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. Adding on, the customer was informed about his coil and blower being really dirty. I offered the customer a full on the clean level 2 which includes, a blower clean, coil clean, duct clean, and microbial mist. Customer rejected and said to wait a couple months for this to be done. Customer also mentioned about a micro air soft start, and that he was interested in it, however he had to wait a couple months to get that done too. Customer said to make a note for whenever he calls they can send technician, to install his soft start. Thank you for choosing Comfort Experts, have a great day!
