"I had a great experience with this company installing my new boiler. Their pricing was fair compared to other estimates I received. Dave walked me through the entire process and answered all my questions, and his team came in and did a great job with the installation. With so many scammers out there, I truly felt comfortable working with this company and will absolutely use them again in the future."

"the process was better than I expected. The sale man knew what he was talking about . The installation crew had worked for the company a long time and were also very knowable . When we could not understand a few things they sent out a serviceman just to show us how it works. They also directed us towards financiers and reabate availability."

"Great Experience with Kevin guiding us with the proposal of a Central Air and Furnace replacement. Very professional and answered all questions timely. No hard sell at all. We did have an existing Lennox AC. The install team of Shakil, Ty and Brandon were just as professional. True to their proposal, they came in and installed both systems in one day. Left the area neat and clean."

Install Boiler FAQs, answered by experts

Yes. In many cases, switching from an old furnace to a high-efficiency boiler can help you save money over time. You can also save money by switching from an electric boiler to a gas boiler, which costs much less compared to the energy bills an electric boil can create. Boilers are often (but not always) more efficient than furnaces, too. Then there are discounts, rebates, and incentives that can help you save on the initial costs.

Generally, an oil furnace is considered safer than a gas furnace for several reasons. While both types of furnaces can produce carbon monoxide, a leak in an oil furnace is easier to detect due to the smell. Oil furnaces also don't connect to a gas pipeline, which reduces the chance of a fuel leak. Most importantly, heating oil is not combustible, whereas natural gas is highly flammable. This means there is a much lower risk of combustion or explosion with an oil furnace. However, an oil furnace can still pose a fire hazard if it tips over.

If your boiler is 20 years old, it’s time to get a new one. Although it may seem to be working fine, it’s likely eating up more fuel than it should. Also, compared to a brand-new boiler, one that’s 20 years old is probably not working as well. When you get your new unit, you’ll notice that your home is heating more quickly, and the heat is consistent throughout all the rooms.

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

The best time to buy home heating oil is in the summer when the demand is lowest, as the prices are usually lower. However, waiting until the summer to buy is often unavoidable unless you install a separate storage tank. If you have the space for a second tank, you can expect to pay between $1,000 and $4,000 for the oil tank replacement or installation, depending on the capacity and location. You could quickly recuperate these costs, though, by stocking up on heating oil in the summer and avoiding deliveries in the winter when prices are highest.
