Time for gas furnace service? Maybe you require repair or routine maintenance before the Massachusetts and New Hampshire temperatures really start to drop. Main Stream Mechanical can help. Since 1996, we've been building relationships with homeowners and commercial facility owners and establishing a reputation of trust that they can rely on for all their heating needs.

Gas furnace maintenance is typically recommended as an annual service. After all, maintenance is preventative. Think of your gas furnace like your car; the longer you put off a routine service check, the more likely your vehicle is to require expensive– and usually avoidable– repairs in the future.

But it can be difficult to know, sometimes, just when your gas furnace is in need of repairs. Telltale warning signs can include:

  • Noise - Gas furnaces are typically quieter than other types of systems. Unexpected knocking or rattling may indicate a mechanical problem, clogged burner, or airflow reduction.

  • Malfunctioning Thermostat - A faulty thermostat can make it difficult to accurately gauge room temperature, or heat a room to your preference.

  • Reduction of Heat - If your gas furnace doesn't seem to be heating as well as usual, you may have a clogged filter.

  • Frequent Cycling - This may also indicate a clogged filter, as well as a mechanical problem that might require a more thorough examination of the unit.

Why trust Main Stream Mechanical with your gas furnace repairs?

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.
