth addressing as part of regular truck maintenance, especially before demanding weather.
A/C System Service
Checks Before Refrigerant Recharging
A/C systems need to remain properly sealed to operate as intended. Refrigerant loss can reduce cooling, but simply adding refrigerant may not resolve an underlying leak or component problem.
At Lemont Truck Center, Robinair A/C machines are available for A/C service. Our approach starts with checking the system and determining the appropriate service for the problem.
- Check A/C system concerns and cooling performance.
- Assess refrigerant and system pressure as appropriate.
- Address leak-related concerns before or alongside further service.
- Recharge and repressurize the system when appropriate.
Engine Cooling System
Coolant Checks & Rotella Coolant
Coolant leaks and cooling-system problems deserve attention in hard-working trucks. Lemont Truck Center works with coolant-related service and offers Shell Rotella coolant for purchase at the shop.
Whether you need to ask about a coolant replacement, top-up, or purchasing a gallon to keep on hand, our parts counter can help you check the available options.
A/C refrigerant and engine coolant serve different purposes.
If you notice a leak, overheating, or poor A/C performance, tell
our team which symptoms you are experiencing so the correct system
can be checked.
Preventive Maintenance
Why a Coolant Freeze-Point Check Matters
Coolant needs suitable freeze protection for the temperatures your truck may encounter. As described on our previous service page, Lemont Truck Center checks coolant freeze point before A/C recharge or repressurization service.
Ask Our Team
Concerned About Coolant Condition?
If you are unsure about your coolant’s freeze protection or have noticed a coolant leak, ask our technicians about checking the system. Addressing cooling-system concerns can help you avoid leaving a problem unattended.
