In Mesa, near East Hope Street and North 24th Street performing a diagnostic on a Bryant condenser. On arrival, customer stated he had another company out over the holiday weekend, and they had found system low on Freon. I performed a leak search on the system and found a lot of oil coming off of the condenser coil. Multiple hits out of the condensing coil from the leak detector. Will call home warranty co. to order a new condensing coil.
