What Size Ductless System do I Need?

TechXpert verified by Ken Kontra

The size of your ductless system will depend on the size of your home. The sizing of your ductless system is very important. So you’ll want to make sure to pick the right size that works most efficiently for your home.

Finding the Right Fit

Like most home appliances and systems, you want the best fit for your home. If your ductless system is incorrectly sized and positioned, it can interfere with functions like humidity control and leave you with unnecessarily high electric bills. So it’s important to select the right size based on what your home truly needs.

Factors for Sizing

The size of your ductless system will depend on:

  • Number of areas you want to cool

  • Number of air handlers

  • Existing insulation levels

  • BTU requirements

The most important factor is the number of areas you want to heat and cool. This will determine the capacity (and the relevance of the remaining factors).

Seize the Size

If you’re not sure how to size your ductless system, you should contact an HVAC technician who can make sure your system is perfect for your home. With the right size, you can seize the opportunity for more efficiency, all year round.
