Denny recently cleaned our A/C condensing unit and did a solid job. He also previously installed our heating, A/C, and venting system, which has been working well for us over the years. He recommended and installed high quality equipment. We appreciated his help with these projects and will definitely use his services in the future.

Denny is amazing. Fair and professional. Highly recommend him and his services.

NorCal comfort Pros did a great job putting in our furnace thank you so much guys

NorCal Comfort Pros did a wonderful job installing an AC system. They were very knowledgeable and their prices were very reasonable. I would highly recommend NorCal comfort Pros for any HVAC work.

NorCal Comfort Pros did a great job replacing my old worn out furnace with a brand new heat pump at my home in Cupertino! They gave us a great price and was able to schedule our job quickly, while another company we spoke with did not have any availability for 3 weeks. Time is important when the family is cold :)

Our AC broke down during last week’s heat wave in San Jose. Denny came in the same day and diagnosed the problem.The replacement motor was coming in 2 days. But Denny went to a nearby store to bring the part and fix our AC the next day.Amazing professionalism!Would highly recommend him.

Denny did a thoroughly professional job for my project. His knowledge and expertise provided truly great results.

I really appreciated that Denny dose all the work himself, instead of hiring someone else to perform the work. Great quality installation.

Denny replaced our AC unit and I would recommend him all day. He scoped out the project, made suggestions and offered options, gave us a quote and delivered on the project on schedule. Great guy and knows his stuff!!!

Denny has worked on a couple of my houses. He has installed full systems and trouble shooted problems. I only use honest guys that are going to stand behind there work. I won't go anywhere else for heating and air!!!

Dennys heating and cooling is severely underrated. He got us a great price and was finished in just a couple days. I would highly recommend this service

Denny installed a complete HVAC system in my home. He did an excellent job installing it. He is kind, courteous, and professional. He was careful to keep my house clean and not create much construction debris. He cleaned up as he worked. I am very impressed with his work. My system runs great. Heat and air. I reccomend him to my family and friends. It is refreshing to find a contractor these days that does a great job, that is respectful and professional, and value.

I was amazed on how fast he took care of problem, moving forward i will call him only to do our service……!Thank you Denny’s Heating and cooling
