OK, but…
August 20, 2025The system is cooling fine but has made a groaning sound since installed on July 18. The A/C tech determined it to be an issue with the air handler motor and ordered a replacement through the warranty which has yet to be delivered. This delay does not make me hopeful for any future issues that may arise.
