Jamar checked the air handler as it was making a strange noise. He said it most likely was doing that because the air filter was very dirty. I changed the filter last night & we could not hear it anymore. While he was here, he checked the system out & all was running ok!
Response from the owner:Louise, thanks for taking the time to share this. I’m glad Jamar was able to pinpoint the likely cause and that changing the filter solved the noise right away. We appreciate you choosing Southern Air, and it’s great to hear everything else checked out and is running well.

Couldn't have asked for a nicer guy. 6/24/25-Jason Klinger Thank you Jason for coming out at night to try and address my 11 year old unit. You did your best and I SO appreciate it. You showed and explained that ...in a nutshell we need a new one. I agree. From last year 2024 ....never hit send DeMare P. was our technician and he was great. After being dropped from the other company that we've had for years (Rhymes with ghertie-they said they weren't reupping contracts in our area...too far). SouthernAir came through for us.

Jamar was polite and efficient. He explained what was happening with my AC and provided a temporary fix for the night. Said he'll be back tomorrow to do a permanent fix. Excellent service!
