A Decade of Comfort Solutions
Simms Refrigeration & Repair was founded with a simple mission: provide honest, reliable HVAC services that Southwest Oklahoma residents can depend on. What started as a small service call business has grown into a full-service heating and cooling company serving multiple counties.
We believe that everyone deserves a comfortable home, regardless of the weather outside. That's why we treat every job—no matter how big or small—with the same level of care and attention to detail. Our technicians aren't just skilled workers; they're neighbors who understand the unique climate challenges of our region.
