Seven months of heat, and nights near 29 degrees
Crossville needs a working furnace from October through April. That's seven months out of the year, with winter lows averaging 29°F. A new furnace here has to hold up to a long season of real work, not just a few cold snaps.
Cumberland County has seen its share of winter storms and damaging wind, and almost half of homes here heat with electricity. When the power goes out, a gas furnace with a standing pilot keeps running, but most furnaces need electricity to run the blower and controls no matter what fuel they burn. If you're installing a new gas furnace, federal rules require it to reach at least 80 percent AFUE, so the fuel you pay for turns into heat in your house instead of going up the flue.

- What size furnace does my house need?
- The right size depends on your home's square footage, insulation, window count, and ceiling height, not just a chart. A furnace that's too big will short cycle, heating the house fast and shutting off before it runs long enough to warm evenly. One that's too small will run constantly and still leave rooms cold on a 29°F night. A contractor works this out with a load calculation, which looks at your actual house rather than a rule of thumb based on square footage alone.
- How do I know it's time to replace my furnace?
- If your furnace is struggling to keep up on cold nights, cycling on and off more than it used to, or needing repairs every winter, it's worth having someone look at whether replacement makes more sense than another fix. An older furnace works harder to do what it used to do easily, and that shows up in your gas use before it shows up as a breakdown. Since homes here need heat from October through April, a furnace that's failing partway through that stretch is a bigger risk than one that fails in the warmer months. Uneven heating, rising bills for no clear reason, or a yellow flame instead of blue are all signs worth having checked.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and what furnace you have now. Every non-weatherized gas furnace made since November 2015 has to hit at least 80 percent AFUE, so even a standard replacement today burns less gas than an older unit did. A high-efficiency furnace goes beyond that minimum, which matters more here since homes need heat for 7 months of the year. A contractor can walk you through the difference in equipment and venting between the two, since high-efficiency furnaces vent differently than standard ones.
