What Size Mini-Split System do I Need?

July 21, 2017

Whether you have an add on to your home that seems to be a little hotter than the rest of the house or you’re simply looking for an efficient way to boost your home’s comfort, a mini-split system might be the choice.

What’s a mini-split system?
A mini-split system is a ductless form of heating and cooling that focuses on specific rooms and spaces, not an entire home or building. Mini-split systems are more flexible and energy efficient than normal central air systems and are easy to install because there is no ductwork required. They pump air right to wall or ceiling mounted air handling units that have individual wireless electronic temperature control systems.

Mini-split systems aren’t only one size, nor are they all created equally, or for the same size room. Comparable to traditional air conditioners and furnaces, a mini-split system should be sized to fit the room that it will be heating and cooling. Doing so can mean more efficient production for you, which could also lead to savings on your regular energy expenses as well. They’re normally used for:

  • Hot and/or cold rooms
  • Additions/renovations
  • Enclosed patios
  • Homes with no room for ductwork
  • Large, multi-zone living spaces

Your local experts at Pardee Service Experts Heating & Air Conditioning are well-versed in mini-split system sizing and will be able to provide you with choices based on the size of space that you’re looking to heat and cool.

A quick primer
A mini-split system functions by utilizing a process that only generates the amount of hot or cold air that you need to achieve or maintain the temperature you pick. That being said, a properly sized system is still critical to receive all of the efficiency benefits possible.

When it comes to sizing a mini-split system, our team recommends the top choice for you as we do with all of our heating and cooling equipment. We work directly with you to decide your needs and get the size of the room the system will be heating and cooling. A mini-split system that is too small will end up operating more often, meaning you’re wasting energy all the time. However, if your system is oversized, you’ll likely be spending more on the system and run the risk of having your mini-split system turning on and off all the time.
