William is very patient and professional. I recommend him highly. His quote was very reasonable for the mini split installation. The installation was very clean and I'm very happy with my Mitsubishi mini splits..have had the chance to test both AC and heat with the crazy weather we're having here in the East Bay. read more

If you're looking for an honest, affordable HVAC solution, look no further. Soto HVAC saved me like $10k and William is a super nice guy who wont steer your wrong. My wife and I have been dying every summer: we work from home and we don't have central air and the room where we work is the hottest in the house. I got quotes from what I thought was an affordable company, sourced through Home Depot, and they wanted $21k to install a 2 zone mini split, or $15k for a single zone. I was shocked- minisplits I saw online were 2k-4k roughly depending on size...How are they adding TWELVE THOUSAND DOLLARS to the bill for something they install in less than 1 day??? I found Soto HVAC through recommendations on Nextdoor and then saw his numerous 5-star reviews. His quote... a very reasonable ~$10k for a 2 zone, but explained to us that based on the size of the room, we likely only needed one zone, and it could help cool the adjoining room. Did you get that? He's wasn't trying to up-sell us on something we didn't need. He wants you to be happy, not broke. You don't usually get that from businesses these days. Long story short- this man is a saint and saved us a ton of money and now I have to put on a sweater in the summer when I'm working. :-D THANK YOU SOTO HVAC!!! read more

Can I give 6 stars!!! We just installed a dedicated mini-split for our master bedroom! Beyond the best pricing by a lot, William was spontaneous in our initial inquiry, punctual both for the estimate and also for the date of install. He made sure to consult me on any aspect that required input including positioning the unit in the room as well as the condenser and adapting to our electrical setup. He kept the work area spotless and was diligent and professional in every aspect of the install! He even looked at our central system and saved us from incurring unnecessary repairs! Thank you William for everything! read more

If you're in the market for a new Mini-Split HVAC system.. look no further. I spoke with probably 5-10 HVAC companies around the Bay Area regarding a mini-split unit for my new 10x10 office shed, but no one came close to William's pricing, responsiveness, transparency and overall customer service. It became clear that these other companies are either trying to charge a premium for their reputation, equipment (think buying a Ferrari when you only need a Honda) or they just have too much overhead with operating costs that it doesn't make sense to do a job with slightly lower margins when they don't have to... I mean, I don't blame them as demand is crazy high right now for these mini-split systems. I literally had 2 companies tell me to go with Soto HVACs quote because they, "couldn't come anywhere near that price". Don't get me wrong, I was looking to do this job right, so I was willing to shell out the big bucks, but finally decided to go with Soto HVAC because of the combination of price + customer service (every consumer's dream). I contacted William in October 2022. He walked me through my options and provided me a proposal/quote for the job. He was so patient with me through multiple delays in the construction of my new office shed. It's worth noting that every time I called William regarding a delay in my project he made me feel at ease and assured me that nothing changed with our prior agreement/quote and to just give him a week's notice so he could add me to his job calendar. He always picked up my calls or was able to respond back that same day... just awesome. I called William on Saturday (1/7) giving him the green light that my shed had been built and my new mini-split was installed that Wednesday (1/11). Okay guys, hang with me here... we've had horrible storms in the Bay Area since the start of 2023.. William comes out in the POURING rain and gets the unit installed in less than half a day. He brought a tarp for the job to ensure my new office didn't get dirty, and when he left it was still in immaculate condition. Before leaving he taught me how to use the unit and provided operating tips to ensure it was running as efficiently as possible regardless of the season. He left the door open to contact him if I experienced any problems or had additional questions. I only leave yelp reviews when I believe companies go above and beyond.. only "five star" worthy companies. I'm no stranger to the fact that it's really difficult to maintain a "five-star" rating in this day/age and in the Bay Area where we all have strong opinions about everything, but I'll tell you right now that choosing Soto HVAC for my Mini-Split had me smiling ear-to-ear from start to finish. You're the man, William. Thank you again!!! read more

I had a great experience with William from Soto HVAC. He was able to get our 2-bedroom home in Alameda up and running with three mini-split units (one in each bedroom and one in the family room). Installation was quick and his pricing was the best I found. I expect he's able to offer such a good price because he's a one-man show. On top of that, William was polite, patient with my questions, and obviously took a lot of pride in his work. read more

William came and fixed my AC unit the morning it went out. He called me back quickly, came within the hour, had it diagnosed and fixed within an hour of that, and was on his way before it really got hot and uncomfortable in the house. William should be your first call if you have any HVAC issues. read more

Such a wonderful and amazing experience working with such a skilled professional. He was extremely knowledgeable and got the work done in three days. Great pricing and flawless work. read more

We went from noticing there was a problem with the thermostat to asking for estimates on Yelp to William being at our door all within an hour, and it was after hours. William replied and showed up quickly and was able to identify and fix the problem. Very professional and friendly. Happy to have found him. Would recommend! read more

***WOULD GIVE WILLIAM SEVENTEEN STARS IF POSSIBLE*** In December, my husband and I moved into an Eichler home in Concord with single pane windows. Sure, we knew it was going to get hot in the summer. However, we were not prepared to have to throw out an ENTIRE PANTRY full of food due to the INSIDE of our home being over 100 degrees for several days at a time. (We had baking flour that was actually steaming. And oh my, you should have seen what had at one time been chocolate chips.) In addition to the NINE powerful fans in our house, my husband and I first tried rigging up window air conditioner ... Nope. A portable air conditioner ... Nada. A swamp cooler ... Worked a BIT better, but only cooled one room down by about 10 degrees. It was time to get real and install a ductless mini-split system, folks. William arrived for the consultation and right off the bat, was one of the most genuinely polite, respectful, friendly humans I had met in quite some time. He listened carefully to my concerns and thoughtfully answered all of my questions. He did a thorough examination of our home and conjured up an inventive system that would provide maximum cooling with (a) less disruption to the original woodwork, and (b) the bare minimum piping that could be viewed from the street (so it'd be more attractive from the outside, and would have greater resale value someday). To note: Eichlers are beautiful, but a lot of contractors hate working on them (believe me, they'll just come out and say it), cause they are difficult to maneuver around. William was up for the challenge. After meeting with William just once, I was sure he was the man for the job. William showed up exactly on time each day - for the three days he installed the mini-split system in our home. He worked efficiently and cleanly. He had the help of his lovely wife for several hours during the first two days. They would leave each room spotless (and I'm a neat freak). We have two dogs, one of whom is anxious. William was sure to warn me before he would enter the home so I could place her in room, and didn't seem the least bit put out if she happed to bark at him through the glass doors. William worked with precision. I would catch him working and I could tell everything he was doing was with intention. He has incredible attention to detail. From start to finish, I couldn't imagine a better experience. It is apparent William takes pride in his work, yet he is not prideful. He is a lovely, hardworking, honest gentleman who does quality work. I highly recommend William Soto of Soto HVAC. read more

If you're looking to have an honest and knowledgable HVAC professional, you will want to call William at Soto HVAC. I'm a returning customer, and I can't say enough wonderful things about him and his company. William has me as a client for life, and I will continue to refer him to all my friends and family. He even made a stop at my new house to help me wire up a blue line for my NEST and insisted that it was a courtesy visit since I'm a returning client. Don't make mistakes and call someone else! read more

Came out same day (day before 4th of July) and had to come back on the 5th for a last part. Was able to finish even without us being home.

At the recommendation of a coworker, I contacted William about adding ductless HVAC to my upstairs bedrooms. But first I wanted to make sure my current HVAC was at least running properly. I had William out to inspect my current whole house unit. Using his testing equipment, we determined that my current 4 ton unit was functioning as designed. We used a bore-scope camera and also verified the evaporator coils were clean. Being cautious, I verified the data with an HVAC friend out of state. He also agreed based on the data that my current system was running properly. However having a 80's split level home with three levels was making it difficult to cool the upstairs. I knew I had decent enough insulation, but the upstairs still was uncomfortable and the AC struggled on warm days. So we began discussing the upstairs system I desired, and came to a consensus. William expertly installed 4 upstairs mini splits and the outdoor compressor unit over a period of about 2.5 days. The new unit sits near my whole house unit outside and runs extremely well. Day 1 was mostly running the lines through the attic and setting the indoor units in place. Days 2 and 3 William spent mostly outdoors running the lines neatly up the side of the house into the attic and connecting everything to the compressor and adding a 220V circuit for the AC to run on. Based on the layout of our bedrooms, some units needed a condensate pump to remove the water generated from the cooling process. If you are installing on an exterior wall, a small gravity line is all you need. But in our case, we opted for the pump because of our specific situation. The condensate pumps are nearly silent and only run occasionally when you have the AC turned on. To close, I can not say enough good things about the work done and how happy we are with the system in general. Its a massive savings to just run one of the units instead of the whole house, and far more comfortable than the whole house could ever make it. read more

My thermostat died. I needed a new one. I pulled my old thermostat off of the wall and saw a bunch of wires. I didn't know where to turn off the low voltage electricity to the thermostat, and I didn't know what wires to attach to the high-tech Nest thermostat. I went to Yelp! and found Soto HVAC nearby. I called their number, William answered, and he agreed to come to my house the next day (a Saturday) to install my new thermostat. WIlliam showed up on time the next day. It took him about 40 minutes to do the installation (he had to go into the attic to turn off the electricity to the thermostat). He then walked me through the setup of the Nest. He was friendly, efficient, helpful and knowledgeable. I will recommend Soto HVAC to anyone without hesitation. read more

William was great to work with on my project. He put in 5 mini-splits in my house and really took the time to do it carefully. He always showed up on time. He worked hard and clean up after himself.

William of Soto Hvac came to my house on short notice to troubleshoot my Mr. Cool mini split.

My 1600 sq ft mobile home needed a cooling system. A mini split unit is the only sensible thing to install. I had 4 contractor proposals. Everyone seemed to be effective, all had a variety of prices for the same equipment and service. I chose William Soto. I read the Yelp reviews, checked the BBB and his company checked all the boxes. He arrived on time, started immediately, working ALONE, he was finished by 3:00. The work was so neat. Everything was so buttoned up. AAAAND, he charged me the least amount. I'm telling all my friends and neighbors. Thank you William, you really rock read more

Two thumbs up and 5++ stars for William Soto!! He installed a ductless mini-split system in my Oakland home two years ago. He was great to work with: showed up when he said he would, explained the process clearly, figured out how to configure the various components in the best ways to meet our needs, got the job done in the time he said he would, and was very respectful and considerate and neat while working. I had received several quotes before choosing William, and I went with him because he is not a big company (being a small biz owner myself, I am partial to the "little" companies), his price was competitive, and, most importantly, he really knows ductless mini-splits. Some of the other quotes I got it was clear this technology was a sideline, not the focus. I am SO HAPPY with our unit. More than I expected. In cools/heats quickly and quietly and so efficiently. We did not have AC before installing the ductless mini-split and our PG&E bill hardly went up at all. Zero issues with the unit, and if anything does ever to wrong, I know I can call William and he will be able to take care of it. I am totally sold on this technology. I have referred at least three other friends and and neighbors to William for ductless mini-split; all have been equally satisfied, both with William and their units. read more

I recently hired Mr. William Soto to install my mini-split ductless system and he was fantastic! When he said he was going to be here at 8:00 am he was here at exactly 8:00 am. Mr. Soto is very neat and clean in his personal appearance. He takes great pride in the finished look of his installation. Everything was mounted level and looks real nice upon completion. When I called around to get prices his was the best by far. He responded promptly when I called and was very nice and polite. Mr. Soto is very easy going and gives you a sense of confidence in his work. I would definitely hire him to do all my future a/c or mini-split ductless work. He finished my installation in 5 to 6 hours and he cleaned up the work site when he was finished and left the area just as clean as when he arrived. He had all the proper tools to get the job done and he leaves you feeling that the job was done right with no short cuts. read more

Soto HVAC installed a Mitsubishi mini split in two rooms and I couldn't be more pleased. Mr Soto was professional and honest, he saved me $$$ by not trying to sell me a system larger and more costly than needed for my home. The work was completed in less than a day and was installed with my needs in mind. He even re-hung a very heavy and large/awkward painting that needed a new spot now that there's A/C for me! Five stars sir! U r an read more

William did a fabulous job with installing our mini-splits and removing all our old ducts, including some old ones with asbestos covering. He was so easy to work with and really worked to install the best system for our house while keeping the quote below the other company we had out to quote us. They said it could only be done with 2 systems, but William found a way to make it work with only 1 and running lines through our crawl space. He only works with ductless, so he really has the expertise in this area. Because of some stucco work we have to complete on our house, he agreed to split the installation. It was great that he was willing to flexible as we have multiple projects going. And as far as the actual product, we absolutely love these things--so quiet, and so efficient! read more

We contracted William to install ductless A/C in the house and could not be happier. William came to look at our house beforehand and was very easy to work with in terms of agreeing where to locate the A/C unit and the outdoor compressor. The bid he provided was very clear, and he was able to schedule our job within the week. On the day we had agreed upon, he showed up on time, took care of the installation, showed us how to operate the unit, and answered our questions. Even my husband, who is notoriously picky about the smallest details, only had good things to say about William's work. Very professional, honest, prompt, and super nice. read more

When can you ever find a contractor with ALL of the following qualities: punctual, polite, cheerful, efficient, well organized, quick, neat, extremely well priced, listens to your questions and requests and organized? Until I met William I would have said 'impossible'. William installed a wonderful ductless mini split system for us this week in the exact time he said it would take. We could not be happier and I am pretty hard to please. He came to do the estimate and did all the work himself. A really delightful change from the hard sell big companies where the salesman does the estimate (way higher then William's) and the person, or people that show up to do the job have no idea what the salesman has promised. This is a no-brainer: if you want a mini split - GET WILLIAM! read more

I am a single parent of four children,but I did not need to tell William how urgent it was for me to get my furnace repaired.

I would definitely recommend him to all & use him for future needs read more

I decided to install a ductless mini-split system in my rental property in Lafayette. I called the top 4 contractors from Yelp and 2 from Craigslist. On the day I had them all scheduled to quote the job, William was the only one to show up on time. William and 1 other were the only ones who could speak intelligently about the system and installation methods. The other company came in at 50% higher than William. William was able to get me on his schedule for the following week. He had the job completed in 2 days despite running into some unforeseen difficulties (didn't try to charge extra for these - another big plus). The tenants were very pleased with his efficiency and professionalism. He laid down plastic to keep the house clean and was very polite and respectful to the tenants. I highly recommend Soto HVAC and will use William anytime I need HVAC services. read more

Had an excellent experience hiring William Soto to come temporarily relocate my A/C unit in the backyard. Was expecting him to disconnect the unit and leave - but proceeded to get a hand truck and move to a temporary spot (the thing is huge) so that I could have new concrete poured.

William answered my email query almost immediately on a quote for installing 2 Mitsubishi energy-efficient a/c-heater ductless units. He came over as promised and after a very quick but thorough walk through, sent me a quote which was itemized & very reasonable.
