Josh Simangan was comprehensive and did a great job servicing our HVAC system.
Our HVAC system was due for routine maintenance. The visit was at no cost to us, as the system was installed last year. Our technician, Josh Simangan, explained everything he was going to do and answered all of our questions pleasantly and completely. We’ve used Jazz for plumbing repairs also, and we were very…
Ridge from hvac did a great job finding out why my outdoor unit is not working and fixed the fuse right away! Cant recommend these guys enough
HUGE shoutout to Sammy!!! Our A/C went out during a heatwave, and I thought we were going to be without air for a while. I went to Home Depot and happened to run into a Home Depot manager and Jazz rep, and they offered to come out and check out our broken A/C that same day. Sammy came out to took a look. He needed…
Joshua simangan is a professional technician with great knowledge and manners I would like him to be my technician every time .
Manuel helped us with a new install and came right away when we had a concern. Working with Manuel has been a pleasure and he’s an asset to the Jazz team. Great experience.
Never hire this dishonest air conditioning company for either installation or repair. I learned a painful lesson from their experience installing and repairing my entire air conditioning unit. They violated their contract by using a cheap evaporator coil installed in my attic, out of my sight. Six years later, it…

Josh came out to service my HVAC and air conditioning units. He was very thorough and professional. After the service he explained everything he did in plain English and gave me a summary of the condition of my systems. I would highly recommend Josh Simmangun to all my friends.
Sammy did a great thorough job! Great customer service and very friendly! He explained everything in detail of what he did and his recommendations. He took lots of good pictures of everything. I would definitely call him back for work as needed. I highly recommend him! Thank you Sammy! Be blessed.
Rodel was so sweet and extremely formative. Appreciate all that he did and his patience with my insane household.

AS Brandon was a very professional and knowledgeable representative of Jazz. Came in with the shoe booties and had all sorts of knowledge about what I should expect with this AC system. I appreciate his service and will recommend and use them again when needed.

Joshua Simangan demonstrated exceptional expertise and a deep understanding of his field. He clearly explained how the AC system works and identified the issue with precision.
