Receiver-Driers and In-Line Filters
The receiver-drier is a service item, not a lifetime part. It gets replaced any time the system is opened — compressor jobs, coil replacement, any repair that exposes the system to air. We stock spin-on and canister driers plus in-line filters for the common bus system brands.
Frequently asked questions
How often should a bus A/C drier be changed?
Any time the system is opened to atmosphere, after any compressor failure, and otherwise roughly every two service seasons. Desiccant saturates quietly; a saturated drier turns moisture into acid inside the loop.
