    Matt from Coastal Cool Air was fantastic! My car’s air con had completely stopped working and he came out the same day to diagnose the issue. Super professional, explained everything clearly, and had it re-gassed and blowing cold in no time. I also had him look at my dual battery setup for camping, and he gave me great advice on upgrading to a Custom Lithium system. It’s rare to find someone so reliable, friendly, and affordable on the Sunshine Coast. Highly recommend Coastal Cool Air to anyone needing auto air conditioning or electrical work done!
