"We installed a Fujitsu mini-split A/C and heat pump because installing duct work was not an option. The entire process from getting a quote to completing the installation couldn't have been any better. Joe went over the full scope of the project including the ramifications if any additional work was needed. I don't think one could find a better HVAC company than Airco!"

"I had an incredible experience. My water heater was leaking and ready to let go. Brian had contacted me. He set up an appointment the next morning. The two gentleman ( plumbers ) came in. Removed the old water heater. Installed the New water heater. And updated the vent piping because it was old and out of code. They did a wonderful job. And I cannot speak highly enough of them , the speedy work and their professionalism. I now have a new plumber for all my plumbing needs. Thank you."

"I originally called the company that did my regular maintenance less than a year ago. They told me they couldn't send someone out for 3 days! This in the middle of a cold snap. When I called Rodenhiser, they were able to send someone the next day. While they were not able to completely fix the problem right away - a part was needed - they were able to restore heat while we waited for the part. They came back in a few days and repaired the boiler zone controller."

Customers say: Super punctual

"As part of a second floor renovation, I needed some new baseboard heaters installed in two bedroom, a pipe connecting them relocated/replaced, and some leaky valves replaced on my boiler. Milltown was one of the only plumbing companies that actually returned my calls, and they were able to come out right away, which was great because it was almost October and was starting to get cold. They did an excellent job with all of the work, and I think the price was reasonable for what they did. They were punctual, clean, and professional. No complaints."

"I consider myself super lucky to have had Mike install our water heater, and then subsequently a gas boiler with indirect water heater. He truly IS a master plumber, that boiler looked like a piece of art at the end of installation, and it works like a charm! In addition he did quite a bit of plumbing by moving around a second water heater, to save us some room in the basement - free of charge! Not only is he an outstanding and extremely hard working plumber (you can judge from the number of reviews!), but also a deeply decent man of exceptional integrity, truly an inspiration to all of us..."

Install Boiler questions, answered by experts

Warmed or cooled air can escape your home through drafty windows and doors. If you notice any gaps, be sure to caulk and seal them. You can also hire a local pro for an energy audit to get a list of energy-saving recommendations. 

Finally, check your insulation. It can settle in over time and become less effective. The Environmental Protection Agency (EPA) estimates that you can save an average of 15% on heating and cooling costs (or 11% of total energy costs) by sealing leaks and making sure attics, crawl spaces, and basements have a nice layer of insulation.

Oil boilers provide reliable heating, efficiency, and long-term cost savings compared to electric options.

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.

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.

A furnace takes in cool air, heats it through the burner and heat exchanger, and sends the air on its way to warm your home. A boiler is a pressurized vessel that produces hot water or steam to heat the home and provide hot water. A boiler may or may not work together with a furnace.
