"Fast, fairly priced, and they got it right the first time. My Pioneer system was blowing warm air. The tech found the refrigerant line had a pinhole leak at a connection, brazed it properly, and recharged the system. Perfect now."
"My Mitsubishi mini split stopped cooling completely during a brutal heat wave. I called Mini Split Repair Master and they had a technician at my door in under two hours. He found a refrigerant leak, patched it, and recharged the system all same day. Absolute lifesavers in Dundas!"
