A system that has to work both ends of the year
In Sedalia, heat runs October through April and cooling runs May through September. That is 12 months of the year with one or the other on. Winter nights average 24°F from December through February, so a furnace or heat pump has to hold the house at temperature on the coldest nights, not just take the edge off. Summer afternoons average 86°F, and the air conditioner answers for that heat for five straight months.
Pettis County has logged 8 winter storms and 47 damaging wind events over the past ten years, and in 2024, 19% of Missouri households went at least 24 hours without power. A new system here should be installed with both seasons and those outages in mind, since it is asked to run nearly all year.

- When should I replace my HVAC system?
- Replace it when repairs start piling up or the system can't keep up on the coldest winter nights and hottest summer afternoons anymore. An older unit that needs a major repair is usually a better candidate for replacement than another fix. Rising energy bills with no other explanation, uneven temperatures room to room, and short-cycling are all signs the equipment is wearing out rather than having a bad week. A contractor can look at the age, the repair history, and how the system is running now to tell you whether it's worth fixing again or time to replace it.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, replacing them together often makes sense, but it depends on the condition of each one. Homes here run the furnace October through April and the air conditioner May through September, so both units work hard every year and tend to age at a similar pace. A furnace and AC installed at different times can also end up mismatched, which affects how evenly the system heats and cools. A contractor can check the age and condition of both and tell you whether replacing one now and planning for the other makes more sense than doing both at once.
- 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, and refrigerant lines. They check the ductwork for leaks or sizing problems, since a new system connected to bad ducts won't perform the way it should. Once everything is connected, they test the system, check refrigerant charge and airflow, and confirm the thermostat is working with the new equipment. The exact steps depend on whether it's a straight swap or a bigger change, like switching fuel types or resizing the ductwork, so a contractor will walk through what your specific installation involves.
