What a system in Maury County has to handle
Your new system needs to run all twelve months here. Heat from October through April, seven months, then cooling from May through September, five months. Winter nights average 30°F, and summer afternoons average 88°F, so whatever you install has to handle both ends with little break in between.
Most homes here heat with electricity, so the furnace or heat pump you choose carries the load on those cold nights on its own. Maury County has seen 9 winter storms and 104 damaging wind events over the past ten years, and in 2024, 20% of Tennessee households lost power for a full day or more. Whatever you install, it should come back on by itself once the power does.

- When should I replace my HVAC system?
- Replace it when the repairs start piling up or the unit is old enough that another breakdown is just a matter of time. Most furnaces and air conditioners last a decade or two, and once a system is in that range, a major repair often costs enough that putting the money toward a new system makes more sense. Watch for rooms that will not heat or cool evenly, a system that runs longer than it used to, or a repair bill that comes close to what a new unit would run. With heat needed October through April and cooling needed May through September here, a system that is struggling has almost no season off to recover in.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, that is usually the better time to do it. A furnace and air conditioner installed together are matched to work as one system, and replacing one now and the other in a few years can mean the newer unit is stuck pairing with parts it was not designed to run alongside. It also means only one round of labor and one time the system is down instead of two. If one unit is much newer than the other, a contractor can look at both and tell you whether it makes sense to wait or replace them together.
- What happens during an HVAC installation?
- A contractor removes the old furnace and air conditioner, or heat pump, and sets the new equipment in place, then connects it to the ductwork, refrigerant lines, gas or electrical supply, and the thermostat. They check the ductwork itself for leaks or damage before closing everything up, since even a new system will not heat or cool well through bad ducts. Once it is connected, they run the system through a full cycle, check refrigerant levels and airflow, and confirm the thermostat is talking to the equipment correctly. A contractor can walk you through what your specific installation will involve.
