My AC was not turning on. I had already tried several troubleshooting steps myself but could not figure out the problem. I saw the great reviews for AIS and noticed a $58 service call special advertised on Yelp, so I reached out. Making an appointment was incredibly easy. Brenham arrived in just a few hours. He was pleasant to work with and clearly knew his stuff. He quickly diagnosed the issue and fixed it; it turned out to be a disconnected wire, so it was a pretty simple fix. While he was there, he also looked at another issue I was having with my heater short-cycling. It turned out the motherboard needed to be replaced, and he luckily had one with him. The price was on the higher side for a relatively simple swap, but I understand I am paying for his expertise, and since he fixed my AC on the spot, it seemed fair. He offered various other upgrades and maintenance plans, but all of that felt unnecessary for a 34-year-old system that is on borrowed time, so I declined. I would definitely use this company again and was very satisfied with the service. read more

My furnace fan/blower would not turn on and with being two days away from mid-to-high 90 degree weather arriving, I was dreading how to live through the heat without air conditioning. I called around and AIS came to the rescue. They were able to send a technician, Brenham, out the same day! My window was between noon and 3pm. I got a text from the office at 12:30 that the technician would arrive close to 2:30. Even though that arrival was within the window they had already communicated, they still thoughtfully reached out to give me a more precise time. This was much appreciated as it allowed me to run out and do a couple of errands before the technician arrived. Brenham texted me about 20 min before his arrival saying he was on the way. He arrived right on time and was very respectful and had a nice, easy going demeanor. He got right to work troubleshooting the furnace, explaining to me how he was approaching the task, which I appreciated. I even learned a couple of things about furnaces! The issue ended up being the furnace's mother board and the "universal" board he had was not compatible. I feared this meant he would have to order one and it would be more days without AC. Brenham said he would check his van to see what he had and thankfully had the exact board for my furnace. He replaced the board and the furnace blower turned on! Even though my issues was resolved, he took the extra time to check on my outdoor AC unit and did some diagnostics including checking the refrigerant levels. It was a nice "extra comfort" to know the AC unit checked out fine. I was in a jam and AIS came through for me. Brenham was extremely knowledgeable and did great work. HIGHLY recommend AIS for all your HVAC needs. read more

AIS installed heat pump systems (2) at my house 2 years ago. very happy with the decision. Since then Leon Rivera has been our regular maintenance/inspection technician and has done a very conscientious/thorough job with each visit. Most recently last month (June). Checked everything out, answered all my questions and left us very confident that the cool air will come when needed during these hot summer months. read more

Pete Bell was an excellent repair man. Was very thorough and happy to answer questions about diagnosing the issues and the repairs needed.

We had a tech named Brenham Purves come to our house due to the A/C not working. He arrived on time and was able to ID the problem quickly and get the correct part on order for us. He arrived the next day and installed a motherboard and all is working well. He was very knowledgeable and was very clean with his work area. We would definitely recommend him and AIS. read more

I had an old furnace and with the weather getting warmer, wanted a heat pump to provide cooling as well. Contacted several companies around the Bay Area to come by and give estimates. AIS and their team provided the most education and took their time to answer all my questions. Their pricing was fair. They didn't try to sell me anything I didn't need, even though I challenged them a couple of times of why didn't they recommend a stronger system. "We live in California, the weather is milder. The premium on it, you'll likely never use." I appreciate their honest business practice and would recommend talking our sales rep, Art. The team that did the work was also great. They worked hard to install the system and keep the aesthetics of the house. Took care of the house more than I do myself if I'm frank. Shout out to Rafa and his team for getting me set up right. I also want to give a shoutout to Leon, who finalized the inspection and gave the final tests and touches to our system. He made sure I was acquainted with the system and was helpful with the usage strategy. Genell and the entire AIS team were great to work with and are a local based company. I highly recommend them for any HVAC service. read more

We had a new HVAC system installed three years ago, not by AIS. But we had multiple issues with the install, so I signed up with AIS for inspections and peace of mind. Jair Ryan (JR) came today, and did an excellent job. The drain pan was already rusted from ice issues, which shouldn't happen on such a new system. He determined that the (other company's) installers had put the refrigerant regulating sensor in the wrong location, and after moving it, metrics improved. He also installed a water sensor to stop the AC if this ever happens again. JR was efficient and explained things clearly. Would highly recommend. read more

I had my annual AC inspection done a couple of weeks ago had would give them a mixed rating. The good: techs were knowledgeable, provided a detailed report on many components, and provided a lot of information on my system. The bad: as part of the check-up, they provide recommendations. One of those recommendations was to replace the current control due to measurements being outside of manufacturer specs. When I took the same measurements on that same device, I got a different measurement that was well within the manufacturers spec. I had replaced this component just a year or two ago so I was surprised to learn it was already showing signs of aging. Needless to say, if I had followed the recommendations, I would have spent several hundred dollars on a part that didn't need replacing, at least according to my own measurements read more

Pete B was very professional and gave recommendations for my outdated furnace. Service was very quick. I'd recommend AIS.

I have had the privilege to work with AIS on several projects in the last year, their technicians Fausto and Able were prompt, efficient, and know their scope of work, they also took the time to cover the work areas with coverings. Having been in the construction business for 50 years I would recommend AIS for any HVAC work you may need done.. read more

We have called on AIS several times and they have been great! They replaced our aging AC compressor with a new one that works much better. They ran new ducting and adjusted settings for a room conversion. We had some confusion with thermostat settings for our dual zones and they helped us figure it out. And we have had them back twice a year for regular maintenance, including our most recent visit from Pete, who checked everything including the attic furnace and blower, adjusted the system for greater efficiency in Stage 2, and changed the filter. Pete was friendly, neat, and respectful of our home. We recommend AIS to everyone who needs help with their heating or AC. read more

Just got my heat pump with AC installed by AIS. Im impressed by the quality of their work. Everything on my system is setup clean and tidy. The new heat pump looks amazing. The AC unit is super efficient. It consumes way under 1kw/hrs. I got to see it work during the winter and it's very efficient as well. I was initially concerned about converting from gas to electricity... now Im happy with what I got. Leo Rivera just rechecked my system today and couldn't be happier with their service and quality of work. read more

Our AC wasn't cooling our home so we called AIs Friday evening and they came first thing Saturday. Pete went above and beyond making sure he explained everything he was checking and ensured our AC got what needed to be done. Not once did he make us feel that he was trying to push any services. He was very honest and overall kind. I wouldn't definitely recommend Pete and AIs read more

Add one more comment to the inspection service by Leon Rivera. He answered my questions, made adjustment to make the room heat up a bit faster. Give 5 star for inspection service.

I had to replace all my ductwork under the house(rat damage). The AIS team was smart, respectful, fast and hard working. My wife and I were very comfortable with Leon, Gustavo and Abel. Their workmanship and teamwork was first class. After the job was complete my registers were all blowing with greater pressure than ever before. This was due to the fact that they resigned the configuration of the ductwork. Therefore maximizing my airflow. Thank you AIS team for a job well done! I will be referring this company to all my colleagues. Aaron Larson read more
