Heating tune up Alpharetta Georgia. Tested operation of 2 systems. All components tested within normal manufacturing spec. Discovered upstairs gas line without sediment trap, and with no drain line water safeties which is especially necessary with a water producing furnace in the attic. Downstairs furnace has dirty blower wheel. Systems would greatly benefit from ultraviolet light systems to combat organic and viral growth in systems and throughout the home. Systems heating at this time. Homeowner selling and not interested in repairs
