If I could give Otter HVAC 10 stars, I seriously would. For over two long years, I've been dealing with a persistent HVAC issue that was driving me crazy. I've had multiple different companies come out, look at the system, scratch their heads, charge me for "fixes" that didn't work, and ultimately leave me frustrated and out of pocket. Then came Otter HVAC. Unlike the others, they didn't just do a quick, surface-level check. They actually took the time to troubleshoot, investigate, and finally figure out exactly what had been causing the problem all this time. What multiple other technicians couldn't figure out in years, they diagnosed and fixed efficiently. They are hands down the best and most honest HVAC company I've ever worked with. They were completely transparent about the real issue, didn't try to upsell me on a bunch of unnecessary parts, and charged a completely fair price. On top of that, they were punctual, respectful of my home, and just great communicators. It is incredibly hard to find an honest, highly skilled trade company these days. Otter HVAC has earned a customer for life. Do yourself a massive favor and just call them first read more

It was close to 100 degrees yesterday (Saturday) in our area and suddenly our AC compressor unit that which is located outside the house shut down by itself. I quickly went to Yelp to search for HELP, as we were facing 2-3 more days of 90-plus degree weather. I stated my problem on Yelp, and within minutes received 4 replies from local service vendors. However, Otter HVAC was the only company that said they could send a tech later in the day. All the others said they would get back to me on Monday, which would be too late for our busy household. So at exactly 4pm Saturday (the time that Otter promised a tech would come by), the owner of the company, Ali, arrived. He quickly diagnosed our problem, went out to his truck to get the right part, and then had the problem fixed within 45 minutes. While he was here he also suggested some improvements to our system that would increase future cooling efficiency and also provide operational safety. Ali is a true service professional with a nice smile and a winning personality! So I highly recommend Otter HVAC, and will certainly call Ali and his team again first the next time the situation warrants! read more

OTTER HVAC replaced 2 thermostats in our home and did a walk through of our HVAC system to check on any deficiencies and comments on the HVAC system performance. The technician explained the difference in performace of the 2 models/makes of thermostats. He picked up the model of thermostats that we selected (Google Nest) and installed them after lunch. He walked me through the programming and set up the thermostats to the specification that we desired. The thermostats have been working well, controlling the furnace and AC exactly addressing appropriately the temperature changes inside the house. We went on a week vacation and did not have to adjust the thermostats while we were gone. NICE. During the final walk through the technician found the insulation on the piping from the house to the AC compressor was worn and told us we should consider replacing it. We notified OTTER about this item, and they promptly scheduled an appointment in a few days. Tony, the technician came back to put new insulation and a layer of outdoor weather protection over the short pipe. The job was excellent. We will definitely use OTTER HVAC again. read more

Man, I was seriously at my wit's end with my old HVAC system. It was ancient, the vents were falling apart. Then I found Ali. He got back to me right away and came the next day. They were super knowledgeable about the Mitsubishi mini-split, and their price was fair, so I went with them. Best decision ever. They didn't just throw in a new unit, they completely redid the whole thing. Old unit gone, ductwork ripped out, everything sealed up tight, inside and out. Ali was there every single day, working alongside his crew, who were all awesome. I had a ton of questions, and they answered every single one, no problem. And get this - they cleaned up everything like it was their own place. Then, during a super heavy rainstorm during the installation, my roofer had some issues that caused a leak, and Ali even helped me deal with that. Seriously, he went way above and beyond. I've hired a lot of contractors, and these guys are by far the best. No question. read more

I had AC installed on my roof (by another contractor) 5 years ago and it's been so loud every time it kicks on. I'm on the top floor of 3 floor wood-frame building built 1908. It was so loud the owner of the 1st floor could hear the hum conducting through the building. I posted a request for help on Yelp and got a dozen canned responses, but Ali was the only one who actually read my request and made time for a visit the next day. We settled on these really impressive sound isolation springs that allow the condenser to free-float. Also, he reran a new condenser return line which had a kink in a bend, causing extra strain on the compressor. (Adding to the noise.) The result - it's barely audible now. After stressing about that noise for 5 years, it's so refreshing to have quiet. Professional, responsive, speedy. Also, he liked my cats. :) read more

I recently had a heat pump installed by Otter HVAC, and I couldn't be more pleased with the experience. Ali, the owner, was incredibly professional and honest throughout the entire process. He and his team did a wonderful job installing the heat pump and brand new duct work. What really impressed me was the feedback I received from two separate contractors who were working in my home for unrelated projects. Both commented on the high quality of the installation, which speaks volumes about the craftsmanship and attention to detail that Ali and his team provide. I feel like I received great value for the price, especially given the level of care that went into the installation. If you're looking for reliable HVAC services in the East Bay area, I highly recommend Otter HVAC! read more

I couldn't be happier with Otter HVAC. From start to finish, their communication was outstanding. They kept me informed throughout the entire process, showed up when they said they would, and were always quick to answer any questions. Their pricing was fair and transparent with no surprises, and the quality of the installation exceeded my expectations. The crew was professional, knowledgeable, and took pride in their work, leaving everything clean and looking great when they were finished. If you're looking for an HVAC company that delivers excellent customer service, honest pricing, and top-notch workmanship, I highly recommend Otter HVAC. It was an all-around great experience, and I wouldn't hesitate to use them again. read more

Updated Review: Ali and his partner personally came by with a cake and offered a sincere apology for what had happened. I truly appreciated the gesture and the respect they showed. Both of them were extremely professional and polite throughout the visit. They completed the necessary repairs and initially refused to accept any payment, but I insisted on compensating them for their time and effort. Ali took the time to explain what went wrong and made every effort to make things right. Their commitment to customer service really stood out, and I'm grateful for how they handled the situation. I'll definitely be using their services again in the future--no doubt about it. Thank you!! read more

We called Otter HVAC to service our AC unit and we are quite pleased with the service we received from Ali and his team. Finding time on our end for an appointment window was difficult, so I appreciated them actively working with me to find a time that would work. Communication continued via text which was convenient, and they always let us know when they were on their way. They quickly diagnosed the main issue -- a bad capacitor which they replaced -- but they also did a spectacular job cleaning out the AC unit which was filled with bugs and weeds from our backyard. Suffice to say, we are very pleased and definitely recommend Otter HVAC to others in need! read more

The Otter HVAC team went above and beyond to make sure we had the right size systems in place for our needs without overselling us on bigger units. The price was incredibly reasonable and all-inclusive so there were no surprises (e.g., inspections, unexpected duct work and relocation of equipment, etc.). When they ran into a few bumps in the installation, they stayed late to get the job done and were really respectful of our time and space. I just had our vents cleaned after the work by a separate company and they commented on how great of a job the team did in installing the new equipment. I highly highly recommend them! read more

I had such a great experience with Otter HVAC! My AC units weren't working, so I contacted them on Sunday afternoon. Ali, the technician, was super responsive and showed up the very next day. He was awesome--took the time to explain what was going on and was completely honest. No pressure or upselling, just straightforward help. You can tell he's very knowledgeable, and he made the whole process easy and stress-free. Everything's working perfectly now, and I'll definitely call Otter HVAC again if I ever have any other HVAC issues. read more

Highly recommend Otter HVAC! I have two furnace units at my house, and both needed the blower motors replaced. I got a few quotes from other HVAC companies, and Otter HVAC came in with the best price. Ali showed up right on time, was friendly, professional, and had both units fixed quickly. He explained everything clearly and made the whole process easy. I like supporting local small businesses when they do great work, and Otter HVAC definitely earned it. If you need HVAC work done, give them a call--you won't be disappointed. read more

Quick and hassle-free experience from start to finish. Derick came out for the initial quote and evaluation, and it was an easy decision to move forward given the pricing and services offered. Vlad and Tony handled the installation, replacing an old, outdated system, and were both professional and efficient. They were especially mindful of the quirks that come with an older home currently being restored, and made sure everything was thoroughly checked before wrapping up. Will be using Otter for future electric and HVAC needs. read more

His customer service was outstanding--he took the time to explain everything clearly and made the whole process smooth and stress-free. By the end of the service, it felt like I had made a new friend. On top of that, his pricing was very affordable, making the entire experience even better. I would highly recommend Ali to anyone in need of HVAC services! read more

Reached out to Otter to install new smart thermostats in my house after a couple bad experiences with others. Twice I had people come out, charge a service fee, and not complete the work, telling me I didn't have the right wiring. Not so with Otter, they came out and quickly set up one thermostat, and then came back to install the rest. The price was right too, and less than quotes I got from others. Great communication the whole time as well. I'd definitely use them again. read more

We had Otter HVAC and owner Ali install a new AC system onto our existing gas furnace, and the experience was fantastic. Ali is friendly, patient, detail-oriented, and really cares about doing things the right way. He took the time to explain everything clearly and made sure the installation was clean and professional. We really appreciated his trustworthiness and attention to detail. Highly recommend Otter HVAC if you want quality work and peace of mind! read more

I am extremely satisfied with the Otter technicians who replaced my gas furnace. They were not only professional and knowledgeable but also courteous throughout the entire process. Despite the challenging tight place and dealing with an old installation, they handled the job skillfully and with great communication all along. On top of that, their rates are competitive. I highly recommend Otter for any HVAC work - top-notch team all around! read more

I needed a new ac/heating system in my house. Got estimates from a few places and Otter sounded like me knew what they were doing and had a manageable cost at the same time. They sent Jason and Ali to do the work. Both were very knowledgeable and easy to deal with. Answered a ton of questions we had, job was done early and they left the place spotless. Felt like I should write this review in case others were to use them. read more
