"Personnel were friendly, explained clearly how the system would work. Showed up on time and completed the work as promised."

"Junior was totally on top of things. Installers were on time, polite and very efficient. I was given 5 quotes from other companies but General Air Technology was BY FAR the lowest quote."

"They finished the job quickly and all is well. They were terrific."

"Jim's Air Systems had the best value for my dollar. They supplied me with better equipment than they quoted for the same price. They completed the entire installation in about five hours. They protected my floors with tarps and were very careful to protect my walls as they moved equipment in and out. Josh, the son of the original Jim, was on the job working with the other two installers. They performed above my expectations. They left my home and yard as clean as if they had never been there. The new furnace is wonderful and is already saving me money on my P.G. & E. bill. I would recommend Jim's Air Systems unconditionally to anyone in need of a new furnace and AC system. This is a family business that has been supplying and installing systems since 1976. They take personal pride in doing an excellent job. They did not sell me anything that I did not need and provided me with a much cleaner and easier-to-service installation than my existing system. They are the best! "

"My AC stopped working last November, and since then i had 4 contractors i called to fix it, i was turned down by everyone. i called Tyndall and peter came out and talked about it with me, actually troubleshot it, and 2 days later had parts and fixed it. i would give them 6 stars if i could. im so glad to have my ac running again. my recommendation, if you want something done, call Tyndall, because the rest of the contractors seem to just say its not fixable and leave without even looking at it. these guys were the first people that listened, then looked at the unit before declining service, and then actually fixed it. 10/10 great job and thank you."

"The plumbing technicians came out as promised to assess the leak. They were both very courteous and kind and assessed the damage. I am giving three stars because they estimated the cost to be almost 250% higher than what the actual cost was to fix the issue. I am sure there are customers out there that would just accept any bid however, please get multiple beds for these projects, especially when working with this company as they will inflate the cost to take advantage of the situation. I ended up only paying for the $79 estimate."
