Mr. Singh & George did a phenomenal job with the installation of our 3-ton central air conditioning along with a Trane condenser. The entire process was extremely pleasant. Will recommend this company for their honesty& empathy for my medical need for air conditioning.

Western Air Mechnaical replaced few of our hvac systems at our office building. All 6 installers that were on job were very professional and very knowledgeable. From picking the right units, pulling permits, working with Western's engineer, scheduling crane for right time, safety walk through, it all was pleasent experience working these professional men.
Behalf of our company, we highly recommend western air mechanical to any office or plant Manager who is looking for a honest and professional company.
