"I posted I needed a window AC unit removed and this company was the only one to respond. The owners wife responded with in an hour, told me they would be at my house 3 days later. I responded, can you give me an estimate of how much it would cost. She responded, sir there is no charge, we just like helping out the community. I was shocked. Being on a fixed income. Craig arrived, removed the AC, and I started asking questions about mini split systems. He was here at least an hour explaining how they worked and my options. I have now ordered my new AC slash heatpump, to be installed. There was no pressure, just me asking questions and I loved what he had to say. Perfect gentleman."

"My boiler in Wolfeboro NH failed suddenly. It was old and needed to be replaced anyway but I was hoping to get another season out of it. I called quite a few boiler companies and had difficulty even getting someone to answer the phone. Then I lucked out. I called Ed Grant and he answered his phone. It was November and getting cold. He came out to the house promptly and very professionally installed my new boiler. Not only is this guy honest, straight forward but he is such a hard worker. He worked diligently until the job was up and done. Absolutely no headaches, no bullshit, and not a salesman whatsoever. Ed Grant is the REAL deal if you need a new heating system. I would hire him again in an instant without a worry. A+. Thanks, Ed Brian Whitehouse"

"It went great, Tyler noted that I was handicapped and made sure that my new toilet was ADA approved. I felt it was a nice detail that many would have overlooked. Tyler paid great attention to detail, my bathroom was as clean after the new toilet was installed as it was before and even having to drag the old one through the house my hard wood floors never got a drop of water on them. He was friendly and very polite. I would definitely call him for our plumbing needs again!"

"I was disappointed. It seemed like a switched deal. You advertised $49.99 as the price for air ducts and everything and when he came out here, he quoted me the price of over $200. He said that it was just vents and he wanted to do everything so I was just disappointed with him. I bargained with him and said that I did not want all the returns so I ended up paying $150 on top of the $50 that I had already paid. If I wanted both the returns it was going to be $100 above that.He knew that it was an Angie's List big deal purchase and he still charged me more than what the big deal was for. I know that he did pull dust out of the air duct and they were cleaned. He arrived on time, he was a young kid, obviously he wasn't the owner of the business or anything like that.I think that if that fee that is advertised on the Angie's List website isn't the correct fee, that needs to be disclosed upfront. The price wasn't unreasonable. It was regular if I had just called somebody out of the blue, but when you gave me that big deal price, I assumed that was it. I would not use this provider again in the future."

"I was impressed with his knowledge and his ability to explain his thoughts to me as we were reviewing what needed to be done to install a replacement propane water heater He scheduled the project right away and came in the time frame designated, finish the work and also did extra functions that had to be done to allow the equipment to get into my basement. He followed up to make sure everything was working well and offered to come back in a day or two if I needed assistance. His billing was easy and professional. We are hoping to have him back again next year to do some HVAC work."

Install Boiler FAQs, answered by experts

Propane is more cost-efficient than natural gas on a per-unit basis because it produces twice as much heat energy as an equivalent amount of natural gas. But propane is not ideal if you already have a gas line installed. The best choice for your home depends on the efficiency of your appliances and the amount of installation required of your fuel choice.

A home radiator works by using radiation and convection to transfer heat throughout your home. Electric radiators use metal to conduct heat and warm the air, which then rises to warm the room. Steam and hot water radiators work with a boiler and piping system to pump thermal energy throughout the home. Hot water radiators use a boiler to heat the water before circulating it to the radiator, while steam heating radiator systems convert the heated water to steam before circulating it out. When the water or steam cools, it travels back to the boiler to be heated again.

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

The average lifespan of a boiler is typically between 15 and 20 years, though some may last for as little as 10 years while others can reach 30. A boiler's longevity is influenced by several factors, including the quality of the unit, proper installation, and consistent professional maintenance.

The material also plays a significant role. Older boilers made from durable cast iron can last for over 20 years, with some functioning for up to 50 years. However, it's important to consider their lower efficiency, which can lead to higher utility bills. Modern boilers, often made from steel alloys, are designed to withstand high pressure and temperatures and have an average lifespan of about 20 years.

To maximize your boiler's lifespan, ensure it is installed correctly, have it professionally maintained each year, and address any necessary repairs immediately.
