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 might be the choice.

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 adjustable and energy efficient than common central air systems and are easy to install since there is no ductwork involved. They pump air straight 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 produced equally, or for the same size room. Similar to traditional air conditioners and furnaces, a mini-split system should be sized to fit the room that it will be in. Doing so could mean more efficient production for you, which might also translate to savings on your normal energy bills as well. They’re typically 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 Parker Pearce Service Experts Heating & Air Conditioning are knowledgeable in mini-split system sizing and can provide you with choices based on the size of space that you’re looking to heat and cool.

A quick primer
A mini-split system operates by using a process that only creates the amount of hot or cold air needed to reach or maintain the temperature you have set. That being said, a properly sized system is still crucial to receive all of the efficiency benefits possible.

Mini-split system sizing
When it comes to determining size for a mini-split system, our experts recommends the ideal product 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 space the system will be heating and cooling. A mini-split system that isn’t large enough will end up running 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 carry the risk of having your mini-split system turning on and off frequently.
