Spray Foam Insulation in Chico, CA

We had Royal Aire install central heating and air conditioning in our home. Russ and his team were professional, efficient, and personal. They were patient with us when we asked questions, and were quick to address any concerns we had. The system they installed works like a champ, and we really couldn’t be happier with the whole experience. We accessed Royal Aire through Costco’s program, and would do it again the same way.

Richard did a great job of assessing the problem with our ventilation system and recommending immediate action. He requested other staff to come to my house immediately to repair the exhaust system. He also signed me up immediately for the Royal Gold Plan and immediately provided me with my first maintenance service. He did a great job and I would like to request him to return in the future for the next service.

My technician Nick was prompt and thorough always doing the extra in anwering questions. During my visit an unkown problem was discovered, he showed me explained what needs to be done and the.price. I am very happy with the service and company.

Diaz Insulation was great to work with and reasonably priced. I had the crew come out and remove the old insulation I had in my attic, which has a very small crawlspace. Then, I had the crew come back a couple weeks later and blow in new insulation. They answered all questions I had, the crew was professional and cleaned up after the work was complete, and the job itself was done very well. Thank you for a job well done!

I highly recommend Diaz Insulation. A professional team from the first call to project completion. Prompt, professional, easy to work with, and friendly. It was a pleasure to work with this team. Roy Diaz came out within a couple of days of a call to ask for a bid from them. He was very professional, offered options to box in my whole house fan, recommended and explained different R-values for my home and garage, and I most appreciated his recommendation to upgrade any electrical that I may need in the future before they blow in the insulation. Once I gave them the call that I was ready for them, they were out the next day, and their installation team was prompt, professional, and courteous.

Diaz Insulation cleaned my crawlspace and removed all the insulation. Rodents compromised the insulation for years. I tried doing this job myself and it was too difficult. They did a thorough job and I'm very happy with the outcome. Great Job!
