For this job I performed a super tune-up. I discovered the primary drain line was dry fitted and came loose and also that the drain line does not have a proper p-trap installed. Severe rust and corrosion are present on the drain pan due to water dripping inside of it consistently. I noted mastic seal on the ducts were starting to deteriorate. I recommended a drain line repair and adding a p-trap, resealing the ducts with mastic, and replacing the drain pan. Homeowner agreed to have all work done. Drain line repair was done and partial mastic sealing. Done for now, holding for parts, office to call homeowners when drain pan comes in to install dream pan and finish mastic sealimng. Homeowner requested drain line to be flushed when coming back for rec work, technician agreed to do it complimentary. Thank you for choosing Comfort experts, have a great day!
