These parts are built to handle the demanding conditions of Class 8 trucks and keep your climate system performing at full capacity.

Frequently asked questions about A/C components

What does the receiver drier do in a truck A/C system?

The receiver drier removes moisture and debris from the refrigerant before it enters the expansion valve. Moisture in the system can freeze and create blockages, while contaminants can damage the compressor. It's recommended to replace the receiver drier any time the A/C system is opened for major service.

How do I know if my evaporator core is failing?

Signs of a failing evaporator core include weak airflow from the vents, a musty odor inside the cab, and pooling water on the passenger-side floor. In some cases you may also notice the A/C system cycling on and off rapidly. A refrigerant pressure test can confirm whether the evaporator is leaking.

Should I replace A/C O-rings and seals when installing a new component?

Yes. Any time you disconnect a refrigerant line or replace a component, you should install new O-rings and seals. Old seals lose their flexibility over time and are a common source of refrigerant leaks after a repair. Use O-rings rated for the specific refrigerant type in your system.
