Murfreesboro asks a furnace to run seven months a year
From October through April your furnace is the thing standing between your family and a 31°F night. That's seven months of regular work, not just a few cold snaps. A new furnace installed here needs to hold up to that stretch, year after year.
Most homes in Rutherford County heat with electricity, and the power doesn't always stay on. Tennessee saw 20 percent of households lose power for 24 hours or more in 2024, and the last ten years brought 9 winter storms and 137 damaging wind events through this area. A furnace that starts back up on its own when the power returns matters here. Any gas furnace installed today also has to meet the federal minimum of 80 percent AFUE, so you're starting from a baseline that already puts more of your fuel into heat instead of waste.

- What size furnace does my house need?
- The right size comes from a load calculation, not the square footage of your house alone. A contractor measures your insulation, window count, ceiling height, and layout, then runs those numbers to find the size that matches your home. A furnace that is too big will short cycle, turning on and off before it heats evenly, and one that is too small will run constantly and still leave rooms cold. Homes here need heat from October through April, so getting this number right matters for the whole season, not just the coldest nights.
- How do I know it's time to replace my furnace?
- Watch for repairs that keep coming back, uneven heat between rooms, or a furnace that is old enough that parts are wearing out together. A cracked heat exchanger or a failing control board often costs more to fix than a new furnace costs to install, and a contractor can tell you which situation you are in. Winter nights here average 31°F, so a furnace that struggles now is more likely to fail on one of the coldest nights than a mild one. If you are already scheduling repairs more than once a season, that is worth acting on before winter gets deep.
- Is a high-efficiency furnace worth it?
- It depends on how you heat now and how long you plan to stay in the house. Every non-weatherized gas furnace built since November 19, 2015 has to reach at least 80.0 percent AFUE, so even a standard replacement today is already fairly efficient. A high-efficiency furnace goes further, turning more of the fuel it burns into heat instead of losing it out the flue, which matters most for a house that needs heat for 7 months of the year the way homes here do. Most homes here heat with electricity, so a contractor can walk you through how a gas furnace's efficiency rating would actually apply to your situation.
