About Our Owners

Owner, Mike Petitt, has over 30 years of experience in the HVAC industry. He started his career working for a large HVAC company, where he worked for 17 years prior to opening Petitt Heating and Cooling with his wife, Trina. Needless to say, Mike has extensive experience as an HVAC Installer, Service Technician and Project Manager. Trina is the brains behind Petitt and the backbone of the company. They have been married for over 26 years and have raised three incredible young men: Austin, Logan, and Brett.

So, what kind of company have they built?

Mike and Trina always had the dream of running a family business where employees could thrive and make a difference in their community. Beginning as a small business based in their home’s bonus room in 2010, they have accomplished just that, now running the thriving company we see today – but they say they have only scratched the surface.

Mike believes that the enemy of greatness is wanting to be just good. When folks in Sumner County hire Petitt Heating and Cooling, they won’t just get a good team that can do the job…they’ll get a team of experts that goes above and beyond. Mike credits his success to God and those he surrounds himself with. From a one-man show in 2010 to employing multiple service techs, install crews, and an incredible office staff, this company has grown to become an esteemed and reputable business in the industry – all led by our Executive Leadership Team: Trina Petitt, Mike Petitt, Chad Harrison, and Ashley Payne.
