What customers say
"My wife and I have a park model and the current AC and hest setup was from 1989. As we just moved in we didn't want to make a big replacement but it was necessary. We contacted AC by J and they have is a GREAT price and the customer service. Julie in the office was wonderful and out installers Zach and Charlie did a wonderful job. The initial 2 ton system turned out to be too wide but they took it back out (in & out…"
— Scott Freburg · Nov 20, 2024 · Google Reviews"Richard came out to do a tune up on our AC unit in September. He was prompt and thorough. What I appreciated most is that he was very clear with his explanations of what the service options were and what the benefits and risks were. He did not try to upsell and was extremely professional. I would highly recommend Richard Cordova and AC by J."

— John Thompson · Oct 28, 2025 · Google Reviews"Brandon was awesome! I was dealing with a time crunch and he got the work done quickly and efficiently. He is also very friendly and eased all of my concerns by completing the valve replacement in less than an hour."
— Michael U. · Oct 29, 2025 · Google Reviews"Was happy with AC by J but now after the merger the service is awful. They will not honor warranty work. There is no live person to speak with only a machine. This is what happens when a company makes a bad business decision and doesn’t consider the downside of their decision . I will need to find a new company for AC and plumbing needs. Too bad we were good customers."
