Customer Reviews
What our customers are saying

Great people, great service, they care about their customers

Greg L

Great service. Kristen was very responsive with any questions I had and walked through the process with ease. Would recommended Mayhem to anyone. Thank y’all!

Jacob H

Great customer service and knowledge. We will not use anyone else. Very professional and I highly recommend.

John M

This is one of the best small businesses that I have worked with. They are always there when you need them and always willing to go the extra mile. It’s so hard to find a company that you can trust and that will do a great job. If you ever need a quick fix or a complete installation give them a call.

Matthew A

The team at Mayhem was professional, quick and treated us like family! Our air went out in the middle of summer, when we had family in town (of course) and Mayhem came to save us! We will continue to use them and recommend them to anyone who needs HVAC assistance.
