"I would recommend this company to everyone. Loved they are a small local, family owned business. Our furnace-boiler went out on a Saturday, Monday morning they were out and a quote in the afternoon. They made sure we had heat before Thanksgiving day. Very professional, knowledgeable, great craftsmanship. Best price on comparable equipment out of 3 quotes. Thank you!!"

"I had an excellent experience with Scott! Very friendly and extremely knowledgeable. During the thermostat installation procedure he discovered two issues with my AC unit (one of the fuses was blown and also one of the wires was fried) and fixed both without any additional cost. Very happy with the service and will definitely be using them in future. Thanks Scott!"

Install Boiler questions, answered by experts

Costs range from $3,000 to $7,500, depending on system size and efficiency.

You can save money on heating oil through a combination of improving home efficiency and smart purchasing strategies.

Home Efficiency and Usage:

  • Improve Insulation: Ensure your home, especially the basement and attic, is well-insulated and sealed against drafts to prevent heat leakage.

  • Manage Your Thermostat: Use a properly calibrated and programmable thermostat. Lower the temperature by a few degrees, particularly when you are away from home or asleep.

Purchasing Strategies:

  • Buy in the Off-Season: Order heating oil during the summer months when prices are generally at their lowest. This strategy is most effective if you have a large primary tank or a separate storage tank to accommodate bulk deliveries.

  • Consider a Delivery Contract: Some companies offer contracts with a set price for the term. This can lead to savings if market prices for oil increase, but you might pay more if prices drop.

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.

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.

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.
