Preformed maintenance on a single system gas furnace 2008. I tested all electrical components and safeties. All tested within manufacturer specifications. I did find that the blower wheel was dirty. I offered a blower wheel pull and clean customer elected to have it cleaned today. Temperature being supplied to the house was at 127 and 76 on return. Unit was cooling upon departure. REMOVE AND CLEAN BLOWER ASSEMBLY LEVEL 1 A BLOWER ASSEMBLY MOVES AIR THROUGH YOUR SYSTEM. IF DIRTY, THE ASSEMBLY BLOWS THAT DIRT INTO YOUR SYSTEM. THIS CAN LEAD TO HIGHER ENERGY COSTS, ODORS AND DAMAGE TO THE UNIT.
