For this job I performed a super tune up. I noted oxidized burned flame sensor and ignitor causing flickering when running heat as a potential near future failure. I noted overamprage at start up on the condenser exceding LRA Data tag rating. I also noted extremely low insulation levels. Cooling side of the unit is 5 years old. Homeowner not present, requested email with pictures and estimates. Thank you for choosing comfort experts, have a great day!
