How to Choose the Right Furnace for Your Great Falls Home
Not all furnaces are built the same—and not all homes in Cascade County need the same system. Our experts help you sort through options like:
Gas Furnaces
A popular, cost-effective option for most homes
Electric Furnaces
Better for homes without natural gas access
High-Efficiency Furnaces
ENERGY STAR® models with 90–98% AFUE ratings
We’ll explain the differences in performance, price, and long-term savings. Live in a draftier historic home near downtown Great Falls? We’ll factor that in. Upgrading from an older oil or boiler system? We’ll walk you through what to expect.
Want to maximize energy efficiency? Pair your new furnace with a smart thermostat to better control temperature and cut down on energy use.
