Our new boiler, purchased through another company, kept conking out. Their techs came out and got it working again each time. However, it's been a cold winter, so I called Onofreo to double check and make sure the boiler was actually okay and working right this time. Mark, the owner of Onofreo, came out a checked things out. I'm really happy with his professionalism. He explained everything clearly and didn't try to sell me anything. When my contract is up with my existing company, I'm definitely switching to Onofreo for annual maintenance.

I had an issue with my furnace last year and a local company told us it had a crack. Since the furnace was fairly new, we called Onofreo for a second opinion. They quickly determined there was no crack — just a small faulty part — and fixed it on the spot for a fraction of the cost. We now use them for our annual maintenance, and they’ve been great! Highly recommend

Previously, I was very happy with our service which is why I stayed, until now. I had an issue with my boiler leaking and they never even came out to look at it. They requested that I take and send photos, which I did. Then, they said I needed to replace my boiler and requested more photos for a proposal. I sent the additional photos and was told I would receive a proposal to replace my boiler. I followed up when I didn't hear anything. I still haven't heard anything - 9 days later. After my initial call was because my boiler was actively leaking.
Luckily, I took the advice of others and reached out to another company that came out to look at the issue in less than 24 hours and was able to repair the issue.
