For this job I performed a evaluation. Homeowners stated that it did not seem to be cooling efficiently upstairs. Homeowner stated that we have added refrigerant in the past a couple years ago but did not address where the leak was from. I like search the evaporator coil and got a few hits from the leak detector. The Delta and subcool were both very low. I spoke with home owner about replacing the evaporator coil, clearing their drain line that they wanted done, and adding refrigerant vs a complete system replacement. Homeowners opted to have a comfort advisor give them an estimate for a system replacement. Comfort advisor scheduled for 7/15/25 between 3 and 6. Thank you for choosing comfort experts, have a great day!
