Upon arrival, I found that there was water on the floor of the basement under and next to the unit. I found that the drain line coming from the AC coil was clogged. I cleaned the line out with cleaner and put a drain pan tablet in the pan. The client wanted me to do a maintenance on all of their equipment.

Furnace PM. Everything went great. We replaced the two burners. Check combustion and gas leaks after. All set. Thank you!

Today I completed an AC PM. Everything went great. Please see the sheet for details of today service. When cleaning the outdoor unit, I noticed the water pressure to be high. I checked it with a gauge and it is over 100 psi. You need to have a pressure reducing valve installed. I also looked into the zoning issue with upstairs. I disassembled the first floor damper and found when it was shut that it wasnt closing all of the way. I adjusted it so that it was fully closing when it was supposed to be. I have also sent an estimate to replace the two nest thermostats with ecobees or the Amazon ones that you had mentioned. Thank you!

Today I performed a maintenance on the minisplit system and the central air conditioning system as part of your GSMS Homeclub. The minisplit system checked out great. I vacuumed and washed the filters. I washed the indoor coils as well as tested operation. The central air conditioning system was in much need of a maintenance. I found the capacitor outside to be out of spec. I replaced it. I also needed to add 1.5 pounds of refrigerant to the system. I also added the leak sealant with dye to try and stop the leak. Sometimes it works! Thank you! Please see maintenance form.
