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 toastier 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 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 focuses on specific 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 as there is no ductwork involved. They pump air straight to wall or ceiling mounted air handling units that have individual 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. Comparable to common air conditioners and furnaces, a mini-split system should be chosen to fit the room that it will be heating and cooling. Doing so could mean more efficient production for you, which could also lead 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 space for ductwork
  • Large, multi-zone living spaces

Your local pros at Stevenson Service Experts Heating & Air Conditioning are knowledgeable in mini-split system calculations and are able to provide you with options based on the size of space that you want to heat and cool.

A quick primer
A mini-split system functions by utilizing a process that only produces 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 important to get all of the efficiency benefits offered.

Mini-split system sizing
When it comes to sizing a mini-split system, our team recommends the ideal choice for you as we do with all of our heating and cooling equipment. We work directly with you to determine your needs and measure the size of the room the system will be heating and cooling. A mini-split system that isn’t big enough will end up operating more often, meaning you’re wasting energy constantly. However, if your system is too big, you’ll possibly be spending more on the system and run the risk of having your mini-split system cycling on and off frequently.
