DIY Mini Split for a Bedroom: Quiet, Easy-Install Comfort by Zone Air
A DIY mini split for a bedroom gives you quiet, independent heating and cooling you can install yourself. Most bedrooms run 150–350 sq ft, so a 9,000 BTU system is usually the right fit — and Zone Air’s pre-charged design means no vacuum pump and no contractor.

What Size Mini Split for a Bedroom?
Sizing follows about 20 BTU per square foot. A 9,000 BTU mini split covers a 200–350 sq ft bedroom; smaller guest rooms and nurseries are well within range. Larger master bedrooms (350–550 sq ft) step up to 12,000 BTU. Zone Air systems run as low as 39 dB on the indoor head, so they stay quiet enough to sleep through. Run your room through the sizing calculator to be sure.
