Light Commercial HVAC Service in Kingfisher, Oklahoma
When your restaurant cooler quits during dinner rush or your retail storefront hits 85 degrees in July, you need someone who picks up the phone. I service light commercial HVAC across Kingfisher County and Central Oklahoma. Same Master HVAC license, same 45-year career, same honest pricing as residential. Just bigger units and faster response when downtime costs you money.
4.8 stars / 279 reviews. Master HVAC License. Same-day available on commercial emergencies.
Light Commercial Clients I Service
- Restaurants, bars, cafes (walk-in cooler plus dining HVAC)
- Retail storefronts and small showrooms
- Small offices and co-working spaces
- Churches and community halls
- Daycares and private schools
- Salons, spas, barber shops
- Small manufacturing and light industrial (under 10 ton)

If your facility runs under 25 ton total cooling load and isn’t a heavy industrial process site, I can probably help. Ask me first instead of waiting for a “we don’t do commercial” answer from your residential guy.

Frequently Asked Questions
How fast can you respond to a commercial HVAC emergency in Kingfisher Oklahoma?
Same-day is the goal. I prioritize commercial down calls over routine residential. Call 405-375-4822 and say it’s commercial. Inside Kingfisher County, response typically runs 60 to 120 minutes during business hours.
Do you service walk-in coolers and freezers?
Yes. Compressor failures, refrigerant leaks, coil icing, defrost issues, controller problems, door gaskets. R-404A and R-448A routine. New install quoted custom to box size and load.
What’s the difference between residential and light commercial HVAC?
Bigger tonnage, three-phase power, different refrigerant management, tighter response expectations. Light commercial is 3 to 25 ton single-unit, often packaged rooftop. Heavy industrial process cooling is outside my scope.
Do you offer commercial maintenance contracts?
Yes. Custom contracts sized to your equipment count and building hours. Most sites get spring and fall visits covering coils, refrigerant, belts, filters, controls, and condensate. Ask for a quote.
How much does a rooftop unit (RTU) replacement cost?
5 ton straight-cool RTU typically $9,000 to $14,000 installed. 10 ton $15,000 to $22,000. High-efficiency or economizer-equipped adds 15 to 25 percent. Free estimate, custom quote, no hidden fees.
Commercial HVAC down? Let’s get you back up.
Restaurant, retail, office, church, daycare, salon, small shop. I service it all across Kingfisher County and Central Oklahoma. Same-day available on emergencies.
