Services At O2 Cool Manufacturing
At O2 Cool Manufacturing, we understand the value of keeping you comfortable and productive, so we provide additional services that go beyond handing you a “part in a box.” We can take care of your needs at one of our locations or even come directly to you.

On-Site Training and Installations
At O2 Cool, we don’t just install and send you on your way. We are available for on-site customer services that we tailor according to your specific requirements. We will train your fleet and maintenance crew to operate and maintain our HVAC systems properly.
For special circumstances — if your vehicle is too large or complex to transport easily to one of our facilities, for example — we can come to you on a case-by-case basis.
HVAC Installations
We also offer complete installation, testing, calibration, and fine-tuning services for vehicular heating and cooling systems and other accessories.

Our headquarters in Decatur, TX, is conveniently located on U.S. Route 380 and is where we design and manufacture our systems.
