For this job, I work on a super tune-up on this gas furnace system. I went through all the mechanical and electrical parts of the system and checked for maximum efficiency. A pan strip and a drain switch we're recommended for the unit, to prevent clogs, customer rejected and mentioned he would probably do it next visit. I compressor saver or a micro airsoft start was also recommended for his unit, customer rejected. Thank you for choosing Comfort experts, have a great day!
