HVAC reviews in Fremont, California

We hired AIS to replace our outdated asbestos-wrapped ducts with a new return system that improved airflow and reduced noise levels.

Art, the consultant we met with, was excellent - he was friendly, knowledgeable, and explained the heating and cooling strategy for our home in a way that made sense. We felt no pressure, but his expertise put us at ease, so we decided to go with AIS.

The installation process was efficient and smooth, thanks to the punctual and professional team. They were also very communicative, explaining everything they did to ensure we understood what was happening. The prices were reasonable, which was a bonus.

We're thrilled with the results - every room in our house now gets plenty of air, and the system is barely noticeable. If you need HVAC work in Contra Costa County, AIS is a great choice. Thank you again to Art, Fausto, Edgar, Jasper, and Abel for doing an outstanding job!

I needed some long-overdue maintenance on my mini split system, and I found Zach to be spot on. From start to finish, the experience was top-notch. Zach explained the job and cost clearly, showing respect for everyone's time. His professionalism made a huge difference - I won't hesitate to use them again for all my heating and cooling needs.

AIS installed our new heat pump promptly and professionally, completing the work in just one day. The team, led by Daniel, Leon, and Samantha, were friendly and knowledgeable throughout the process. They also left the site tidy, making the experience very positive.

Leon did a good job. He inspected both heating and cooling systems and made necessary changes. His report was clear about what he found and suggested for improvement.

Had a good experience getting my furnace fixed by Kevin. AIS did a good job with fast scheduling and friendly staff.

Had excellent annual HVAC maintenance done by Kevin, who was highly professional, friendly, and did a fantastic job overall.

I'd had my 24-year-old AC system showing its age, needing yearly maintenance and frequent refrigerant refills due to high power usage. The rising temperatures brought on by climate change meant I'd be using the AC more often than ever before. Despite this, my gas furnaces were still functioning well.

I reached out to over seven HVAC companies with 4.5-star ratings or higher on Yelp, and five of them got back to me for a free estimate. The process took two weeks, during which I had representatives visit me multiple times to discuss their recommendations. Initially, I was looking into replacing just the AC system, but most companies wouldn't consider it due to compatibility issues with my older furnace.

However, I decided to go ahead and replace both systems – one for the first floor and one for the second floor. The next step was exploring options like heat pumps and multiple speed systems, as their incremental prices were never clearly stated. This meant I had to ask all five initial quote providers for additional quotes and recommendations.

Only two companies seemed willing to continue the conversation and provide more detailed price quotes. Toby from AIS stood out due to his patience and willingness to explain every aspect of his proposal. If he didn't know an answer, he'd get it from his team at AIS. I chose AIS because of Toby's honesty and integrity.

Before signing the contract, Toby modified the terms to include some technical language that I felt was missing. The AIS contract was by far the most comprehensive and complete of all the proposals I evaluated, making me feel very comfortable with the situation.

I opted for a mid-level Bryant system with high efficiency ratings and received one of the lowest quotes among my options. After signing the contract and paying the deposit, work began just a few weeks later.

Garrett and Dylan were my primary technicians on the job in early July. They initially scheduled two days but hoped to complete it all in one day. Throughout the day, additional technicians stopped by to deliver parts or assist with various phases of the job. Toby even dropped off equipment and checked in on progress.

As a DIY enthusiast who does many tasks myself, I have high standards for workmanship and professionalism. The guys from AIS exceeded my expectations. Their attention to detail is evident in the photos. Even after completing the installation, they did a thorough cleanup of all work areas.

Two weeks after the job was finished, AIS scheduled a quality inspection walk-through with Javier, who met with Garrett to review the entire installation. They made some minor adjustments to ensure maximum sealing of the old flue piping.

Since then, I've been exercising the AC system daily and everything is working great. The new system is about 1/3 more energy efficient than my old one, and I'm extremely happy with the overall process and finished product. Over the past two years, I've worked on numerous home improvement projects, but dealing with a specialty contractor like AIS has been top-notch. I highly recommend this company to anyone looking for reliable service.

We needed emergency AC repair during a brutal heatwave this week. AIS was convenient to set up an appointment and showed up faster than any of the other HVAC companies we contacted. When Kevin arrived on time, it was clear he knew his stuff. He made us feel at ease as he tackled the problem. He worked thoroughly and explained what was wrong with our AC, how he'd fix it, and provided tips for managing future issues, including safety valve detection. Our main line to drain condensation water was clogged, causing water to back up into the pan. The secondary line couldn't keep up, but fortunately we caught it in time before any damage occurred - specifically in our attic and ceilings. Having that safety valve detection will definitely be beneficial moving forward. We're grateful for Kevin's expertise and appreciate the convenience of their semi-annual checkups - a great value considering the price we paid.

The technician was extremely knowledgeable, walked us through the proposed work, weighed the pros and cons of each option, and provided clear pricing. The entire process was very professional.

We've relied on AIS for routine HVAC upkeep and repairs over several years. After our current unit reached its lifespan, we opted to replace it with a new system - Ari presented us with choices between gas furnaces and heat pumps, taking into account our solar power capacity, noise preferences, and specific room airflow requirements. We selected the heat pump option due to its efficiency, discounts, and tax incentives. The installation team (Alex, Fausto, and Juan) did an outstanding job, ensuring a precise fit within our compact space and providing clear explanations of the entire system afterwards. They addressed all my concerns and answered my questions thoroughly. The new system has been running smoothly and quietly, meeting our expectations. Thanks to Genell for coordinating the consultation and installation process. I highly recommend AIS for any HVAC needs.

This company is very knowledgeable about their work. They provide solid advice on what to do and how to keep HVAC systems in good shape. Regular maintenance is key, just like a car - it keeps things running smoothly. A big thanks for the expertise from Art Miner, who was professional and looked after us properly.

Kevin did a great job. He walked me through what he'd do before starting, followed up on details afterwards, and presented himself as professional and courteous.

Fausto and Abel performed a great installation of our heat pump and air conditioning system, handling the heavy equipment on their own. Two of them managed up and downstairs as well as the attic, which was impressive. They're also very friendly and easy to work with. It's good they speak English, or we wouldn't be able to communicate with them about installing the controller and other details. Overall, great service from a reliable team.

I've had mixed experiences with AIS over the past year or so. On the one hand, they really delivered on their promises during my last spring AC tuneup in March. The technician, Zack Taylor, was top-notch - explained everything he was doing, showed me all his test results, and left no stone unturned when it came to maintaining my system. I have full trust in this company now.

In October, I reached out to AIS about installing a water heater, and the owner, David Sojkic, personally handled the quote. This level of personal attention is refreshing and makes me feel like they truly care about their customers' needs. I'm confident that their expertise extends beyond just HVAC systems.

My fall furnace checkup with Mr. Sergio 2.0 was a great experience - he thoroughly inspected and cleaned all the necessary components, even taking the time to shine up my thermostat electrode. The annual maintenance contract is a no-brainer in my opinion; it's a solid investment that ensures my system runs smoothly year-round.

Every spring, I schedule an AC checkup with Sergio 2.0, and he always delivers on his promise of being friendly, efficient, and informative. It's heartening to see the young staff at AIS carrying on the company's tradition of quality care.

Sergio Sanchez was my go-to guy for winter furnace maintenance, and I'm consistently impressed by his professionalism and knowledge. Mauricio, another technician I've met, is equally impressive - he provided a thorough inspection and added tweaks that I wouldn't have thought of myself. The surge protector he recommended has been a game-changer since our recent windstorm caused power surges.

I'd been putting off replacing my 40-year-old furnace due to COVID, but when the time finally came, AIS stepped up. Candus provided an excellent quote, and Daniel Sojkic made sure the installation was done on schedule, even going above and beyond to get it done before my daughter gave birth. The team of Rafael, Juan, and Gil were friendly, polite, and like family - I couldn't be more impressed with their professionalism and craftsmanship.

Kevin was very responsive and did an outstanding job servicing my heat pump unit. He demonstrated expertise in explaining UV filtration options, sharing both their benefits and costs in a clear and non-pushy manner that made me feel at ease - it felt like having a conversation with a knowledgeable friend rather than being sold to.

I'm thoroughly satisfied with Pete's service from AIS Heating and Air. The guy arrived promptly, diagnosed the faulty heater, and fixed it on the spot. His explanation of the issue was clear and concise. I've also started a maintenance plan, which seems like a great value given the price. Overall, the experience has been top-notch.

Our experience with AIS was top-notch. We recently had a heat pump and air conditioner installed and received an accurate bid without any extras. The entire team, from installers to inspectors, were professional and courteous. They maintained a clean workspace, protected our home by wearing booties inside, and were responsive to my inquiries via phone or email. I asked several questions before the installation and was pleased to receive prompt answers.

Expert technician with great customer service provided quality assurance on the recently installed system.

Our old furnace hadn't seen maintenance in ages. Kevin dropped by, took a look around, and pointed out problems with photos to help explain them. He gave us some options for fixing or replacing parts without being pushy, and his friendly demeanor put us at ease throughout the whole process.

Leon Rivera from AIS Heating & Cooling conducted the semi-annual maintenance on my air conditioning unit today. He broke down each test result, explained the filter condition and recommended replacement when necessary. The level of detail was impressive, reflecting years of experience with the company, starting with new installations to annual services. This consistent professionalism has fostered trust in AIS, which they've consistently upheld. I wholeheartedly endorse AIS for heating and cooling installations, including water heaters - I recently installed mine with them too. Their thorough work gives me peace of mind, allowing me to rely on their expertise to keep my AC and heating functioning without hassle.

Rafael and Edgar from AIS Technicians installed my central heating and aircon system flawlessly. They broke down the technical aspects in a clear and concise manner. Prior to the installation, I was also briefed by Art on the initial process and suitable options during the quote. Overall, I'm extremely satisfied with their professional service.
