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

What’s a mini-split system?
A mini-split system is a ductless form of heating and cooling that is focused on specific rooms and spaces, not an entire home or building. Mini-split systems are more adaptable and energy efficient than normal 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 separate wireless electronic temperature control systems.

Mini-split systems aren’t just one size, 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 sized to fit the area that it will be heating and cooling. Doing so means more efficient production for you, which may also mean savings on your normal energy costs as well. They’re usually used for:

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

Your local pros at Coastal Service Experts are knowledgeable in mini-split system sizing and are able to provide you with specific products based on the size of space that you want to heat and cool.

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

Mini-split system sizing
When it comes to measuring for a mini-split system, our team recommends the top option 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 working more often, meaning you’re wasting energy over 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 all the time.
