A system built for eleven months of work
In Crossville, a new furnace or heat pump runs from October through April, and the air conditioner takes over from June through September. Only one month goes by without either one working. Winter nights average 29°F, cold enough that the heat runs most nights for seven months straight. Summer afternoons average 83°F, which is warm but not extreme, so the cooling side isn't carrying the same load the heating side is.
Nearly half the homes here heat with electricity, which means the equipment has to be sized right for those winter lows, not just the mild days on either side of the season. Cumberland County has also seen 10 winter storms and 54 damaging wind events over the past ten years, and across Tennessee, 20% of households went at least 24 hours without power in 2024. Whatever gets installed should be able to come back on and run correctly the moment power is restored, without anyone having to reset or relight it by hand.

- When should I replace my HVAC system?
- Replace it when repairs keep coming back, when the unit is old enough that parts are getting hard to find, or when it can no longer keep the house comfortable on the coldest or hottest days. A furnace or air conditioner nearing the end of its life tends to run longer to hit the same temperature, and the jump in energy use is usually the first sign something is wrong. With homes here needing heat or cooling 11 months of the year, a system on its last legs does not get much of a rest to hide the problem. If a contractor has already told you a major part is failing, that is usually the point where replacing makes more sense than repairing again.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, it usually makes sense to replace them together. A furnace and air conditioner installed at different times are often mismatched in age, and when one fails the other tends to follow within a year or two. They also share the same blower and ductwork, so replacing both at once lets a contractor size the whole system correctly instead of fitting a new piece to an old one. If one unit is much newer than the other, though, there is no reason to replace something that still has years left in it.
- What happens during an HVAC installation?
- A contractor removes the old furnace, air conditioner, or both, and sets the new equipment in place, connecting it to the existing ductwork, gas line or electrical circuit, and the vent or exhaust. They check the ductwork for leaks or sizing problems while everything is open, since new equipment that is more efficient can end up performing worse if it is forced through undersized or leaky ducts. Once it is connected, they test the system through a full cycle, checking airflow, temperature rise, and that the thermostat is talking to the new unit correctly. The exact steps depend on what is being replaced and how the old system was set up, so a contractor can walk through what your specific installation will involve.
