AJ Heating and Colling was outstanding. I needed to install new ducting, air conditioners and heaters. Jose is the owner but manages the installation and follow up. His team was nothing less than outstanding. At the very beginning, Jose would promptly respond to my e-mails and willing to change the design. I found many other contractors wanted to just install the furnace and air conditioner. They avoided getting involve in new ducting work. Jose’s team does both. He also has excellent follow up. There was a heating vent that required a new register. Some contractors would not follow-up after the installation, but Jose’s team came back three times to get the right size. Jose addressed all my concerns during the installation. I was impressed by the level of workmanship during the installation. I would highly recommend Jose to anybody interested in new ducting, heating, and air conditioning.

My uncle told me to call this company to fix our heater and they came to our home and fixed the problem very quick. Everyone was so nice and my uncle turned out to be very happy and that why Im writing this review. He wants everyone to know they are very nice people.

Jose diagnosed our broken AC on the hottest day of the year. Another guy the day before tried telling me wed have to replace the whole unit ($6k+). Glad Jose figured it out for a few hundred... Definitely knows his stuff and the system is working great now.

If you want the very best of the best in heating and air conditioning, look no further than AJ Heating and Cooling. They are truly elite in this industry. Jose (the owner) does the most impeccable work I have ever seen! He is professional, honest and stands behind his work with integrity and pride. We have had AJ Heating and Cooling do installation and service work for us personally and with both we were beyond impressed. We also do state required testing on his work as we own our own HERS company and in all the testing we do on a daily basis for HVAC contractors around the Bay Area, we have never seen better work from any other contractor. His work is clean and his ductwork is sealed to standards that are far above state requirements. We are and have always been truly impressed with the work that AJ Heating and Cooling has performed. You will not regret using them for any HVAC work in your home! They are truly amazing!
