Furnaces come in a variety of sizes to meet the demands of different styles of homes. Although it might seem to make sense that “bigger is better” when it comes to furnaces, the truth is that your home can suffer from many issues if your furnace is too large. Today we’re going to explain why this is the case by talking about common problems associated with oversized furnaces!

Common problems caused by an oversized furnace

  • Your home will be uncomfortable. When your furnace is too big, it will blast your home with too much conditioned air at one time. This can make your rooms feel too warm when your furnace is operating and lead to major temperature swings in your home. In addition, the rooms that are far away from your furnace will likely not receive enough warm air because the area around your thermostat will heat up too quickly and your furnace will shut down before every room is properly heated.
  • Your furnace will short cycle. When a furnace is too powerful for the home it’s installed in, it will go through very quick heating cycles because your home will heat up too quickly. This puts your furnace through a whole lot of wear and tear, which will dramatically increase the likelihood of your system breaking down.
  • Your heating bills will be expensive. Your furnace consumes the most amount of energy when it is starting and heating up. If your system is oversized and short cycling as described above, it will spend much more time in “startup mode,” which will force it to consume more energy and lead to high heating bills.
  • Your system won’t last as long. When you consider the amount of excess wear-and-tear that an oversized furnace goes through, it shouldn’t be surprising to learn that oversized furnaces do not last nearly as long as properly-sized systems.
