A furnace is a heating system that generates heat by burning fuel, such as natural gas, oil, or propane, and then distributes warm air through ducts to heat the living spaces in a building.

We had a great experience from start to finish! The installers were professional, courteous, prompt, efficient, as well as clearly knowledgeable and experienced. We appreciated how considerate they were of the fact they were in our home. They took time to answer any questions we had and for whatever explanations were needed. And we love having central AC!!

Frequently asked questions

What is the Mass Save program?

How do I know what size furnace is right for my home?

The best way to determine the correct furnace size for your home is to choose a reputable installer. At Tetra, we calculate your home’s heating needs based on industry standards. These calculations take the climate and your home’s size, design, and construction into account. A furnace that’s too small for your home won’t keep your house comfortable in extremely cold weather. Most furnaces are slightly bigger than necessary to avoid this possibility, but a furnace that’s too large will cycle on and off more frequently. This causes wear and on the components, uncomfortable fluctuations in temperature, and noisy airflow—not to mention, it wastes a lot of energy.

What are "zones"?

A zone is an are in your home, which is controlled by its own thermostat. A home can have anywhere from 1-5 zones based on size, layout, or additions. Zoned HVAC uses dampers in the ductwork to regulate and redirect air to specific areas of the home.

What is “heat load”?

Heat load is the amount of heat energy your home needs in order to maintain the desired indoor temperature. Your home’s heat load depends on its size, construction, insulation, number of windows, and other factors. The heat load will also determine the size and model of furnace your home needs. Speak to one of our experts about the new furnace cost and the best furnace for your home.

How long does a furnace typically last?

The lifespan of a furnace can vary depending on factors such as maintenance, usage, and quality of installation. On average, a well-maintained furnace can last 15-20 years or more.
