Dryer Vent Cleaning was preformed with before and after pictures. We preformed heat maintenance on (3 ) 2019 Lennox gas systems. We tested all electrical components and safeties on the inside units. All tested within manufacturer specifications. We did find that on the north side unit had some dust/debris inside the duct work. We then proceeded outside to visually check all of the outdoor units. While inspecting those units we noticed that all three could benefit from having surge protection installed just in case of a lightning strike or possible power surge. Units were heating upon departure. 2 of the units filters need to be changed 20x25x4.
