Eleven months of the year, this system doesn't get a break
Winters here bring nights averaging 30°F from December through February, and summer afternoons climb to 84°F. Heat runs October through April, seven months, then cooling takes over June through September, four more. A new furnace or heat pump has to handle that long winter stretch, and the condenser has to keep up through the summer heat.
Most homes here heat with electricity, so a power outage means no heat too. Sevier County has seen 68 winter storms and 157 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 sized for both the cold nights and the heat, and set up to come back on its own once the power does.

- When should I replace my HVAC system?
- Once your furnace or air conditioner is old enough that repairs keep coming back, or one has actually failed, it's time to replace it. Age alone isn't the only sign, but a system near the end of its life will start needing more frequent fixes. With heat needed here from October through April and cooling from June through September, there's not much of the year when either system can sit broken for long. If a repair bill is on the table, ask the contractor what replacing it now would mean instead of paying for another fix.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, replacing them together usually makes sense, but it depends on the condition of each one. A furnace and air conditioner installed at the same time were matched to work together, and pairing a new unit with one that's much older can mean they don't run as well together as they should. It also means dealing with one installation instead of two separate ones down the road. If one system is much newer than the other, a contractor can tell you whether it's worth keeping for now.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace and or air conditioner in place, and connects it to your ductwork, gas line or electrical circuit, and condensate drain. They'll also check the ducts and refrigerant lines to make sure they're sized right for the new equipment, since a system built for one house doesn't always fit the ductwork already in another. Once everything's connected, they run the system to check refrigerant charge, airflow, and that it cycles on and off the way it should. Ask the contractor walking through your job what order they'll do things in and how long they expect it to take, since that varies by house.
