J&J is second to none! They deserve a million stars! They are the best in the bay! Owner Jerry Hurwitz, General Manager, James Sandoval, Frank Quintanar Service Manager and Ed Chan Construction manager and their awesome teams saved our family home after a fire!! J&J Air cares about their customers and their safety is priority one. They made sure we will have a clean environment and did magic on our home. James Sandoval made sure my insurance company understood the necessity of replacing all my duct work and specially engineered an amazing unit so we didn't live in a toxic environment

Our company had been having some AC issues and we were tired of the misdiagnosis of other companies who came ill prepared and assumed we didn't know to set the thermostat.
J&J Air came and within a short time identified the issue that other companies had missed. He then notified us of the issue and scheduled to come the next day with parts to fix the issue.
Don't be fouled by low quotes and multiple bills from other companies. Get your AC fixed right the first time. In the end these "lower cost" companies cost you more. Both in numerous bills and wasted time.

We have had J&J air several times over the past year to our business and our system has NEVER worked completely. They come out and fix a problem and then a week later something else goes wrong. The heat and A/C in our business has only worked periodically and we have spent over $5000 with nothing to show for it. They always say it is a new problem and ALWAYS charge us for coming out. NEVER USING THEM AGAIN

I have had a bad experience with J&J Air. First, they are always late, and not on time. I have to change my work schedule to meet them so they can fix/repair my AC/Heating unit. The owner (Jerry Hurwitz) has over billed me a few times, that is fraud. Plus trying to over sell me on products/materials. I have reported them to the Santa Clara County BBB & State Department Consumer Affairs for there unethical business dealings! Stay away from J&J Air & Owner "Jerry Hurwitz", it will be the BEST thing you can ever do, save yourself the headaches!!

Used this company and felt the repairs were very pricey. I complained several times. When I called for service they cancelled!
