Recommended Customer Reviews

They always show up on time and carefully explain everything that they are doing. You never feel like you aren't getting what you paid for.

We were very lucky to get Chris out here to repair our heating unit ducts before winter hit. His work was efficient, thorough, and about half the cost I was expecting. He also managed his way through our very creepy crawl space with no complaints. Thank you, Chris!

They Don't provide a job breakdown of cost of plumbing jobs ! Over price quotes $$$
They do quality work if your rich call them !

Mr Juvencio arrived on time, did the service scheduled, and made a minor repair. He was thorough, efficient, and quite knowledgeable. A pleasant experience.

Ongaro plumbing is way overpriced. All the good sales staff and warehouse workers have been fired. They don't care about their employees, hence, crappy service, but they don't care...

My rep Dustin gave Fabulous service with full explanations and prompt resolution of both my electrical problems.
The office communications were excellent, as were Dustin's en route updates.

Thank you to Chris & Jeremy at Ongaro and Sons for installing a new breaker box at my house. They were polite, professional and hardworking.

We recently hired Ongaro and Sons to do some electrical panel upgrades and install a heat pump for cooling and heating in our home. Everybody there was professional and helpful, especially the installation team of Maxwell and Eric, who were courteous and efficient and got the job done right the first time. The whole HVAC team extended themselves to enable us to meet the deadline for Sonoma Clean Power's rebate and we are super grateful. Highly recommend this company.

Ongaro and Sons recently repaired a leaking drain pipe in our house and very efficiently completed the job and below their estimate.
Then they replaced all our heating/AC ductwork again very efficiently, politely and at their estimated price. Gustavo and Sal were the main installers of the ductwork and we must say that they did a wonderful job. They are very polite, considerate and nice to work with.
It is obvious that Ongaro and Sons is a high quality company that takes good care of their employees. This shows in their attitudes and work ethics.

Nathan was terrific. He took the time to diagnose the big picture in our house, which made it possible for us to take care of both our current electrical problem and address some important safety concerns that other electrical companies did not address. Ongaro's bid was a little higher, but we feel it is well worth it. And besides, we just appreciated the thoughtful, professional, and comprehensive service that Nathan provided.
