Frequently Asked Questions

Q. Which BTU would be good for my home?

You need to select an air conditioner that has a good BTU power and is capable of cooling your home efficiently.  For rooms under 500 sq ft, 8,000-12,000 BTU is ideal for fast cooling. For rooms that have a larger area to cool, opt for a device in the 14,000-25,000 BTU bracket. Smaller rooms under 200 sq ft won’t require much BTU power so 5000-6000 BTU will do well enough.  Remember that a larger BTU means faster cooling for small rooms. However,  this also means high electricity consumption and a bigger price tag for the air conditioner.
