For the evaluation I showed up to the customer's home she stated her air conditioning was only blowing out hot air. When I went upstairs I immediately noticed there was water in the overflow pan when I opened up the air handler the coil was frozen. I turn on the heat try and let it start to thaw out, and gauged up outside showing a saturation temp of below 10⁰F. I like searched the air handler and believe the leak is coming on the underside of the Evap coil. I charged the unit to the appropriate superheat to hopefully get the customer by until the new coil is ordered and we can install it.
