Report
We had an HVAC system installed in our new home build by Ken Maddox in 2014. I called to have them come out for maintenance on the system and was informed that we are no longer in their service area and I should Google search to find another business who would come take a look for us. If I was asking for a new system installation, I could accept this response. But to me it's very disappointing and unprofessional that a business doesn't stand behind their product and assist a past customer on a system that they installed.

Wish I could give zero stars. I have a new home construction, I have leaking exhaust flues that's acidic and ate away my Vinyl flooring. Every gas fitting is leaking and has no pipe dope. The entire duct system is undersized. The workers that installed my system had their kid in my home running around. The "installers" and kids were all in pajama pants. Currently have been waiting 5 hrs with no call back from a "service tech" what clowns this business has.

I have used Ken Maddox for 19 years they put my HVAC system in when we built the house. Long story short I will advise people not to use this do to poor customer service. I scheduled a service cleaning a few weeks ago do to it be hard to take time off work. I got a call a day before the scheduled appointment stating that they need to reschedule and the next available appointment is 10-12 days out.
Over the past few years I have noticed a decline in their customer service. The lady that called was extremely rude and when I asked to talk to someone over her she hung up on me. Needless to say I went with another company which got me right in. Williams Comfort and air thanks.

Technician Mike (with the mustache) is awesome he has never failed to take care of me. He has went out of his way multiple times to help my family and I stay comfortable. Always professional, thorough and very knowledgeable. Wish I could say the same about other installers/technicians at Ken Maddox. He deserves a raise for all of his expectational service he's always given us. You need more technicians like him! Thanks for everything Mike! -Codie
