Importance of a Properly Sized Furnace

Importance of a Properly Sized Furnace

It used to be a common practice to install a system with a higher heating capacity. A lot of people are tempted to opt for the largest furnace they can afford in the hopes of keeping their house warm in winter. However, bigger is not always better. This is especially true when it comes to heating systems.

When choosing a furnace for your home, it is important to get one that is properly proportioned to your home. Otherwise, it will do the opposite of what you want it to do.

Here are 3 reasons why furnace size is so important.

Longer furnace life

If the furnace is too big for your space, it will heat your space quickly. Your furnace will shut off once it reaches the desired temperature. Once the temperature starts to drop, it will turn back on again. The equipment will constantly turn on and off in an attempt to maintain the desired temperature. This can put additional strain to your system and may shorten the life of your furnace.

Energy efficiency

Furnace size is a very important consideration when it comes to energy efficiency. An undersized furnace will cost more to operate. Since the furnace doesn’t have enough output to heat a space that large, it will be forced to work harder and run longer. And since most people keep their heating system turned on 24/7 in winter, you may find yourself with a skyrocketing bill.


An appropriately sized furnace can provide adequate amount of heat into your living space; thereby, allowing your family to stay warm and toasty throughout the winter. If the furnace is too small, however, your home may not be adequately heated. It may not be strong enough to reach all of the rooms, so you may have an uneven temperature in your home.
