Gas Furnaces


A properly maintained furnace can provide you with years of comfort and warmth during those long winter months here in Massachusetts. But how do you choose the right one for your home?

The size of your Westford, MA, home, type of fuel source, and energy efficiency are the three main factors when it comes to purchasing a furnace. Keep those factors in mind to help make your selection.

Since 1978, Basnett Plumbing, Heating, AC & Electrical has installed, repaired, and maintained furnaces in homes throughout MetroWest Boston and surrounding area. We work with all makes and models and offer preventative maintenance plans to ensure your comfort on the coldest of days.

When it comes to heating, ventilation, and air conditioning (HVAC) systems, count on your team at Basnett Plumbing, Heating, AC & Electrical to keep your equipment operating at peak efficiency.

Furnace Installation

Most furnaces run on natural gas because it is widely available and tends to be the most economical choice, but oil and electricity are two other options.

A properly sized furnace delivers warmth and comfort without wasting energy and overworking itself. Our professionals will calculate the square footage in your home and how well each room is insulated to determine the right size furnace for your needs.

You also want to consider the annual fuel utilization efficiency (AFUE) rating of your furnace. A furnace with a 95 percent AFUE rating can convert 95 percent of the energy it consumes into heat.

The higher the AFUE, the more money you save on energy bills. Keep in mind that well-maintained air ducts and properly sealed windows and doors are key factors in energy efficiency.

Furnace Repairs

If you ever detect an issue with your furnace, our expert repair team will quickly pinpoint the problem and fix it. There are many moving parts to a furnace, and you can trust one of our licensed professionals to get the job done correctly and safely. You can also count on us for emergency service repair calls.

Furnace Maintenance

Whenever you invest in your HVAC system, it only makes sense to maintain it. Doing so ensures you get the maximum efficiency and service life out of your equipment. It can also keep you in compliance with its manufacturer’s warranty, should you ever need to make a claim.

Our Ultimate Maintenance Plans make it easy to keep your HVAC equipment running at peak performance. The best time to have your furnace checked is in the fall. Our professionals will perform a standard inspection and tune-up of your system, clean all the parts, and make any necessary adjustments.

How Much Money Can a New Furnace Save You?

Our AFUE energy savings calculator can help determine how much you could save on your utility bills. Simply enter your current unit's AFUE value and compare it to a newer, more efficient system. You can even customize it to better match your home's system for a more accurate calculation.
