Seven months of heat, most of it from the grid
Your new furnace will run from October through April here, seven months of the year. Winter nights average 30°F, cold enough that the furnace is cycling on and off most of the night to hold the temperature.
63.1% of homes here heat with electricity, so when a winter storm knocks out power, the furnace goes down with it. The area has seen 11 winter storms and 126 damaging wind events over the past ten years, and 20% of Tennessee households went at least 24 hours without power in 2024. Any furnace installed new has to meet the federal minimum of 80 percent AFUE.

- What size furnace does my house need?
- The right size comes from a load calculation, not a chart based on square footage alone. A contractor measures your insulation, window area, ceiling height, and how much outside air leaks in, then sizes the furnace to match. A furnace that's too big will short cycle and wear out faster. One that's too small will run constantly and still leave rooms cold when it's 30°F outside. Since homes here need heat from October through April, getting this number right matters for most of the year.
- How do I know it's time to replace my furnace?
- Watch how often you're calling for repairs and how evenly the house heats. Once a furnace needs attention every heating season, replacement usually costs less over time than another repair. Uneven heat between rooms, a furnace that runs longer to reach the same temperature, or a yellow flame instead of blue are all signs the unit is struggling. If yours is already acting up and winter lows here average 30°F, a contractor can tell you whether it's worth fixing again or time to replace it.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and what you're already paying to heat it. Every new non-weatherized gas furnace sold today has to reach at least 80 percent AFUE, but high-efficiency models go higher than that, meaning less fuel is lost out the vent. With 63.1% of homes here heating with electricity, the math on switching or upgrading depends on your current setup and local rates. A contractor can run the numbers for your specific house before you decide.
