Ten months of work a year, in Shelby County heat and cold
Your furnace and your air conditioner don't get much rest here. Winter nights average 34°F from December through February, and summer afternoons hit 90°F from May through September. Homes in Shelby County need heat from November through March and cooling from May through September, which adds up to ten months a year one system or the other is running.
More than half the homes here heat with electricity, so a new system needs to handle both jobs well, not just the summer heat. Storms are part of the picture too. Shelby County has seen 195 damaging wind events and 15 winter storms over the past ten years, and last year one in five Tennessee households lost power for at least a day. A new installation is worth planning around that, not just around the weather on a calm afternoon.

- When should I replace my HVAC system?
- Replace it when repairs start coming often, or when a contractor tells you the compressor or heat exchanger is failing, since those repairs usually cost more than they're worth. Age matters too. Most furnaces and air conditioners last 15 to 20 years, and past that point parts get harder to find. If your system is old and the next repair is a big one, that's usually the sign to stop patching it and replace it instead of waiting for it to fail on a 34°F night or a 90°F afternoon.
- Should I replace my furnace and air conditioner at the same time?
- If they're close in age, yes, it's worth doing together. A furnace and air conditioner installed at the same time are matched to work as a pair, and replacing one while the other is much older often means mismatched equipment that doesn't perform as well. It also means one installation instead of two, which is easier on the house and the ductwork. If one unit still has real life left in it, a contractor can tell you whether it makes sense to wait or replace both now.
- What happens during an HVAC installation?
- A contractor removes the old furnace and air conditioner, or whichever equipment is being replaced, and checks the ductwork, refrigerant lines and electrical connections before putting in the new unit. The new equipment gets set in place, connected to the ducts, wiring and, for gas furnaces, the gas line. Once it's running, the contractor tests it, checks refrigerant charge and airflow, and sets the thermostat before walking you through it. A contractor will price and schedule the job based on your specific house.
