Preformed single system heating maintenance on a 2018 gas system. I tested all electrical components and safeties. All tested within manufacturer specifications. Temperature being supplied to the home was 118 and 73 return air. Filter had recently been changed, 20x25x4. Provided estimate to have Aprilaire conversion kit installed to upgrade their filtration system. I proceeded outside where I visually inspected the outside unit. All was in good working order. Unit was heating upon departure.
