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 toastier than the rest of the house or you’re simply searching for an efficient way to boost your home’s comfort, a mini-split system could be the answer.

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 adjustable and energy efficient than common central air systems and are easier 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 one-size-fits-all, nor are they all produced equally, or for the same size room. Similar to common air conditioners and furnaces, a mini-split system should be sized to fit the space that it will be heating and cooling. Doing so can mean more efficient production for you, which may also mean 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 pros at Roy Inch & Sons Service Experts Heating & Air Conditioning are experienced in mini-split system sizing and will be able to 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 works by utilizing a process that only produces the amount of hot or cold air you desire to get to or maintain the temperature you pick. That being said, a appropriately sized system is still critical to reap all of the efficiency benefits possible.

Mini-split system sizing
When it comes to determining size for a mini-split system, our team recommends the top choice 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 room 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 run the risk of having your mini-split system turning on and off constantly.
