Oil Boiler Replacement and Installation

Trust Main Stream Mechanical to provide Massachusetts and New Hampshire with oil boiler installations that residents and commercial facility owners have relied on since 1996.

Time for an oil boiler replacement? Looking to upgrade or covert to a natural gas system? With all the options and configurations available, how can you know which is right for you and your home or facility? Main Stream Mechanical can help.

From planning to layout design, equipment selection to installation, our technicians have the experience necessary to keep Massachusetts and New Hampshire warm when it matters most. Over the years, we have seen it all and done it all. This unparalleled familiarity with oil boilers means that you, the customer, derive benefits from our industry knowledge that you just can't get anywhere else.

The advantages of oil heat are many, and include:

  • Efficiency - Oil heat systems typically perform at 85 - 95% efficiency
  • Quick-warming - An oil heat flame burns 300 degrees hotter than natural gas, which makes it the fastest-heating source around.

Additionally, in more rural areas of the states, natural gas lines may simply not have been dug, and may not be financially feasible depending on how far away you are from a gas grid. Since oil is stored in tanks and delivered by truck, in some cases it is just more abundantly available than natural gas.

Why Trust Main Stream Mechanical with Your Oil Boiler Services?

Commitment to Quality

Massachusetts requires HVAC contractors to be licensed. Still, many other companies hire unlicensed technicians that fail to match our standards of quality. Unlike these contractors, Main Stream Mechanical is fully licensed to ensure the highest quality services for our customers.
