Bowman then charged $2400.00 for a circuit board and more Freon!!! Only reason I'm having them come out again is we have one more maintenance call due & paid for Which is needed since system totally not working due to a power surge a day ago. BUT! I will then have Onofrio take over and deal with my properties. Shame on Bowman and kudos to Onofrio!

Our house steam boiler in Hamden failed and we needed a new one. Our long time heating contractor…read morehad likely contributed to the boiler cracking by setting it incorrectly so I looked on Yelp and in addition to getting a quote from our current serviceman, asked several others for quotes. Ray quickly responded and not only offered a better price; but seemed to be very knowledgeable about our system. He came to our house and was able to get the old unit working temporarily at no charge and further impressed us with his knowledge. I felt we could trust him and ordered a new boiler from him and also a new gas hot water heater as it was near the end of its life. We put a deposit on the parts and when they arrived he and an assistant installed them. Their assembly work was excellent, he skillfully adjusted the new units and all is now working better than ever. We will use him going forward and highly reccomend him. TR

I also appreciate that he took the time to explain to me how the unit works, telling me about what each part is and does, and about some other noises I might hear that are perfectly normal (very informative and helpful, esp as a new homeowner who is just learning everything about everything home-systems related!)
