FAQ'S

What is the function of a drier in an AC system?
The drier (or receiver/drier) removes moisture and contaminants from the refrigerant, protecting the system from corrosion, ice formation, and component damage.

How does an evaporator work in a heavy-duty vehicle’s AC system?
The evaporator absorbs heat from cabin air by evaporating the refrigerant inside its coils, turning it from liquid to gas and cooling the air before it’s blown into the cab.

How do I know when a drier or evaporator needs replacement?
Signs include reduced cooling performance, musty odors, refrigerant leaks, icing, or corrosion. If system repairs are done (e.g. compressor or lines), replacing the drier is recommended to ensure clean operation.

Are your driers and evaporators compatible with major truck brands?
Yes — our selection includes models engineered for heavy-duty brands such as Freightliner, Kenworth, Peterbilt, Volvo, and International, aligning with OEM specifications for proper fit and performance.

Do I need to vacuum or recharge after replacing a drier or evaporator?
Absolutely. After replacement, the AC system must be evacuated (vacuumed) to remove air and moisture, then recharged to the correct refrigerant specification to ensure full cooling capacity and longevity.
