Preformed single system heating maintenance on a 2025 gas furnace. I tested all electrical components and safeties. All tested within manufacturer specifications. I checked for cleanliness of the duct work and blower wheel. I found the return ducts to be covered in dust. I checked he filter it did not need to be changed at the time of inspection. I then proceeded to the outside unit where I visually inspected the unit. All was in good working order. The unit was cooling upon departure.
