Parkville asks a lot from a new system, both ends of the year
Winter nights here average 22°F from December through February, and a furnace runs from October through April, seven months of the year. Summer afternoons average 87°F, and the air conditioner has its own five months, May through September. Between the two, there are only a few weeks in spring and fall when the system gets to rest.
Most homes in the area heat with gas, and whatever gets installed has to meet the federal minimum efficiency rating in place now. Weather is part of the picture too. Ten winter storms and 68 damaging wind events have hit this area over the past ten years, and in 2024, 19% of Missouri households lost power for at least 24 hours. A new system is worth putting in right the first time, since it has a long stretch of hard weather ahead of it either way.

- When should I replace my HVAC system?
- Replace it when repairs stop making sense, when the system can't keep up on the coldest or hottest days, or when breakdowns start happening every year. A furnace that short cycles or an air conditioner that's low on refrigerant is telling you something. Homes here need heat or cooling all year, so there isn't much slack time to put off a decision. Watch for rising repair calls and rooms that won't hold temperature. Those are signs the equipment is wearing out, not just having a bad week.
- 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 the same time are matched to work as one system, and pairing new equipment with something much older can mean the newer unit never runs at its best. It also means one visit instead of two down the road. But if one unit is much newer than the other, there's no reason to replace it early just to match. A contractor can look at the age and condition of each and tell you what makes sense for your house.
- What happens during an HVAC installation?
- A contractor removes the old furnace, air conditioner, or both, and sets the new equipment in place, connecting it to the existing ductwork, gas line or electrical, and refrigerant lines. They check that the ducts are sized right for the new unit, since a furnace or air conditioner that's too big or too small for the ductwork won't heat or cool evenly. Once it's connected, they test the system, checking airflow, refrigerant charge, and that the thermostat is talking to the equipment correctly. On a house with gas heat, which covers most homes here, they'll also check the gas connections and venting before leaving. The exact steps and how long it takes depend on the equipment and the house, so a contractor can walk through specifics for your setup.
