For over 30 years, OTEK has provided dependable HVAC services built on quality workmanship, integrity, and exceptional customer service. Founded in Los Angeles, California, in 1989, we began residential HVAC before expanding our expertise into commercial, industrial, and in process cooling systems.

In 2021, we opened our Arizona office to better serve businesses throughout the state. Today, we proudly support office buildings, retail centers, warehouses, and manufacturing facilities. Healthcare providers, educational campuses, data centers, and other commercial properties with reliable HVAC services.

As a family-owned operated company, we believe in doing business the right way. We don’t employ commission salespeople – we employ experienced HVAC professionals who provide honest recommendations, dependable workmanship, and responsive service you can trust. 

At OTEK our mission is simple: to keep your facility operating efficiently with reliable HVAC services, fast response times, and long-term customer partnerships build on trust.
