What Size Mini-Split System do I Need?

July 21, 2017

Whether you have had a renovation 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 is has its focus on distinct 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 involved. They pump air directly to wall or ceiling mounted air handling units that have separate wireless electronic temperature control systems.

Mini-split systems aren’t one-size-fits-all, nor are they all created equally, or for the same size room. Similar 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 can mean more efficient production for you, which could 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 experts at Epperson Service Experts Heating & Air Conditioning are experienced in mini-split system measurements 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 employing a process that only creates the amount of hot or cold air you desire to reach or maintain the temperature you pick. That being said, a correctly sized system is still critical to receive all of the efficiency benefits offered.

When it comes to measuring for a mini-split system, our team recommends the best choice for you as we do with all of our heating and cooling equipment. We work directly with you to figure out your needs and calculate the size of the space the system will be heating and cooling. A mini-split system that is too small will end up operating more often, meaning you’re wasting energy constantly. 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.
