Before you call, walk through a few quick checks we use ourselves. Sometimes the fix is a tripped breaker or a closed vent. If it's not, we'll get a truck moving.

Real reviews from real jobs
"Okie HVAC - Dylan and Dean are awesome! They were out here killing it in this 100 degree weather to replace 2 outside units. These guys are knowledgeable and do a great job. Thank you gentlemen!!"
"OKIE HVAC came and bid on a new HVAC system for me. They were there when they said they would be and were very friendly and polite. They took the time to explain in detail how much the project would cost as well as what would take place during the install. After installation I even had the opportunity to stop by the OKIE office for payment and Paige made you feel just like family! Seeing how the employees interacted with her I was impressed with not only her professionalism but the family atmosphere in the office! Thanks OKIE!"
