"I recently asked Nick to remove an old cast iron boiler from my basement, and I couldn’t be more impressed with his service. From start to finish, he was professional, efficient, and extremely knowledgeable. The job wasn’t easy, cast iron boilers are bulky and difficult to maneuver—but they handled everything with great care and precision. They showed up on time, worked diligently, and made sure to keep the area clean throughout the process. The crew also took the time to explain what they were doing and answered all my questions clearly. What really stood out was their attention to detail and respect for my home. They protected my floors, cleaned up thoroughly afterward, and ensured everything was in great shape before leaving. I highly recommend Nicholas Gouveia Plumbing and Heating to anyone looking for reliable, skilled plumbing services. I’ll definitely be using them again for any future work!"

"Jordan did a great job installing a hot water heater in my condo. I was able to him photos of the existing setup and the worn out boiler. So that helped to speed up the process. The following day Jordan was back with a helper and they were finished in a little over two hours. And the best thing....Jordan pricing was very fair."

"Everyone I spoke to at Cotti-Johnson from the estimate through to installation of my generator were polite, professional and a pleasure to deal with. At the outset, the scope of the project and its cost was explained to me in simple and understandable language. The installation took place precisely on schedule and was completed within 3 hours. I received the necessary follow-up calls from the office to ensure the work was done to my satisfaction. I couldn't be happier with Cotti-Johnson."

"Robert installed my water heater over the summer. Then I had a pipe come off my boiler (not related to his previous install). He came right out next morning and took care of the issue. Reasonably priced and even called that night and a few days later just to check to make sure everything was OK. Highly recommend"

Install Boiler FAQs, answered by experts

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.

Radiators are a popular home heating choice in older homes, but they are becoming less common in new-construction homes. According to a 2022 report by Elements Visual Capitalist, only around 1.3% of new single-family homes have radiators and similar heating systems, such as baseboard heating.

While they may not be as popular as they once were, radiators today come with more energy-efficient features that can make them practical for modern homeowners.

Depending on the size of your home and system, as well as any upgrades or add-ons you choose, it may take between three and five days to completely replace an existing HVAC system from start to finish. Your contractor should be able to give you an estimate before they begin the actual replacement.

Probably not. Moving a boiler to a new location is a very different prospect from replacing it in the same spot, and significantly more expensive. Plus, boilers are typically carefully positioned in proximity to pipes and radiators when installed. Homeowners may want to move boilers to free up space, prevent freezing problems that have happened in winter, or solve a noise issue—but it’s a much more costly proposition.

The most important sign of a boiler problem is something happening unexpectedly, which is why regular boiler maintenance is important. Unexpected problems can include strange smells, new leaks, and unexpected noises that your boiler wasn’t making before. Additionally, if a boiler keeps shutting off or can’t maintain a specific temperature range, it’s time to call in an expert.
