It's a pleasure to write this review for my favorite HVAC/boiler technician. His name is Gino B and he is with Ongaro & Sons. Gino is friendly, smart, thorough, professional and truly understands the technical ins and outs of heating systems -- and have a technically challenging hydronic boiler. Gino takes the time to explain the problem simply and clearly. I always understand what needs to be done and what it will cost. Gino is a pleasure to work with, and when he leaves, everything works perfectly. If you're looking for a superior HVAC Pro, Gino is your man. read more

Had an urgent issue with plumbing and sewer line. Niko arrived first thing in the morning - was professional, efficient, and showed deep attention to detail and care about our situation. Resolved all issues quickly - Fantastic work and gentleman. Thank you so much! read more

Ongaro and Sons is amazing! Their follow-up on repairing our AC and getting an OEM motor to replace the burned out motor was great. Much appreciate the communication with them and the work of their service persons. A+++ read more

Received a quote replacing ductwork in crawlspace. Got an additional quote for comparison. Ongaro was very competitive and I selected them. The crew arrived on one day and removed the old ductwork. They then arrived the next day to install new ductwork. Everything cleaned up; installation accomplished; project successful. read more

We had used Ongaro for 30 years Of great service. In 2026 I just wanted my heating system checked and was told I had a crack in the heat exchangeand recommended a new heater for about $14,000.00. My heater not that old-so before spending that much I had the heater checked by two other HVAC companies-they both told me my heater was fine no problems-I will never call Ongaro again Who ever is running this is untrustworthy. Are your employees working for commissions? Horrible read more

Chris called to let us know the exact time he will arrive. He was very friendly and knew what he was doing. Our AC and heating system are working again. Highly recommended Chris and the company. read more

If this was a 10 star scale, they'd get an 11. The experience working with Ongaro was top shelf in every respect. From the initial assessment on Friday for why our old furnace was failing through today's (Monday) installation of the new furnace. We were presented with a range of solutions at different price points and features, and landed on one which met our needs and budget. Even helped out with some attractive financing offers. Today's installation team was punctual, professional, and friendly. Would highly recommend Ongaro. They will exceed your expectations read more

It's been over a year since Ongaro & Sons demanded that my furnace was unsafe and turned off my gas. But .., it has worked beautifully. Moreover ... PG&E came and inspected my furnace. He laughed and told me how many people Ongaro and Sons ripped everyone off. Something about "how the sons took over and they're scumbags". read more

The Ongaro service man was very good at his job. but he should have told me he'd like to switch from metal pipe to plastic pipes. And, He should have written down what work he did so I could give that to the Landlord. He told me he could not fix the sink without disconnecting the dishwasher....I had no choice, the sink was unuseable for almost a year...so now my dishwasher does not work! But the sink is back! with plastic drainpipes. The guy worked his butt off, but He Left me with Less than I had ,before he worked on my sink drain pipes read more

I had Ongaro & Sons complete an electrical panel upgrade. The job did get finished, but the overall experience was painful and produced a less than ideal product. They charged my bank account for the full project amount before the work was completed and the tech onsite did not know the list of corrections communicated. To their credit, they did return and correct the items, but only after significant follow-up, and the premature charge was never addressed. Successful projects require attention to detail and communication and that seemed to lack once the project was sold. read more

Abel came for a plumbing problem He was very good, and fixed it He also looked over some other problems, and helped us identify some issues Much thanks BD read more

A special thanks to Cody - who went above and beyond with his knowledge, patience, and attention to detail. His dedication truly reflects the values you read about of the company and made all the difference in my experience. If you need electrical work done, I recommend this company! read more

Excellent service! I was able to have electrician out quickly, Johnny was on time, fixed everything, and had helpful suggestions. I will use Ongaro & Sons again in a heartbeat. The services fee was very reasonable. I love that they are a local company that hires local folks. Definitely give them a call. read more

Ongaro & Sons came back to my home did some repairs and refunded some money from a over charge situation. I want to thank them for stepping to the plate. read more

This is not the Ongaro we grew up with. Read the one star reviews and you'll see a pattern. Service comes out and decides a system is unsafe and recommends an expensive new system. You know why? Because service is on COMMISSION / INCENTIVE and when you offer service a commission on selling new systems guess what happens. They become sales people. On top of that they now tell you at the end of the service appointment they have recorded the conversation for "artificial intelligence." If you decide to ignore the one star reviews, be sure you get a second opinion when they tell you your hot water heater or your home heating system is unsafe. You'll be glad you did. read more

We had a really positive experience with Ongaro & Sons on a recent home project. It's always a gamble when you have an emergency plumbing situation and need someone but don't know who to choose. We got lucky with our situation when they were the only ones that could get to our house quickly to fix our main water shutoff value problem. All of the other plumbers I called either couldn't get here within a reasonable amount of time or didn't bother to call me back (Peter Levi Plumbing!). Ongaro & Sons was not only prompt but offered to arrive earlier than expected. Juan Donan Barragan was the plumber from O&S that did the work. He put us at ease right away, assuring us that what was broken could be fixed. We really appreciated that after worrying about the issue all weekend. He quickly put together the estimate that seemed quite fair and got to work straight away. Within a short time, Juan had replaced all of the broken components and our water was back on. It was a really good first experience with O&S, 100% due to Juan's professionalism. As a result, we're going to hire O&S to do more plumbing work that we've needed to get done and we're requesting that Juan does the work. Every plumbing situation is different and every plumber that does that work will vary obviously. Our experience with Juan from O&S was very positive and I would feel very comfortable recommending them to friends and family anytime. read more

Jeffery was super helpful and very knowledgeable. He fixed a 3 year issue that the actual company that installed it couldn't fix. Jeffrey found the issue and fixed it. I absolutely recommend Ongaro & Sons Very satisfied read more

I've had nothing but a negative experience Ongaro. We installed a new furnace on 11/5/25 and paid extra to get their support on finalizing the permit. After many calls, to them and their 3rd party group... on 4/22/25 I was forced to hire another hvac company - at an additional cost -- to get required repairs on the installation done. Ongaro has a difficult phone system where it's hard to get the right people on the phone. They totally dropped the ball and screwed up our permit process and put the sale of our house at jeopardy as this was a mandated item. I do not recommend this company. They are expensive and don't complete their work. Would give them 0 stars if that was an option. read more

We have had drain problems with our shower since our remodel in 2006. After having drain cleaned out annually we decided to address our problem and get it fixed. Ongaro inspected our plumbing and took photos of the many problems we had. They gave us a bid which we initially thought was high. However we chose them to do the work. They were always on time, polite and very courteous. We were fortunate to get Zachary and Amato as our plumbers. They are a fantastic team of very hard working men. If you hire Ongaro I hope you get this team. Topnotch excellent clean workers. Joanne T. read more

I have used Ongaro for my HVAC and electrical needs for many years ears. I like giving my business to a family owned/operated company. Recently I had them upgrade my 40 year old duct work and my 40 year old electrical panel. From the pre-install visits to the installs, the Ongaro team members were on time, efficient, communicated along the way and importantly, clean. Admittedly, these jobs were pretty straight forward and not really complicated, but I have confidence that if the jobs were larger and complicated, Ongaro would give the same stellar service. Another thing, the Ongaro back office team are friendly, answer any questions you have about scheduling, payment etc and if they don't know, they find out. I recommend Ongaro & Sons. read more

TL;DR - The Ongaro technician never had any intention of fixing my water heater, or even identifying the problem with it. His ONLY goal was to sell me a brand new water heater. My water heater stopped heating water, so I called Ongaro immediately because I'd heard great things about them. That was the last time I had a positive opinion of Ongaro. First, the technician arrived within the last 10 minutes of the 2-hour window. Why do they do that? Would it be so hard for them to call ahead and say, "Hi, we will be there in about an hour and a half, we appreciate your patience"? When he arrived, he looked at my water heater for about 3 minutes and immediately started telling me how much he would charge me to fix the problem. Didn't test a single thing, didn't unscrew anything on the water heater to look inside, didn't test any of the circuitry - nothing. Just immediately launched into telling me it would cost hundreds of dollars to attempt a repair, which would not be guaranteed to actually fix the water heater, or much more than that to replace it entirely. A day later, I got the quotes--$938 to replace the thermostats and heating elements (note that the parts would cost a total of around $50), or $5,194 to get a whole new water heater. Still no diagnosis of the problem. Obviously, I wanted to get a second opinion before I spent that much money, so I called Henry Mechanical. They came out and told me essentially the same thing--$900 to attempt a fix, or $3800 to replace. I was still skeptical about both of these bids, so I asked a friend to come out and check it out, too. He brought his multimeter (apparently neither Ongaro nor Henry can afford multimeters, or maybe their technicians don't know how to use them) and within 10 minutes he figured out that there was no problem with the thermostats, heating elements, or any other circuitry in the water heater. After another 10 minutes, he had figured out that the only problem was the electrical breaker serving the water heater. He then replaced the breaker for $100 total cost, and my water heater works perfectly. Absolute scum, just out to steal good people's hard-earned money. read more

The knowledge and professionalism of Lake Romelli was outstanding. I wished to be educated on the furnace system potential failure risks, and Lake walked me through this topic with care and clarity. He is well trained and demonstrated his expertise. Great on-site customer service as well. I highly recommend Ongaro and Sons based on staff trust. read more

They fixed a 25 year old gas boiler system (radiant heat) for several thousand dollars; then I was advised it all needed to be ripped out for a new system at an outrageous cost. We replaced our system for about one third of their proposal. Very bad experience. read more

Not good. Got the run around when they had to follow up on an error that was made in replacing my hot water heater. Their AI answering system and sales focus results in the usual issues related to profit over customer service. More importantly, their quotes were the highest of any plumbers I have subsequently used. For a toilet fill valve and flapper replacement, their quote was $458. I ended up paying $260. To replace all of the fixtures in a shower tub combination (owner supplied) $934.72. I ended up paying $325 by a plumber who took his time and helped me pick out the appropriate hardware!! Companies only get away with what we let them get away with. read more

Great service! Friendly staff!! Quickly identified the issue and resolved it within a week. Thanks!

Lake has been to my house before, and once again, he provided exceptional service. Not only did he service the HVAC but he explained everything to me clearly. He also explained the optional upgrades that would make the HVAC more efficient. Additionally, due to concerns about rats under the house, he went above and beyond to check out some of the ducts under the house to make sure the rats had not gotten through. I have used Ongaro for a long time (over 20 years) and will continue to do so. I hope I get Lake again for the next service. read more

Calling Ongaro to go in your attic is like taking your car to a crooked shop. For us they made allegations the AC system was dirty and unsafe and had mold and needed $28K of immediate work when everything was fine according to two subsequent inspections. And they did instead of fixing the drain pan problem. I lost several nights of sleep over this. read more

I have had a faulty, Takagi tankless water heater for far too long. The company technical support was terrible and the company certified technician was clueless. I finally opted to replace it with a Navien NPE-240A2. I called on Ongaro to do that work knowing, from my history with them, that they know what they're doing. The service person, Jeff Graham, was brilliant. The install went smoothly, Jeff took steps to minimize any noise and vibrations from the water heater motor, and checked all our faucets to make sure the recirculation system worked as designed. A day later, and now, finally, it takes only a few seconds for hot water to flow from all our faucets. Thank you Jeff and thank you Ongaro. read more

We had a problem with a clogged kitchen drain. Over 30 years of using a disposal resulted in a very clogged pipe. Ongaro came out, assessed the problem and advised a solution. The only disappoint was that the special offer of $88 wasn't going to work on my drain, and I had to wait. After a couple of scheduling mishaps, the problem was finally fixed. I was very impressed with Kurt Johnson, their plumbing specialist. If you ever use Ongaro for a clogged drain or for an older plumbing problem, he is the man. I highly recommend him. read more

Problem resolved efficiently and courteously. We are very pleased with the service we received. Ours was a minor problem: the doorbell didn't work. Well, it does now! Technician by the name of Cody was a model of service efficiency and know-how. What more can you ask for??? read more

Heating/Cooling Maintenance Program - We started the maintenance program with them recently. Servicing the AC and furnace is no fun during peak season when issues could have been avoided with annual maintenance check ups. Brandon was our tech today and he did above and beyond what was expected. He came prepared having read the notes from a previous technician. He evaluated our entire HVAC and whole house fan system and reporting on conditions that were preventing the system from working at peak efficiency. He provided photos and videos of his findings along the way so that I could make decisions on the spot whether to proceed or postpone future work. I don't understand all of the technical aspects but he did a great job of explaining (by showing readings on his testing equip) how our system could be optimized. When it came to preparing an estimate on future work, he was able to pull up costs in real time and summarize the work and gave options for keeping the work reasonable. This isn't our first experience with Ongaro over the years. Probably our third tech and each were equally proficient and qualified. Notification reminders and appt time updates were texted prior to the appt. I highly recommend them for HVAC service. read more

I'm super satisfied with everything from A to Z. From day one, when I called to schedule an appointment, the person on the phone was very kind and sweet. Then I got to meet the plumber, Abel, who was so respectful and knowledgeable. As we all know, dealing with plumbing can get very dirty, but Abel was so cautious about not leaving any mess behind. He had covers on the ground, and he even sprayed and cleaned up after the job was done. I highly recommend this company, especially the plumber, Abel. read more

Two plumbers gave up. One wouldn't even try. Enter Logan from Ongaro who had the experience and the right equipment and had the drain clog resolved in less than an hour. Based on this experience, we are giving Ongaro our business to implement a long-term fix. read more

Our 22 year old furnace needed to be replaced. We spoke to three different companies and Jason from Ongaro spent a lot of time with us to look over our house. He asked us a lot of questions about what was important to us, and came up with a proposal that fit our needs and budget. Afterwards he was always available to answer our questions that popped up. The installation was scheduled quickly and the project was completed in a timely manner with a minimum of fuss. Very happy with our new system! read more

I highly recommend Ongaro & Sons for craftsmen of the highest quality in electrical rewiring and upgrading of main and sub panels, installing HVAC with electric heat pump, and installing solar panels with backup batteries. Ongaro & Sons was General Contractor for these three major upgrades of my home, and I am very pleased. What could have been a difficult three months of household disruption, turned into an opportunity to meet, watch and interact with highly skilled electricians like Ted and Dan and their crew as they exchanged old wiring for new and upgraded the main electrical panel and its sub in preparation for my move from gas to electricity; and with the HVAC crew of Bama, Maxwell and Aaron, who in short time had the pieces in place to bring heat back to my house; and finally the Solar teams of John and Omar on roof and Jeremy and Damien on back-up batteries. Individually they were all competent, courteous, conscientious and cheerful! As a coordinated team--Amazing! Bravo to all! I will appreciate your fine workmanship for years to come. The office schedulers Gannett, Alexis and Emily fielded my questions and concerns with grace and patience, and texted me ahead of each crew's visit. Brava to you and others I may have missed. I appreciated your constant support. read more

We've had two great experiences with Ongaro. Most recently, Chris was on time, well-prepared and ready for our A/C annual inspection. He was respectful of property (wearing shoe protectors in the house), very clear in his communication (see photo attached). He did not try to up-sell us, provided photos of his work, and answered our questions. read more

Lights flicking here and there, tv going off randomly, hmm...time to call an electrician. Ongaro & Sons came out right away and found that the main panel box on the PG&E metered side smelled of electrical burns. They got ahold of PG&E to come open their panel, and, yep, burns from arcing. This would have caught our house on fire. Wow, feeling lucky and grateful the technicians figured it out so quickly. Ongaro & Son promptly got replacement parts and handled getting the emergency permit from the county. After the inspector OK'd our electrican's install, PG&E refused to connect the power because of an address issue/problem PG&E had with the County of Sonoma regarding our property address. Ongaro & Sons Electrical Ops. Manager, Aubrey Selfridge, worked especially hard to get PG&E to speed up the process and get us back on line. He kept us informed on a daily basis and we never felt forgotten. Took a week for PG&E to get their act together but Ongaro & Sons technicians and office helped to keep us comfortable and informed. The attention to detail, the personal phone calls, the "stay until things get done" attitude of the technicians, the kindness and professionalism of everyone at Ongaro & Sons was absolutely amazing! I honestly felt like, and I did have, 5 star service! This company is topnotch all-around. We asked for some of their business card to hand out to our loved ones. Ongaro & Sons will be our "go-to" always. read more
