Gas Furnace
Gas furnaces generate heat by burning natural gas. They’re available in varying sizes and energy efficiencies and produce a hot, dry heat. While still the most widely used furnaces, they’re starting to lose market share to electric models due to utility costs, environmental concerns and tax incentives.
Mitchell says gas furnaces are an excellent choice in regions with harsh winters due to their powerful heating capacity. He suggests looking at more than just the initial price when selecting a furnace. “Gas furnaces might have higher installation costs,” he says, “but they generally offer lower monthly running costs.”
Gervais agrees. Gas furnaces, he says, are “a smart choice in regions with cold climates and affordable natural gas.” He adds they “require a connection to the gas supply and regular maintenance to ensure safety and efficiency.”
How to identify a gas furnace
It’s easy: You’ll see a gas supply line and exhaust flues. Low-efficiency gas furnaces will vent to the roof, while higher efficiency models vent out to an exterior wall.
