HVAC reviews in Fremont, California

Having an old furnace cause issues is no way to spend winter. Abe came to help sort out the problem, and he did it in a clear and straightforward manner that put us at ease. He explained everything needed to be done without getting too technical, making sure we were all informed. The service was top-notch - professional, friendly, and reassuring. We now have heat and a solid warranty backing it up; with any luck, this will see us through for years to come.

Moe fixed my wall unit quickly and efficiently. He's professional, friendly, and got to the point - identifying the issue and providing a temporary solution while waiting for permanent parts. Highly recommended for reliable service.

Sami and Tim did a fantastic job fixing my thermostat - they figured out the problem fast, walked me through the options, and had it all up and running in no time. Same great service from Moe on the maintenance - thanks again for your work. Highly recommend them.

OMR is top-notch. They showed up promptly, were courteous, and did a great job fixing our heating problem. They also tidied up the wiring in my Nest thermostat and warned me about potential issues with my furnace motor. I'm confident I can rely on them for future work.

We hired Heating and Air Experts to address our A/C issues, which had been unresolved for months. They sent someone named MO who is extremely knowledgeable about heating and air units. He quickly diagnosed and fixed the problem on his first visit. MO is very courteous and patient, making it clear that their service is reliable and trustworthy. If you need help with your HVAC system, ask for MO – he's the expert who can get the job done.

I would strongly advise against using this company. When I informed them that my heater hadn't been used in a while, they initially quoted me $300 to replace my digital thermostat, which they claimed was the problem. However, after it hadn't been used for a while again, they came back and told me I needed a new gas valve replacement for an additional $1,100.

Given that my heater is only under 4 years old, I didn't believe them. I had someone else assess the issue and discovered that pressing a reset button on the side fixed the problem, and I was even provided with instructions on how to do it myself. It then dawned on me that these guys must have pressed the same reset when installing the thermostat - a suspicious practice.

These scammers are preying on vulnerable customers during the cold season, taking advantage of people who aren't aware of their tactics. The heater itself cost $1,100, and I later found out that they were charging over 3 times more for the parts than I needed to replace. I regret falling for it initially, but I'm even more disgusted by their deceitful practices.

Moe, Zahir, and Sammy did an excellent job diagnosing and repairing issues with my furnace and flue. They worked late into the evening and through the night on the roof, getting my heater up and running quickly. Moe's diagnosis was spot on - a previous company had struggled to find the problem. The team's efficiency is greatly appreciated.

We're pleased with the service provided by Heating and Air Conditioning Experts. They arrived on schedule and completed the work with expertise. Their professionalism and knowledge shine through in every aspect of the job. We appreciate the excellent support and service received, and are grateful for their efforts.

Omar and his crew are top-notch. Our furnace quit working when it was freezing outside in late November - Omar showed up the next day to identify the problem as worn-out board/thermostat components, then again later that same day to replace the faulty part, getting us back to warmth ASAP. Quick responses were a huge plus; they saved us from a prolonged stint without heat. The team's professionalism is impressive: they arrived with shoes covered, explained the issues clearly, and fixed everything efficiently.

A heating issue persisted despite my AC running, with no temperature drop. In May 2025, I hired Moe to address the problem and he replaced the starter and booster. When I inquired about potential leakage from my Feon tank via text message, he assured me it was fine. However, just one week later, a similar issue arose. The Freon had leaked out. After multiple phone calls and frustrating discussions, Moe's office eventually agreed to a complimentary fix. My tenants were finally able to enjoy cool air. I hope this fix addresses the underlying problem for an extended period, rather than just a short-term solution.

Had a furnace problem over New Year's Eve, but Heating and Air Experts stepped in on January 1st - the only company that could assist. Abe was great, polite, knowledgeable, and upfront about our furnace being in decent shape despite not being used since we moved in. He covered all his bases: efficient, informative, thorough, and honest.

Impressed they took care of the issue in under 24 hours after I reached out during a chaotic holiday period. Would definitely use them again if I needed quick HVAC help.

Note to the business: would be great if their invoicing system automatically calculated sales tax only for parts from now on - initially there was an error due to incorrect application of taxes to service and labor.

Great service from this company! They replied quickly after we reached out about our heating issue in San Francisco, and they arrived the following day. Friendly and efficient, they fixed everything right away with a knowledgeable technician who was super nice.

Heating And Air Experts were a breeze to deal with from start to finish. They showed up right on time, which was a big plus for me. Their staff was courteous, diligent, and upfront about what needed fixing. The job was done efficiently, and everything has been humming along just fine since then. Overall, the process was seamless and stress-free. I'd definitely go back to them if I need any more heating or cooling work and would recommend them to anyone in a similar situation.

I needed urgent furnace repair after my unit started turning on, so I turned to Thumbtack for help. I found Heating and Air Experts through the platform and was able to schedule an appointment on short notice. The technician arrived quickly and professionally, showing up around 5-10 minutes early as promised.

We went over the issue and I was told that the problem was with the gas valve - Moe had it in stock, so we could arrange for the repair and maintenance for the next day. During the visit, Moe worked efficiently, completing the job in under an hour. He also let me know that the circuit board would need replacement eventually but noted it could wait until it failed completely.

I appreciated Moe's promptness, honesty, and professionalism throughout the process. Given my experience with Heating and Air Experts, I'd recommend them to anyone dealing with similar issues.

I called for A/C maintenance because of a rattling noise. The staff were very friendly and courteous on the phone, and they sent someone over quickly - within an hour. Sami was pleasant and efficient, diagnosed the problem and fixed it promptly. He provided a fair quote and offered to give me a free estimate if there's another issue next time.

My downstairs furnace stopped working last night, but after trying everything online, I realized the gas valve was the issue. I called Heating and Air Experts to schedule a repair, providing them with the model number. They sent over a quote, which was a bit higher than expected for the part cost, but that's how it works.

The technician who came out, Abe, was great. He's gentle, honest, and knows what he's doing. He quickly fixed the gas valve and suggested replacing both the controller board, as they were 27 years old. I opted not to proceed with those repairs, which were more expensive than expected. However, Abe worked efficiently on a Sunday and got my system up and running again.

He also helped me negotiate a better price for the repair of the controller and labor, as well as maintenance services for both furnaces, which he'll need to return to do. It was easy working with this company, and Abe is fantastic. If you have any HVAC needs, I highly recommend asking for him. Thanks to Heating and Air Experts for fixing my furnace on a Sunday – it's much appreciated!

I had a broken furnace that stopped working. A representative from Heating And Air Experts called me on Sunday, which surprised me since they're not usually open on weekends. They sent Sami over right away and he was excellent - very professional, knowledgeable, and thorough in his assessment and repair work. He fixed the problem, did some routine maintenance, and now my furnace is up and running again, thanks to their efficient service.

I'd give a perfect score if allowed. The technician showed exceptional attention to detail and thoroughly explained each step. Their dedication shines through in their work, and communication with the company is top-notch.

Our air conditioner compressor just gave up on a sweltering Friday night, leaving us high and dry. The next morning, I dialed up AIS and they sprang into action, dispatching a technician to our doorstep within hours. Technician Pete Bell showed up promptly and got to work, identifying the problem as a faulty capacitor that he had a replacement part for on hand. It's reassuring to know that the company preps their techs with essentials like this, which is no surprise given how common these issues are in modern compressors. What really impressed me was Pete's attention to detail and professionalism. He walked me through each step of his diagnosis and repair process, ensuring everything was working as it should after the fix. He also took the time to get accurate readings with the system running at full capacity. Overall, my first experience with AIS has left a positive impression – I'm looking forward to giving them another call in the future when we need help with our HVAC.

I had an excellent interaction with AIS HVAC. Leon was extremely diligent during our maintenance visit, capturing crucial details such as system images and underground ductwork through photos. His comprehensive assessment included a detailed performance report and actionable suggestions for upgrades, accompanied by thoughtful explanations that satisfied all my queries.

Zach showed up to service my outdated heating system with a thorough clean and maintenance check. His expertise came with valuable recommendations for upkeep and future care, making the process worthwhile. Appreciative of his professionalism.
