What Size is Right For You?
Mini Split Sizing Calculator
Sizing your mini split system correctly is a vital step towards ensuring your comfort. If it is too small, you'll find yourself wasting energy while your unit runs and runs, all the while never reaching that temperature you desire.
If it is too big, not only will you have spent more money than necessary to start with, but you'll likely experience temperature swings and decreased energy efficiency throughout the life of your system. In both cases, you risk damaging your equipment due to inappropriate operating conditions.
If you give us a call, our degree-holding engineers are happy to provide a complete, professional sizing for your space at no cost to you. Because of the detailed work involved, these sizings take about 3-5 business days to complete. If you can't wait that long, or would just like a rough sizing estimate so you know where to start, you can use our online mini split sizing tool. Our proprietary software will lead you through some brief, yet specific, questions about your space and provide the best sizing estimate you'll find from an online tool. If you're looking to buy a multi-zone system, use the tool once per zone to get sizing estimates for each indoor unit (outdoor unit sizing for multi-zone systems may require additional calculations beyond the tool's capability).
