Professional Residential & Commercial Installation & Repair

Lawrence County Courthouse in Downtown Mt Vernon, MO

Jon Wayne Heating & Air serves residents and businesses across southern Missouri with 2 locations. One of those locations is right at the start of the Ozark Mountain Parkway here in Mt Vernon.

While living in Mt Vernon comes with the wonderful benefit of all this great community has to offer, living in this part of the Midwest also means dealing with more than our fair share of extremely cold winters and extremely hot summers. We know how important it is to have a home HVAC system that works as you need it, year after year. We are proud to be the local community’s trusted company for their heating and cooling needs. We also are Mt Vernon’s installers for generators.


More than a business, we are your neighbors

We don’t just work here. We live here. We have an amazing team of talented technicians and staff who work out of our Mt Vernon location. Stephen Jabro is our Operations Manager.
