If you are in need of a new boiler or any plumbing work, consider Donovan Plumbing & Heating. Highly recommend!!
My boiler had to be replaced & I was not looking forward to the process of figuring out the best boiler & person / company to install it. It was the biggest home improvement job that I’ve had done for my house. Some companies ignored my calls and / or didn’t get back to me. Not the case with Donovan Plumbing & Heating. From the very beginning it was obvious that John Donovan was very knowledgeable, experienced, & very easy to work, plus he came highly recommended so I decided to

Had John come out and take a look at a leaking propane hot water heater. Based off the setup of my current system it made more sense to go electric. He had the replacement hot water heater at my house the next morning and was able to install everything quickly and efficiently. He even got an electrician for me to take care of the wiring. I will be going back to him for sure.

Our water heater starting giving trouble. A small leak, then a week or so later it became major. I was trying to find a water heater and have it replaced in a hurry. Luckily I finally found John, he realized our desperate situation and wanted to help. He rearranged some things and made this job a priority. He listened to what I wanted for a heater but after thinking about all options I decided on a different system. He gave me the best advice! He basically saved me from a big mistake! John quickly got my heater replaced and actually came out to do a temporary fix so I could turn the house water
