Amazing! They insulated my attic yesterday and it is already 10 degrees cooler overnight. I would highly recommend them for any work. Very professional and cleaned up perfectly.

Nadene C. - Wilton, CA

Very professional and Fast! I called and they were able to fit me in within and hour. The previous company I called could not figure out the reason why a newly installed water heater wasn’t working? Within 30 minutes the technician located the problem. He was very patient and thorough. Taking the time to show us exactly what the problem was. Excellent customer service, caring for the needs of the customer as, (there had been no hot water for over a week!)

K B. - San Jose, CA

Jason and his team were fabulous:
1) Super timely – they got our job in less than a week end-to-end, including permits!
2) Excellent quality – they provide top-of-the-line gear (Mitsubishi) at excellent rates with a super clean installation of our multi-room ductless system.
3) Extremely knowledgeable – they were able to handle a few tricky issues with regards to optimizing the system for our modest power availability and substantial space for heating/cooling.

I recommend J&J with absolute confidence.

David S. - Concord, CA

I am so tired of heat and air repair guys not just fixing the problem and constantly telling me that I need new equipment, j&j heat and air fixed my air conditioners and didn’t push me to replace everything, I’ve known that I needed new equipment but I needed a few more years to get my finances in order. Thank you j&j heat and air for listening to me, making my renters happy, and not costing an arm and leg to get my air cool again. You guys are exactly who I’m calling when I’m ready to replace my equipment.

Carlos R. - Galt, CA

I can recommend J&J Heating & Air without hesitation!! They were easy to work with, clear on every step, went above & beyond in accommodating my schedule and needs, and even helped me get the YGRENE financing squared away. I’m looking forward to being warm during what remains of this winter, cool this coming summer, and having lower energy bills through it all! And having better indoor air quality since they installed the iWave-R Air Purifier into the system!
