“Our experience with Brad, Joe and Sway this weekend at O2Kool was top notch quality. Brad's knowledge and professionalism was what stood out and replacing our entire old system due to age (R-22) was completed quickly and competently.”
“02Kool are the best! They have looked after our airconditioning unit for a number of years. They have always been fair, reliable and they get the job done quickly! I have now replaced two aging units with them and they come support them, no questions asked! I could not recommend them more highly.”
“First of all I love how this place is open 24/7. Our AC was not working and it was really hot in our house. We called 2Kool and they sent Brad to our residence that same day. He was fast, and knew exactly what to do.”
“This company works 24/7 which is awesome. Our AC wasn't putting out any cold air. Called O2Kool, they sent out their technician Brad. He assessed the problem very quickly, and knew what caused it. Had us back and running in no time same day.”
“I had my AC quit on a 100°F+ day and Brad was able to come out within a couple hours for an after hours fix. Brad quickly diagnosed and repaired the issue for a good price. Brad was very friendly and explained exactly what was broken. I plan to use O2 Kool when I need a full HVAC replacement as well. Thanks Brad!”
“I had the most amazing experience with O2Kool! It was Friday night at 6 and we realized our unit was not cooling properly. I found these guys online. I called in a panic. They sent Brad over THAT NIGHT! He inspected our whole system and got us up and running.”
“One of the A/C units in our rec room at Edgewater Resort in Buchanan Dam quit working late today. Spent quite a bit of time trying to find someone available to check it out for us. O2Kool is open 24 hours, and they responded right away. Brad swooped in and saved the day.”
“Chris came out to service my parents' AC unit that wasn't working. He found the ants that were in the unit, cleaned them out and got the AC running. The amazing thing is he did not charge them anything for his time and service. Great company and good people! Would definitely use them again.”

Let’s Clear the Air
Why is my AC blowing warm air?
Warm air usually points to low refrigerant, airflow restrictions, thermostat issues, or a failing compressor. O2 Kool diagnoses the root cause and handles emergency repairs when Kingsland homes can't wait.
How often should I service my air conditioning unit?
Most homes should schedule professional AC maintenance once a year before peak summer heat. Annual service helps catch small issues early, improves efficiency, and can extend equipment life.
Do you offer warranties or guarantees on your work?
Yes. O2 Kool backs its work with a customer satisfaction guarantee and clear, upfront pricing before service begins.
Do you offer financing options?
Yes. O2 Kool offers financing options through Wells Fargo and Synchrony so homeowners can spread out larger HVAC replacement or repair costs. View financing options →
