Is Bigger Always Better for Furnaces?

Is Bigger Always Better for Furnaces?

October 3rd, 2022


If you’re shopping for a furnace right now, chances are that you’re not in too much of a rush, since we’ll still have our warmer and more humid weather for a while. But we have had customers who have rushed into a purchase like this, because they don’t necessarily understand the importance of getting the exact right furnace for their specific living space.

Unfortunately, rushing into a purchase like this can actually leave you with a furnace system that is too big for your home. That’s right, bigger isn’t always better, at least not when it comes to your home comfort systems.

The size of your furnace can actually have a big impact on its functionality as well as its efficiency. It is important that you work with qualified professionals to ensure that your home is getting matched up with the exact right furnace for your specific needs. Read on to learn why.

Always Work with a Pro

Proper sizing is just part of the reason that it’s so important you have your furnace installed by a trained and experienced professional. Installing a furnace isn’t a simple job by any means. It requires skills and even proper licensing–this is especially important if it’s a gas-powered furnace being installed.

Why You Don’t Want Your Furnace to be Undersized

As you can probably imagine, an undersized heating system of any kind will not be able to properly provide your home with the warmth and comfort that you need. Your furnace will instead struggle and need to run longer than it would otherwise have to, just to keep up with the heating demands placed on it. This is understandably problematic when it comes to efficiency.

A furnace that is “overworked” like this is going to need repairs more frequently than it should, and it can succumb to wear and tear much quicker than an adequately sized heater. Overall, if a furnace is too small, it will cost you a lot more money to operate if you want to actually stay comfortable.

Why You Don’t Want Your Furnace to be Oversized

Now, onto why bigger isn’t always better… as we implied above, homeowners are often tempted to go with the biggest furnace their budget will allow, typically because they believe it will do the best job of keeping them comfortable throughout our brief yet chilly winters. But, and oversized (overpowered) furnace is prone to a number of issues, with the biggest one of these issues being short cycling.

Short cycling is the name we gave to the process where an HVAC system shuts on and off rapidly, never actually completing a full heating (or cooling) cycle. Short cycling only ever occurs for one of a few reasons:

  • The air filter needs to be changed.
  • There is an internal electrical problem that needs to be repaired.
  • The system installed is too big for the space.

Unless you have an older furnace and the short cycling just started recently, you’re probably looking at an oversized system being the culprit.
