For this job I performed a super tune-up. I mentioned that the primary electrical control unit had burnt weldings on it and were showing signs of a potential future failure. I recommended having it replaced and I also recommended a duct cleaning due to lack of duct cleanings in history. Homeowner stated that they are currently paying off a $12,000 plumber visit that they had and did not commit to having any work done at the moment. I left the estimates as open estimates for homeowner to have as a reference. All the components within the unit were running within normal spec limits. Thank you for choosing Comfort experts, have a great day!
