Commercial Cooling

When your business's cooling system goes down, downtime is not just an inconvenience—it is lost revenue. Jon-Wayne Company has provided commercial HVAC service to Mount Vernon and Northeast Texas businesses since 1983, and we have built our reputation on the same standard your customers hold you to: show up, do the job right, and stand behind it. Call (903) 537-4531 and reach a locally based, licensed team.

We are a Carrier Authorized Dealer, TDLR-licensed (TACLA024747C), and A+ rated with the Better Business Bureau (BBB). We repair and service all makes and models of commercial heating and cooling equipment—rooftop units, indoor systems, and everything between—and we believe a business owner deserves a straight answer about what their system actually needs, not an upsell. Your focus belongs on running your business; ours is ensuring the building stays comfortable while you do it.

Air Conditioner Repair

Don’t let your coworkers or employees suffer through another day in a hot, stuffy workplace! Is your company’s air conditioner acting up, freezing up, or making too much noise?

Our experienced team of HVAC professionals is here to keep your company cool. We repair all makes and models, rooftop and indoor units, and we will never try to sell you a service you don’t need. Our technicians are honest and hard working, and we’re always transparent and fair about the work we do.

Air Conditioner Replacement

In your business, oftentimes you need to look at the bigger picture. Our professionals do that as well. Sometimes a repair is not sufficient to fix your air conditioner. Sometimes a new air conditioner is the most cost-effective and energy-efficient way to go. Even though it may be a little more expensive up front, it’s an investment in your company.

With a new system, you will actually be spending less in energy and cooling costs. We will always be honest with you about whether replacing your air conditioner makes sense. We value our time and your money—we don’t want to perform repairs or service on an appliance that is in need of replacement.

If your company does need an air conditioner replacement, we know that your attention needs to be on your business, so let us help you with the air conditioner information and details.
