Davidson County runs its system all year
Your new system needs to heat from October through April and cool from May through September. That is 12 months where one side or the other is working, with barely a break between them. Winter nights average 31°F, and summer afternoons average 88°F, so neither side is coasting when it runs.
Most homes here heat with electricity, so the furnace or heat pump you choose has to handle real cold, not just take the edge off. Davidson County has also seen 462 damaging wind events and 10 winter storms over the past ten years, and in Tennessee last year one in five households lost power for at least a day. A system that comes back on by itself once power returns matters here.

- When should I replace my HVAC system?
- Look at the age and the repair history more than any single breakdown. Furnaces and air conditioners both start running into trouble after ten years or so, and if yours is in that range and needs a repair, replacing it is usually the better move. Frequent breakdowns, rising bills with no clear cause, and rooms that never get comfortable are all signs the system is wearing out rather than having a bad week. Homes here need heat or cooling every month of the year, so a system on its last legs does not get much of a break to fail quietly.
- Should I replace my furnace and air conditioner at the same time?
- If they are close in age, replacing them together often makes sense, but it depends on the condition of each one. A furnace and air conditioner installed at the same time tend to wear out around the same time too, so if one is failing the other is usually not far behind. They also share the blower and ductwork, so matching them keeps everything working the way it was designed to. A contractor can look at both systems and tell you whether replacing one now and planning for the other later makes sense for your house.
- What happens during an HVAC installation?
- The old furnace or air conditioner comes out, and the new one goes in along with any parts that need to match it, like a new coil or thermostat. The contractor connects it to your ductwork, gas line or electrical circuit, and refrigerant lines if it is an air conditioner or heat pump. Once it is running, they check the airflow, the refrigerant charge, and the thermostat settings to make sure the system is working the way it should. A full installation covers both the equipment and the connections around it, not just swapping one box for another.
