Oversized“Bigger is better” is a pretty poor attitude to have when selecting a furnace. Furnaces that are oversized put out far more heat than the home is able to handle. This leads to the thermostat often shutting the furnace down before it’s able to complete its full heating cycle, a behavior called “short cycling.” Prolonged short cycling drastically increases the amount of wear and tear on the furnace, causing various parts to start wearing out and eventually leading to a full breakdown.
UndersizedUndersized furnaces have just as many problems as oversized furnaces do. An undersized furnace cannot generate enough heat to keep the home in which it is installed at a comfortable temperature. So, it simply stays on for an extended period of time, trying in vain to keep the home warm enough to satisfy the thermostat. This causes just as much wear and tear as short cycling, and eventually the undersized furnace will break down just as surely as an oversized furnace would. If you want your furnace to last as long as possible, you need to make sure that it’s sized properly for your home.
