Ongaro and Sons installed a tankless water heater for us, and everyone from the Mike in sales, to Tony doing the pre-visit, to Omar and Zach installing the water heater, were professional and nice. Omar and Zach were so careful to keep things clean and organized, and the new water heater opened up so much room in our closet! Really great experience and would recommend.

We had a sump pump under our rental installed by Zach and Felipe. What professionals and fabulous work they did. Absolutely care about everything being precise and fitting perfectly. They have gone above and beyond our expectations. We are not easily impressed but these two gentleman did a superb job. We watched the whole process and were amazed at every little detail they made sure was correct. Would hands down recommend Ongaro and Sons and definitely these two men. Very kind and personable. Thank you Zach and Felipe for a perfect job.

I recently called Ongarro and Sons about a tricky problem involving an intermittently operative stove and a balky breaker box. Their technician, Rene, sorted everything nicely and (bonus!) taught me a lot about how electricity works. [This is not so dumb as it might sound. I always expect techs to be able to explain in language I can understand just what they're up to.] I would call on her again in a second, and indeed I'll be doing that after the holidays for a comprehensive electrical inspection. Excellent job!
Ongaro and Sons: definite keeper.

Buyer beware!! I have no idea how this company has a high rating. I would say my experience with this company is they were dishonest at best and unethical at worst.

To start, we called for an emergency service on our heater that went out on a Thursday and they said they couldn’t get to it until Tuesday (not sure how that is emergency service). When the tech got to our house they tested a few items inside on the thermostat and outside on the unit. Seemed like the kid was new because he was outside on the phone diagnosing the issue. Came back with some pictures which they obviously use as the scare tactic that the tech claimed the unit looked rusty (it was not, it was dirty but clearly not rusty) and cracked (it was not, those are welding lines) which could “be leaking carbon monoxide in my house “ , told me my unit was going to give out soon. He then proceeded to tell me that we should get a new unit instead of prolonging the inevitable by fixing it. Oh by the way, the unit he claimed was about $20k!!! I said what?! That’s insane. He then admitted their mark up is a significant portion of the cost (like duh!). He said someone would call us to provide options on next steps without ever fixing the problem (they never called back probably because they knew I wasn’t dumb enough to go for the $20k replacement).

I called another company and they fixed the issue in about an hour for $350. They also said there was no cracks on the unit and the “rust” was superficial and not a concern. As suspected, Ongaro seemed to want to take advantage of what one might assume an unsuspecting female they obviously thought could be scared into making an outrageous purchase. Everything about this interaction with Ongaro felt manipulative and dishonest. Do better!! If you do the right thing consistently you earn the customer.

First-time customer with Ongaro & Sons and received great service from Joshua V. I needed a second opinion for my older furnace, which had a possible compromised heat exchanger. I needed to know what is the true level of urgency to get the furnace replaced. He was very friendly, very articulate and knowledgeable, and 100% honest with me and told me exactly what I need to do going forward, and helped me to formulate a plan that works perfectly for me. I felt a wave a relief having all the correct information and a good plan of action. I really appreciate the clear explanation. Very reassuring. I am switching over to Ongaro & Sons!
