HVAC reviews in San Anselmo, California

We've used Ongaro & Sons to install air conditioning, move a thermostat, and recently to consult about outdoor lighting. We've been very pleased with their services and have found all technicians to be competent and extremely pleasant.
My most recent interaction was with Mark (fabulous) who moved the thermostat, and Renee, who saved me money by suggesting they install new outdoor fixtures rather than add more outdoor lighting.

Ongar & Sons has been instrumental in getting our AC unit fixed during when the weather was extremely hot. Great customer service the office was very helpful in getting someone to come out and ocenia the problem. I just signed up for their maintenance service for my HVAC system so that we can prevent any problems and address any issues before they become big issues.

I highly recommend Ongaro and Sons. After speaking with several plumbing companies about replacing a failed section of my home’s sewer system, Ongaro and Sons offered the best pricing and delivered outstanding service. Special thanks to Aldo and Amado for making the entire project seamless!

First of all, Kristopher was amazing! He went above and beyond with his service even when some of his equipment was not cooperating. He was friendly, helpful, and professional and I felt like we were in great hands with him. Would definitely request his services again. Second, I have never had a service company as communicative as Ongaro. They were right on time and gave me a heads up when Kristopher was on the way. They also sent plenty of reminders and I appreciated knowing what the visit would cost before committing to anything. Would highly recommend them to everyone!! Thanks Kristopher :D

After years of seeing their trucks driving around Marin, I finally had my first experience working with Ongaro & Sons and I couldn't be more pleased.

From my initial phone conversation scheduling the appointment, to their service at my home, they were very friendly, courteous, and most of all helpful. They worked with my schedule to find a day and time that worked best for me. The morning of the appointment, I received a text from them letting me know that my serviceman Ricardo was on his way along with a photo so I knew who to expect. When he arrived, he was very professional and continued the same helpfulness I had experience when scheduling. He explained the services he was going to perform beforehand to make sure I understood everything and happily answered all my questions. It was a routine furnace tune-up. He was thorough and efficient with the work and had completed the job very quickly.

Very happy overall with Ongaro & Sons. I cannot give them enough praise. If it were possible, I'd give them six stars on this review. Consider this public praise that 6th star. Highly recommended.

Ongaro came and replaced and rejuvenated all our fuze boxes. From the estimating through the execution the procedures proceeded flawlessly, and with charming help from the main office.
A thoroughly pleasant experience throughout.
Highly recommended.

We were so impressed with the punctual, kind, professional, and cost-effective service of Ongaro & Sons! Douglas was fabulous in trying to help us figure out what the debris in our water was. He spent a lot of time looking over our water heater, piping in the basement, and water quality itself. Definitely going with these good people again!

I've been working with Ongaro and Sons since 2003 on 3 different homes. It's always a great experience. Great crews, super professional, very friendly and they always stand by their work.

Needed a shut off valve installed today. Called Marie who went beyond to get Nico out for the service. Excellent customer service and technical know how to get it done. Will definitely use them again. Well Done!!

Great customer service and fantastic work.
We plan to make them our go-to electrician.

Ongaro did another outstanding job on our kitchen sink plumbing repair. Your plumber, Jeffrey, was outstanding from both a professional and personal point of view. This is why we always come back to Ongaro for our plumbing needs. Thank you. Mike Peters and Rene Hooper-Peters

They arrived on time and worked well as a team replacing my water heater and bringing it up to code. They finished promptly and cleaned up after themselves. I definitely recommend Ongaro and sons to do your plumbing needs

Thank you to Salvador, Dominic, Chris, and the whole Ongaro team that speced out and installed our Mitsubishi ducted split system. They threw a lot of people at it the first day, got all the big pieces in place, and did masterful work on the second / last day. I appreciated how they kept track of everyone in the attic on a hot day, the respect they showed for our home, and how quickly they came up with solutions for little things that cropped up. The install was completed about two weeks after we gave the go ahead for the project. Wow! The unit is much quieter than our old gas fired unit. I was surprised how excited I am about our new heat pump. Everything has gone without a hitch so far, so we don't expect any issues this winter. We are delighted with our choice of equipment and HVAC contractor.

Ongaro & Sons replaced my main electrical panel. They were very professional, did a nice job, cleaned up and charged a very reasonable price. Highly recommended.

My service techs, Nico and Nick, were a pleasure to work with. They are extremely nice people that are very knowledgeable about their trade. Ongaro as a whole is also great about communicating and scheduling appointments.

Ongaro and Sons is a first rate, honest and high quality company.
I have been doing business with them since 2022 both electrical and air conditioning. Their technicians are polite, honest and informative. Their work s a good value for the quality of work performed.

The professionalism and friendly manner of Jayson and Ongaro & Sons made me feel like a valued customer as opposed to a number. I highly recommend Ongaro & Sons as they were on time and ready to service our air conditioner with all the parts on his truck!

I have no idea how this company has so many positive reviews, but my assumption is that no one is calling around for other quotes.

Ongardo & Sons recently came to address some leaking we had below our house in our crawl space. They did have good availability, but that is where my positive feedback ends. From the minute their technician stepped in the door I could feel that he was selling me, but they had such good reviews, I overlooked it. He diagnosed the issue to be a leak from one of our pipes to our sewer main and a leaky water heater. He also shared that a lot of our pipes looked old, which is true. He roughly quoted me $25-30K to repipe everything, which we were prepared to do. He said that we would immediately need to replace our water heater and quoted me $5,000. I didn't think to get another quote for that because I figured he wouldn't over charge me knowing that a much larger job was possible. He also talked about adding in a discount. I put down a $500 deposit and the work was supposed to begin on the water heater the next day. After he left, I looked up the model they were going to install only to realize that I could get it from Home Depot with installation for more than $2,000 less. I immediately cancelled the deposit and the job. Despite me paying with a credit card less than an hour before, they had to mail me a check. I never received the full quote for the larger job. After they sent me the $500 check, I realized they charged me $515. When I called to ask for the full refund, they said the $15 was a third party fee, which was never disclosed or I would have paid by check. After complaining, they finally agreed to refund me the $15.

Ongaro & Sons tries to nickel and dime you from the get go. They care more about making money than anything else. If you are considering working with them I HIGHLY recommend you call around to other plumbing companies. We ended up getting quotes for the larger job from two other companies, both of which were much better to work with. In the end, we have spent over $25,000 with another company, but I'm sure if we had gone with Ongaro it would have been at least 25% more for no better work or service. I will never know because they never even followed up on the initial quote.

Abel was like an Angel in my life today! He is one of those rare workers (and humans) who still values kindness, positive communication and excellence in his work! Thank you, Abel! Ongaro is lucky to have you! Best wishes.

Alex Johnson from Ongaro luckily came today to address my leaking water heater - much earlier than my appointment 4 days from today. I needed a specialist that is well-versed with Hydronics/ Tankless triangle water heater/ boiler system and much to my luck, it is Alex' specialty! He patiently and meticulously explained every single aspect of the system and the issue very clearly which I truly appreciated! Alex really truly. knows his specialty and gave me the peace of mind that my water heating system is in good hands and in good order. Thank you very much, Alex! And thank you to Ongaro & Sons for sending him much earlier than scheduled!

I have used Ongaro a couple times. Always pleased.
All the resources are courteous and understanding that often when you call a plumber it is an unplanned need not a want.

They are always willing to inform and educate with their recommendations.

Skilled, trustworthy, courteous ( considerate that they are working where you are living ) .

Plus Family and Local with Northbay spirit - Their customers are their neighbors. Be good , be fair.

Highly reccomend
