How to Choose the Right Unit
How to Calculate the Correct BTU
EXAMPLE: Mini-Split in a Kitchen
You have a 20' by 15' kitchen, that has 2 large windows facing the sun in the morning and the evening. Your ceiling is 10' high and the room usually has 2 people in it.
To estimate the BTU required to cool the space, the math would break down like this:
- Baseline square foot coverage:
20 x 15 = 300 sq. ft. = 9,000 BTU
- For kitchens, add in 2,000 BTU:
9,000 BTU + 2,000 BTU = 11,000 BTU
- For rooms with a lot of windows, increase BTU by 10%:
11,000 BTU x .10 = 1,100 + 11,000 = 12,10
- For ceilings higher than the standard 8 ft. height, increase BTU by 20%:
12,100 BTU x .20 = 2,420 BTU + 12,100 BTU = 14,520 BTU
- Add in 1,200 BTU to account for room occupants:
14,520 BTU + 1,200 BTU = 15,720 BTU
With all factors accounted for, to effectively cool your kitchen, you would need a: 18,000 BTU mini-split
Advantages of a Mini-Split
Great for unique air conditioning needs.
Mini-split systems are highly customizable and offer flexibility for the cooling or heating of individual spaces. They’re great for retrofitting into any pre-existing space that may not be able to have ducts added. They're also great for tiny homes where every inch of space is valuable. The possibilities are endless!
Compared to traditional central ac systems, mini-splits avoid much of the energy loss associated with ductwork, which can account for up to 30% of energy consumption in space heating/cooling. Equipped with inverter compressor technology, they conserve energy by using only enough power to reach and maintain desired set temperature.
Room temperatures can be customized to your needs.
With central air conditioning, individual spaces cannot be temperature controlled, but with mini-splits every space can have its own climate.
Improved air quality.
Air ducts should be professionally cleaned every 1-3 years, or more often if someone has special medical conditions. This cleaning can be expensive and with the added cost of central ac filters, maintenance can really start adding up. Mini-splits, on the other hand, have reusable filters that can be washed and placed right back into the unit.
