Equipped to assist in the annual cleaning of outdoor residential or light commercial air conditioning or heat pump coils is the TriClean 2x coil cleaner. It is designed with an integrated sprayer that allows the user to connect to a hose, clean, and rinse.
The relationship between high-performance air conditioning and refrigeration (ACR) sealants and moisture is similar to a dysfunctional marriage. ACR leak sealants can’t live with moisture and they can’t live without moisture.
A hot topic in the world of refrigeration and air conditioning continues to swirl around refrigerants and what refrigerants will take hold and be used now, besides HFCs, and what will supplant HFCs in the future.

Amidst all the talk about refrigerants such as HCs, HFOs, and CO2, the vast majority of contractors are still working on HFC and HCFC systems. With that in mind, Winnipeg, Manitoba, Canada, contractor Brian Baker of Custom Vac Ltd., offers some perspectives on the familiar refrigerants of R-410A and R-22.
