About

We service all aspects of heating, air conditioning, and refrigeration installation, maintenance, and repair. And we specialize in absorption chillers.

Welcome to Liberty Air, HVAC Specialists! We are located in Encinitas, California, which is in North County of San Diego. We work mostly here in Southern California, but with my rare expertise with absorption chillers, I get requests to service customers all over the world.

I have 15 years of experience working with the air conditioning and refrigeration union, and 10 years of experience as an authorized service agent for Thermax Inc. This includes 19 years of experience working on absorption chillers.

I now run Liberty Air, and service all aspects of heating, air conditioning, and refrigeration. We’re not a huge company, but we give individualized service and when you call Liberty Air you’ll be talking to me directly. I live here in Encinitas, with my beautiful wife, Debbie. We look forward to hearing from you soon.

Thank you for visiting Liberty Air!
