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 on the lookout for an efficient way to boost your home’s comfort, a mini-split system may be the choice.

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 adaptable and energy efficient than common central air systems and are easy to install as there is no ductwork involved. 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 one-size-fits-all, nor are they all made equally, or for the same size room. Similar to normal air conditioners and furnaces, a mini-split system should be chosen to fit the area that it will be in. Doing so means more efficient production for you, which might also mean savings on your regular energy costs 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 Bob Brown Service Experts are knowledgeable in mini-split system calculations and will be 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 operates by employing a process that only generates the amount of hot or cold air needed to achieve or maintain the temperature you pick. That being said, a properly sized system is still critical to reap all of the efficiency benefits offered.

Mini-split system sizing
When it comes to determining size for a mini-split system, our team recommends the best product for you as we do with all of our heating and cooling equipment. We work directly with you to determine your needs and get the size of the space the system will be heating and cooling. A mini-split system that is too small will end up running more often, meaning you’re wasting energy all the time. However, if your system is oversized, you’ll possibly be spending more on the system and have the risk of having your mini-split system cycling on and off all the time.
