Your system runs almost year round in Robertson County
Homes here need heat from October through April, seven months a year, and cooling from May through September. That leaves the system working all twelve months, with no long stretch where it just sits idle.
A new install has to handle both ends of that. Winter nights average 30°F from December through February, and summer afternoons average 88°F. Most homes here heat with electricity, so when a storm knocks out power, the heat goes with it. Robertson County has seen 11 winter storms and 126 damaging wind events over the last ten years, and one in five Tennessee households lost power for at least a day in 2024. That is worth planning around, not just the weather on a calm day.

- When should I replace my HVAC system?
- Replace it when repairs start happening every year or two, or when the system is old enough that a breakdown is more a question of when than if. Furnaces and air conditioners both lose efficiency as they age, so a unit that limps along is also costing more to run than it should. Homes here need heat or cooling all twelve months, October through April for heat and May through September for cooling, so there is no season where a failing system just sits idle. If a contractor tells you a repair costs a large share of what a new system would, that is usually the point to stop repairing.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, replacing them together is often the better move, but it depends on the condition of each one. A furnace and air conditioner installed years apart can still work together fine as long as they are matched properly. The main reason to do both at once is that they share parts of the same system, like the blower and ductwork, so a contractor can size everything correctly in one visit instead of two. If one unit is still young and working well, there is no need to replace it just because the other one failed.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace, air conditioner, or both in place, and connects them to the existing ductwork, gas line, electrical wiring, and refrigerant lines as needed. They check that the ducts are sized right for the new equipment, since a system that does not match the ductwork will not heat or cool evenly. Once everything is connected, they test the system, check refrigerant charge and airflow, and confirm the thermostat is working with the new equipment. A contractor can walk through the exact steps for your home once they know what is being replaced.
