Today I showed up for an evaluation on the downstairs gas furnace system the AC was not running upon arrival this was due to the float switch being tripped by a clogged drain line cleared the drain line using a shop back down below and nitrogen up in the attic did not cut any pipe installed an antimicrobial pan strip to treat the drain line through the next coming season tested drain line with 5 gallons of hot water after treating with bleach everything is flowing as it should and AC turned back on thank you for choosing comfort experts!
