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.
