Preformed single system heat maintenance on a 2019 gas furnace. I tested all electrical components and safeties on the inside unit. All tested within manufacturer specifications. Temperature being supplied to the home during heating was at 116 degrees and the return temperature to the unit was at 67 degrees. The air advice report came back with some concern areas. These area of concerns could be addressed by having the ducts cleaned. I did notice that the unit didn’t have any surge protection on either 5e inside unit or the outside unit. I left estimates for full system surge protection to be added onto the unit. Also left estimatmfor a level 1 duct cleaning. System was heating upon departure.
