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 on the lookout for an efficient way to improve your home’s comfort, a mini-split system could be the way to go.

What’s a mini-split system?
A mini-split system is a ductless form of heating and cooling that focuses on individual rooms and spaces, not an entire home or building. Mini-split systems are more flexible and energy efficient than common central air systems and are easier to install because there is no ductwork needed. They pump air directly to wall or ceiling mounted air handling units that have separate 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. Much like common air conditioners and furnaces, a mini-split system should be picked to fit the room that it will be responsible for. Doing so can mean more efficient production for you, which could also mean savings on your regular energy costs as well. They’re normally used for:

  • Hot and/or cold rooms
  • Additions/renovations
  • Enclosed patios
  • Homes without space for ductwork
  • Large, multi-zone living spaces

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

A quick primer
A mini-split system functions by employing a process that only generates the amount of hot or cold air that you need to reach or maintain the temperature you choose. That being said, a correctly sized system is still crucial to reap all of the efficiency benefits available.

Mini-split system sizing
When it comes to sizing a mini-split system, our team recommends the top product for you as we do with all of our heating and cooling equipment. We work directly with you to decide your needs and measure the size of the area the system will be heating and cooling. A mini-split system that isn’t big enough will end up working more often, meaning you’re wasting energy all the time. However, if your system is too large, you’ll likely be spending more on the system and run the risk of having your mini-split system flipping on and off frequently.
