Our house is very old and had some major plumbing issues. Daniel came up with creative solutions to all our problems and fixed everything in a cost-effective and aesthetic manner. Couldn't be happier with Ongaro & Sons friendly and professional work!

They are expensive but if you need a major job done, I would recommend. They fully replaced our ducts, furnace, and installed a new AC unit. Excellent craftsmanship. Following that, Anthony has continued to be outstanding and gone above and beyond to always answer our calls. We had another property outside of their service area but he helped us figure out what we needed to do and validate another company's proposal & work. This was with no possible ability for them to make money off the time he was spending.

If I could give them NO stars I would. They came to service our tankless hot water heater, and the service didn't work so we had to get a new one. After the fact, we found that they are way overpriced. They claim we purchased a membership and have called us numerous times about renewing even though we told them we sold the house and to cancel our membership. When we tried to explain, the woman in the office was extremely rude!

Our hot water heater went out and Ongaro and Sons was able to respond immediately and resolve the issue the same day. Juan was knowledgeable and thorough with the work he did. Very pleased with the outcome!

A total rip off! We needed a kitchen faucet replaced and this simple job was ridiculously priced. When I made my appointment, they would only tell me the $76 fee for coming out. When the plumber got here, I was blown away by the price of a simple 1-hour install (which was ON TOP of the $76 fee for coming out - they do not waive that fee). Their price was 3x as much as any other plumber. How do I know?
Because I told him to pound sand and I hired someone else, who did a great job for a fraction of the cost. BTW, the plumber who came out was very courteous. And like the other reviewer, I cannot speak to their work - only to their prices. But it'll cost you $76 just to find out that they are soooo overpriced.

After two years of waiting, we finally addressed several home improvements. Ongaro has always been a reliable plumbing go-to business; we were quite happy to make them our go-to again for a series of jobs! They are an amazing triple threat of services and the perfect place to make your go-to as well! Services: Water heater installation, Repair HVAC, Electric car charger installation

Kevin, a 3rd generation plumber, obviously loves what he does and is excellent. He's a craftsman with a great personality. He fixed the problem quickly and efficiently and gave me a reasonable quote for replacing our 26 yo water heater. If all the plumbers at Ongaro are like Kevin, this is one fantastic company.
