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 looking 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 specific rooms and spaces, not an entire home or building. Mini-split systems are more flexible and energy efficient than traditional central air systems and are simpler to install as there is no ductwork required. They pump air straight to wall or ceiling mounted air handling units that have their own wireless electronic temperature control systems.

Mini-split systems aren’t only one size, nor are they all made equally, or for the same size room. Similar to common air conditioners and furnaces, a mini-split system should be picked to fit the room that it will be heating and cooling. Doing so means more efficient production for you, which might also translate to savings on your monthly energy costs as well. They’re normally used for:

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

Your local team at A-PLUS Service Experts Heating & Air Conditioning are well-versed in mini-split system calculations and will be 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 utilizing a process that only creates the amount of hot or cold air that you need to get to or maintain the temperature you pick. That being said, a correctly sized system is still critical to reap all of the efficiency benefits offered.

Mini-split system sizing
When it comes to sizing 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 get the size of the area the system will be heating and cooling. A mini-split system that isn’t big enough will end up running more often, meaning you’re wasting energy constantly. However, if your system is oversized, you’ll probably be spending more on the system and carry the risk of having your mini-split system flipping on and off constantly.
