Great technician, office didn't follow up at all
Jill - O'Fallon, MO
I called at 7:30 a.m. and was told they would be out late afternoon. Called at 3:30 to check the time and was told 5-5:30, called at 6:45 and was switched to night service, which they sent a overtime tech out, didn't charge me but had a bit of confusion re that. I felt like i should have received some kind of call if they werent going to make it out that evening. I had to be the one to call the emergency line to get a technician out there. Not sure when they planned on getting to me?... The service tech was super nice!
Great Service, Awesome Price!"
Bill - O'Fallon, MO
My tech, Sean, was very thorough and showed me what was wrong with the air conditioner and how much it would cost to repair it. I would recommend Classic Aire via the Home Depot for any other HVAC service.
Quick and efficient service

Jeff - O'Fallon, MO
I thought John did a very thorough job of going thru and determining that my A/C system was working properly. Over the years I have observed many folks that do what John does and it was very evident to me that John is really good at what he does. He was very courteous and was done and gone in very quick order.
