HVAC Short Cycling? You May Have An Oversized Furnace or AC

When your HVAC is too large for your home, it can cause cycling problems. When you move to a new place or are looking for a new HVAC unit, you’ll need to make sure your system is a good fit for the size and layout of your home.

What Size AC Unit or Furnace Unit Do I Need?

When it comes to HVAC systems, your home needs a unit that’s just right. If your system is too small, your home will get too hot, and if it’s too large, your HVAC might short cycle. So, you need a unit that fits the dimensions of the space it's working in. Having an oversized AC or an oversized furnace can be just as big of an issue as having an undersized one.

How To Check For An Oversized AC or Furnace Unit

  • See if the setpoint temperature matches the room temperature.

  • Check when your system turns on and off. Most digital thermostats are factory set to run the system 6 cycles per hour. If your system turns on and off more often than every 10 minutes, your system might be oversized.

There are other reasons why a furnace or air conditioner might short cycle. Consider issues for a furnace or air conditioner that keeps turning on and off to rule out an oversized system.
