Preformed single system heating maintenance on a 2025 gas furnace. I tested all electrical components and safeties. All tested within manufacturer specifications. Tempture being supplied to the home was at 116 and 71 return air. Filter size is Aprilaire 410. It does need to be changed, client did not have filters at the time of inspection. I proceeded outside to visually inspected the outside unit. Everything was in good working order. I did notice that the system did not have any type of surge protection. I provided estimates to have surge protection installed. Unit was heating upon departure.
