Choosing the right size ductless mini split system

Choosing the right size ductless mini split system


Mini splits are a great option for heating and cooling your home. Did you also know they're extremely efficient? They use inverter technology that enables your system to generate only the amount of heating or cooling needed to maintain the desired temperature. Even so, you'll want to be sure the system is properly sized for your home.

Although energy-efficient, if the system is too small, you'll find yourself wasting energy while your unit runs continuously, all the while failing to keep you comfortable in extreme conditions. This lack of performance will leave you on the hunt, yet again, for a better solution.

On the other hand, if the system is too large, you'll spend more on equipment and throw any energy savings out the window. Oversized equipment will also fail prematurely due to short cycling (turning on and off frequently).

The bottom line is this: Improperly sized equipment leads to decreased comfort, lower efficiency, increased service costs, and premature failure.

Want A Custom-Tailored Mini Split System?

Mini splits are sized in BTUs (British Thermal Units), which measures the amount of heat needed to raise the temperature of one pound of water by one degree Fahrenheit.

Call us today and our experienced engineers are happy to provide a complete, professional sizing for your space at no cost to you.


Why Are Some Systems Measured in Tons?

Often times, you'll see central air systems measured in tonnage. While this term sounds like a measurement of weight, it has nothing to do with weight at all. Tonnage is a term used in the HVAC field that describes how much heat the system can remove from the indoor air in one hour.

Mini-splits aren't measured in tonnage as well as central systems because they are sized to smaller spaces. Instead, mini splits are typically measured in BTUs (British Thermal Units). This is a much more universal system of measuring a condenser's ability to heat and cool an indoor area. You can convert tonnage to BTUs (1 Ton = 12,000 BTU) if you'd like to compare the two.
