Today I performed a super tune-up for a current member checked everything indoor and outdoor and heat mode and in cool mode mechanically everything appears to be functioning as it should wash the outdoor coils changed the filter flush the drain line with white vinegar I have several concerns however they all have to do with airflow/air quality therefore I have offered the homeowner a complimentary visit with our airflow/airquality specialist Zach and while the homeowner agrees to the visit he is unsure as to his schedule and what would work for him and his wife so we will have to follow up with him or wait for him to call back currently their AC / heater is dumping air into the Attic and that coupled with the biological growth I found on the blower wheel should really be addressed as soon as possible thank you for choosing comfort experts!
