My furnace is down in cold weather. I called AIS. Its scheduling and updating is very friendly and prompt. Technician (Olim) is very knowledgeable. After he saw the issue, he immediately say he knows the issue. He fixed it and followed by through checking to make sure no other issues. He explained the procedure clearly. Great job.

Samantha was so very helpful and a joy to work with while scheduling the technician. Pete got to my house exactly on time. He was so very professional and clearly knowledgeable. He did a thorough assessment of my heater, explaining each test and the results and what they meant. My heater is back up and running perfectly. I will continue to use AIS for all my HVAC needs!

We've been using AIS' services for regular HVAC maintenance and repairs over the past few years. Recently, we decided to get our HVAC system replaced as our current one was well past its serviceable life - Ari clearly explained our options for gas furnace vs heat pump taking into consideration our specific situation related to solar power headroom, our preference for a less noisy system and adjustments in airflow in specific rooms. We ended up selecting the heat pump option considering the efficiency, discounts and tax credits. The installation team (Alex, Fausto and Juan) did an excellent job with the install, we can see the professional effort they put into making everything done just right (in our rather narrow cabinet), and also explained the full system to us after the install and answered all my questions. The system has been running very smoothly and silently. Thanks to Genell for scheduling the consultation and install and explaining the process clearly. I'd highly recommend AIS for everything HVAC.

AIS technician came in today and quickly fixed the heater that the gas valve was shut off since last service. We endured 8 days without heater and no more bundle up as Pete thoroughly adjusted the temperature up and down to make sure it works properly. Nice to have someone knowledgeable, interactive to our service.

10/28/24 - I’ve been so impressed with AIS the past couple of years, when I heard they also install water heaters, I asked for an estimate. I was surprised to receive the quote from AIS owner David Sojkic! The personal touch like this affirms my trust in this company. I am confident that their expertise also extends to water heaters too. I’m hoping to push the GO button on this project in the near future. Thank you Mr. Sojkic!

10/25/24 - Just had my fall furnace scheduled checkup by Mr. Sergio 2.0! Burners, PC Boards, filter, etc. were all checked and cleaned. He even shined up my thermostat electrode! A very thorough job. I’m completely satisfied that this annual maintenance contract is a great investment. I highly recommend it. AND it’s a complete pleasure to see Mr. Sergio once again.

4/26/24- This is my scheduled spring AC checkup. Met Sergio 2.0! Friendly, efficient and informative as I have grown to expect from AIS. I’m happy to see that the young AIS staff continues the tradition of quality care!

11/8/23 - I had my scheduled winter furnace checkup. Sergio Sanchez was efficient, knowledgeable and polite. I continue to be impressed with the AIS family!

4/13/23 Update - Today I received my complimentary first year inspection. I was privileged to meet Mauricio, another of the outstanding AIS family! He thoroughly inspected and tested my system and provided added tweaks. Per our discussions, I requested a surge protector which I would have overlooked had he not mentioned it. Our recent windstorm caused a massive power outage, on consequent line surges when power was restored. I also signed up for annual maintenance to ensure my system continued to perform well. I was so impressed with Mauricio’s depth and breadth of knowledge. I will continue to recommend AIS to all my family and friends.

4/2022. My 40+ year old furnace was due for replacement but COVID kept me from wanting folks in my home for the past two years. As infection declined I casually looked around for reputable HVAC installers until I came upon AIS Heating and Air Conditioning through NextDoor. Many neighbors I consider reliable raved about this local family owned company. That was the clincher. I called for an appointment and met Candus a few days later for a quote. I was worried about the timing of the installation but Candus and even the owner, Daniel Sojkic pulled out all the stops to install before my daughter gave birth. AIS FINISHED THE JOB IN ONE DAY! I couldn’t believe it! This was a new furnace AND AC! And the job was done perfectly with the highest craftsmanship and professionalism. Plus the Super Crew: Rafael, Juan and Gil were so friendly and polite. Like family! I would highly recommend AIS, and I already have!

Zack was friendly, knowledgeable and skilled. He fixed the furnace so well that it works much better than it ever has in my 32 years of living in this house. However, the pricing on the repairs is too high. Next time I will be getting 3 free estimates before I go through with a repair.

Leon did an amazing job on my duct inspection. I recommended everyone have their ducts inspected each year, especially if they see signs of critters in the attic or crawlspace.
