 Trustindex verifies that the original source of the review is Google. Javier has been helping me with my HVAC system for about six years and has always been professional and done great job. He has repaired my old system and kept it running for as long as possible, and then installed a new unit when the original finally broke down beyond repair. His rates are always reasonable and his work is always excellent. He goes above and beyond. Will continue to work with him whenever the need arises.

 Trustindex verifies that the original source of the review is Google. Javier showed up to the house on the same day I called. He did a tune up for free and discovered that my refrigerant was low and the filter clogged. He consciously made an effort to not find erroneous problems. He took photos and showed me model specifications on my unit to make me comfortable with his assessments. I highly recommend JZ AC Service. His honesty is above reproach.

 Trustindex verifies that the original source of the review is Google. Javier just repaired my A/C! I'm so happy! My A/C unit is pretty old, but he was still able to get it running again. He didn't just try to upsell. Javier is very nice and easy to work with. He was prompt with communication. I think he was fair and honest. I wouldn't hesitate to call on him again. Thanks, Javier!

 Trustindex verifies that the original source of the review is Google. After 1.5 years of trying to get the AC guy I'd been using for 5+ years to quote and replace new units in my home, I'd given up and started looking for another person to do the job. My biggest concern was finding someone who would be honest and reasonable and I found that in Javier. I originally found his recommendation on Reddit and I'm so glad we went with him to do the job. He was thorough in explaining the current state of our units and our options in having them replaced. Do not hesitate in using him!
