A new system has to handle both ends of the year in Raymore
Winter nights average 24°F from December through February, and a new furnace needs to hold the house warm through that without strain. Summer afternoons run 87°F, and the air conditioner paired with it has to keep up on those days. Between the two, homes here need heat or cooling every month of the year, seven months of heat from October through April and five months of cooling from May through September.
More than half the homes here heat with gas, and whatever system goes in has to be sized for both jobs, not just one. Cass County has seen 9 winter storms and 89 damaging wind events over the past ten years, and statewide, close to a fifth of households lost power for at least 24 hours in 2024. That is worth knowing when you are choosing a system and deciding what happens to your heat or your air conditioning if the power goes out.

- When should I replace my HVAC system?
- Replace it when repairs get frequent, when the system is old, or when it can no longer keep the house comfortable through the cold months and the hot ones here. A furnace working harder than it used to, or an air conditioner that cycles constantly in summer, is telling you something. If a contractor has already been out more than once this year for the same unit, that is usually your answer. Homes here need heat from October through April and cooling from May through September, so there is no real off season to put the decision off.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, replacing them together usually makes sense. A furnace and air conditioner installed at different times often do not match well, since the blower, the coil, and the furnace are designed to work as a set. If one is still fairly new, a contractor can tell you whether it is worth pairing with a new unit now or waiting until it needs replacing too.
- What happens during an HVAC installation?
- A contractor first sizes the new equipment to the house, since a furnace or air conditioner that is too big or too small will not heat or cool evenly. The old equipment comes out, the new furnace or coil goes in, and the refrigerant lines, ductwork connections, gas line, and electrical are all hooked up to it. The contractor then tests the system, checks the refrigerant charge, checks for gas leaks if it is a gas furnace, and confirms the thermostat is working with the new equipment. A contractor will walk through the specifics for your house and give you a timeline before the work starts.
