Aluminum Line Repairs
The Mechanic’s Choice
We accept referral and sublet AC work from general repair shops in Concord and Vaughan. We provide the technical results that dealerships charge double for.
Why Concord Drivers Trust Radman
Nitrogen Pressure Diagnostic
Dyes and vacuum tests fail to simulate real-world pressure. We use high-pressure nitrogen to find pinpoint leaks in evaporators and condensers instantly.
R-1234yf Systems
Most 2018+ vehicles require the new R-1234yf refrigerant. Our shop is fully equipped with the precise recovery machines needed for these modern, high-efficiency units.
Aluminum Line Fixes
Instead of replacing entire dealer assemblies, we perform sectional line repairs. It’s the professional way to save hundreds on rusted A/C lines.
