Seven months of heat, and nights that drop to 22°F

Parkville homes need a working furnace from October through April. That's seven months of the year, and on the coldest nights the average low is 22°F. A furnace here doesn't get much of a break between seasons.

Most homes in the area heat with gas, and any new gas furnace has to meet a federal minimum of 80 percent AFUE if it was built after November 19, 2015. Platte County has also seen its share of winter storms and wind, the kind that knock out power and put extra strain on a heating system already working through a long, cold season.

What size furnace does my house need?
There's no single number that fits every house, because it depends on your square footage, your insulation, your windows, and your ceiling height. A furnace sized too big will short cycle and wear out its parts faster. One sized too small will run constantly through the cold months and still leave you cold. A contractor works this out with a load calculation, not a guess based on the house next door.
How do I know it's time to replace my furnace?
Age is the first sign. Older furnaces start costing more to repair than they're worth fixing, especially once parts begin failing one after another. Watch for uneven heat between rooms, a burner flame that's yellow instead of blue, or a furnace that cycles on and off more than it used to. With 7 months of heating season here and winter nights averaging 22°F, a furnace on its last legs will show its age fast once the cold sets in.
Is a high-efficiency furnace worth it?
For a house that needs heat from October through April, it usually pays to look at one. Every non-weatherized gas furnace made since November 2015 has to hit at least 80 percent AFUE, so that's the floor, not the ceiling. High-efficiency models push well past that, and with most homes here heating with gas, the difference shows up over a winter that runs long and cold. A contractor can walk you through which efficiency level makes sense for your house.
