What Size Mini-Split System do I Need?

July 21, 2017

Whether you have an add on 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 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 is focused on specific rooms and spaces, not an entire home or building. Mini-split systems are more adjustable and energy efficient than traditional central air systems and are easier to install since there is no ductwork needed. They pump air right to wall or ceiling mounted air handling units that have individual 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 picked to fit the area that it will be in. Doing so can mean more efficient production for you, which might also mean savings on your normal energy expenses as well. They’re usually 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 Donelson Air Service Experts are well-versed in mini-split system calculations and can provide you with options 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 you desire to get to or maintain the temperature you have set. That being said, a properly sized system is still important to reap all of the efficiency benefits offered.

Mini-split system sizing
When it comes to measuring for a mini-split system, our experts 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 area 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 over time. However, if your system is too large, you’ll probably be spending more on the system and have the risk of having your mini-split system turning on and off constantly.
