Customer called and said that system wasn’t cooling properly. I checked the condenser for 240V and didn’t get it. I saw that one of the breakers on the outdoor disconnect was tripped. I think it tripped due to a power overload. While I was there, I went into the attic and noticed a lot of air leakage on the return side and a little in the supply side. I recommend we change the return plenum, level the drain pan, seal the coil where it attaches to the supply plenum, put armaflex on p trap, possibly change t stats out for customer. And maybe eliminate the second disconnect outside. System is cooling properly. Warranty Service Work.
