A system that has to work almost every month of the year
Jasper County only gets a few weeks off. Winter nights average 27°F from December through February, and a new furnace or heat pump has to keep pulling heat out of that cold air for seven months, October through April. Then summer flips it around, with afternoons averaging 88°F for five months straight, May through September. That is 12 months a year of one system or the other running.
A lot of homes here heat with electricity, which means the furnace or heat pump you install is also drawing on a grid that Missouri has had trouble keeping up in bad weather. The last ten years brought 9 winter storms and 124 damaging wind events to the area, and statewide, close to one in five households lost power for a full day or more in 2024. Whatever gets installed needs to hold up through both the heat and the cold, and start back up cleanly once the power does.

- When should I replace my HVAC system?
- Once your furnace or air conditioner is old enough that a breakdown is a real risk, and repairs keep coming up, replacement is the safer call. Homes here run the furnace October through April and the air conditioner May through September, so there is almost no month where either one can sit broken for long. If a contractor tells you a repair will hold, that is fine, but once they start saying it a second or third time, that is your answer.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, replacing them together is usually the better move. A furnace and air conditioner installed at different times often were not matched to work together, and a contractor putting in a new system can size the furnace and coil to fit each other and your ductwork. It also means one visit and one warranty instead of two, which matters here since something is running almost every month of the year.
- What happens during an HVAC installation?
- A contractor first sizes the new equipment to your house, checking the ductwork, insulation, and the square footage being heated and cooled. Old equipment comes out, including the furnace or air handler, the outdoor condenser, and any coil or line set that is being replaced. New equipment goes in, gets connected to your ducts, wiring, and refrigerant lines, then gets tested and checked for the correct airflow and refrigerant charge before the contractor walks you through it.
