Florida Heat!
August 31, 2025Installed new AC/ Lennox after my 20 year old Carrier couldn’t keep up with the Florida heat. Expected a lot from Lennox but at first it wasn’t keeping up either. Fixed part of the problem, roofers when installing new roof covered over the gap to release heat through ridge vent. Now that that’s fixed it’s working a lot better but still has days when the heat is too much and it can’t keep up. Also thought it would help keep the humidity down but I still need to use the dehumidifier! Overall it’s working and I hope I get 20 years out of this one.
