We have received excellent service from John's Heating and Air. After a strong recommendation from a family friend, we called John's for a regular service request, and we were very pleased with the attention and dedication to resolving the issue. When we had to replace the system, John's provided great pricing and exceptional, timely installation. Again, we are very pleased with this company and looking forward to continuing our working relationship with them.

John and his crew have serviced my a/c for several years now. And when it was time to replace and upgrade my unit, they were fast and efficient. Everyone I've had contact with at this company has been kind and courteous. Excellent service and courteous crew! Most definitely will recommend them.

I sent them a message on their site on a Sunday evening about my upstairs AC that died. Early Monday morning they had a couple of guys all bright eyed and bushy tailed at my door and fixed it lickity split, before I had even finished rubbing all my eye boogers out.

Sent them a msg on their site on a Sunday evening for my busted upstairs AC, they were here first thing the next day and had my AC up and running within an hour. I've never had service this fast for anything since I moved here.
