Had Rodel come for yearly HVAC maintenance. Was very friendly and knowledge-able. He was efficient and talked me through all the readings and findings of my Furnace and AC unit. They have a very transparent and understandable system which is appreciated.
I like the service and job but just one request I have here: please make sure if you are doing a maintenance , repairs or replacement let the technician / plumber use it first in front of the customer to make sure everything is working right. Many time I have plumber / hvac technicians walk away without checking…
Jose was excellent and we are so pleased for his working attitude and trying to think for his customer. He made us feel confident about Jazz services overall.
I had Jose perform AC pre-summer check up. He was outstanding!! Very friendly, knowledgeable and professional. He should receive a 5 for his service.

I’ve been using Jazz for my HVAC needs for my house in Bay Point. They’ve done repairs on my existing system, and I signed up for their monthly service plan. Today their employee Ridge came out and was a wealth of knowledge and a pleasure to have at my home and tube things up for me. Highly recommend
Rodel was so sweet and extremely formative. Appreciate all that he did and his patience with my insane household.

I called Jazz out for a quote to get a sewer lateral pipe replacement and main water line replacement as my home is on the older side. Monty came out and ran a camera down the sewer pipe to show the condition and get measurements. He mentioned that a trenchless replacement was an option. He was professional,…

John M. Came by this time to test my plumbing and flush my tankless water heater. Everything was great.

Overall he did a great job, immediately put on protection on his shoes before walking in the house, which…
Said was very knowledgeable and helpful. Cleaned up and explained everything to me. Will use Jazz again when I need HVAC help.
Isaac did a great job servicing our residential HVAC system. He cleaned the outdoor AC from a year’s worth of dirt and leaves, and thoroughly inspected the AC and furnace, identifying potential wear and tear. We signed up for the Jazz maintenance program to make sure the units and filters are regularly cleaned and inspected.
I couldn’t be happier with the service Josh Simangan provides. Josh arrived on time, was professional, and thoroughly inspected and serviced my system. He explained everything clearly, cleaned the unit, checked all the components, and made sure it was running efficiently before leaving. I really appreciated his…
