Just a quick shout out to say Daniel Chan is amazing. Professional, thoughtful, respectful and such a pleasure to have in your home. Thank you Ongaro and Sons!

Chris Ostrom Juvencio came to my home and fixed a heating problem we have had for the last month. He was friendly, capable, and fixed the heater
in a very short timeframe, as we were expecting guests to be staying with us.
It is nice to know that true craftsmen like Chris are still around.

My tenants were without heat and hot water for 3 days when I tried to find a plumbing service.
Jeff, Zack, and Nick repiped the gas lines (due to gas leaks) in record time. Then made sure PGE came and turned everything back on.
They are hardworking and trustworthy to get the job done!
thank you.

I have been using Ongaro and Sons for several years and have always been very happy with their service. Early this winter my thermostat stopped working and my house was very cold. I called and they were able to send Chris Ostrom Juvencio the next afternoon. I highly recommend Chris. He was efficient, pleasant, and explained what had gone wrong and the best way to fix it. He installed a new thermostat, checked and replaced last year's filter, and was friendly and patient with my Jack Russell Terrier who really wanted to help with everything. Chris was wonderful and I hope he is available to help out the next time something needs to be fixed in my home. Thanks, as always, to Ongaro and Sons for being an excellent company and providing excellent service by excellent staff.

So Ongaro did come through and got their new heater working just fine.
And as I said they did place me as a priority...
Why do I have to call up and whine about a brand new heater though?
Being a retired contractor, I KNOW stuff happens. But dang there is this new device called a telephone...

Dustin was here promptly at the stated time, changed the dimmer switch back so that it covered the drywall, and tole me my refund check was on the way ($75). I am so happy with the service.

Joel the ongaro technician provided excellent service in helping maintain our furnace. He explained throughly the services he was going to provide. We have used Ongaro & Sons for years and I would highly recommend their services. I feel the services were of high quality at a reasonable cost.
