What Size Mini-Split System do I Need?

July 21, 2017

Whether you have an addition 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 increase your home’s comfort, a mini-split system could be the choice.

What’s a mini-split system?
A mini-split system is a ductless form of heating and cooling that is focused on individual rooms and spaces, not an entire home or building. Mini-split systems are more adaptable and energy efficient than traditional central air systems and are simpler to install since there is no ductwork needed. 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 one-size-fits-all, nor are they all made equally, or for the same size room. Similar to normal air conditioners and furnaces, a mini-split system should be chosen to fit the room that it will be responsible for. Doing so could mean more efficient production for you, which may also translate to savings on your monthly 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 team at Norrell Service Experts are experienced in mini-split system sizing and are able to provide you with choices based on the size of space that you want to heat and cool.

A quick primer
A mini-split system functions by employing a process that only creates the amount of hot or cold air needed to reach or maintain the temperature you pick. That being said, a properly sized system is still important to get all of the efficiency benefits possible.

Mini-split system sizing
When it comes to determining size for a mini-split system, our team recommends the best product for you as we do with all of our heating and cooling equipment. We work directly with you to figure out your needs and measure the size of the space 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 oversized, you’ll likely be spending more on the system and run the risk of having your mini-split system flipping on and off frequently.
