Our Approach

We treat our clients as a priority. We build long standing relationships, and our ability to install or repair anything HVAC related, always exceeds our client’s expectations. We learn who our clients are and remain involved in our community.

Our Story

Precision Air Inc was founded by Stephen after 10 years in the trade repairing, installing and maintaining large commercial HVAC equipment in San Diego. Over the years Stephen observed a lack of workmanship, pride, and skilled technicians in the San Diego area. Precision Air Inc was organized to become the solution to this issue. We assembled a seasoned team of professionals that have all been in the trade for 10 or more years. The team makes customer service our top priority and with our extensive experience the company quickly grew. Our staff of trade professionals are skilled in installing data room precision cooling systems, surgical rooms, clean rooms, manufacturing facilities, industrial process cooling, commercial office comfort cooling, and residential homes systems.

Meet the Team

Here we are! We are the ones that are working before the sun comes up, and after the sun goes down to keep you comfortable and your businesses’ operating whether it’s hot or cool outside.

I have knowledge of all things construction; electrical, plumbing, framing, roofing, flooring, remodeling & more. Teaching others about my knowledge is something I have a passion for as I sincerely love my job & always try to have fun. On the weekends I enjoy playing Pokemon with my son and spending time with my beautiful wife and daughter.
