The free what size mini split do I need calculator checks cooling and heating, then matches a model.
Looking for a 9000 BTU mini split (also written 9,000 BTU) that cools and heats without ductwork? Classic America's 9,000 BTU mini split is a 23 SEER2 inverter mini split heat pump sized for bedrooms, home offices, studios, and similar spaces around up to 400 square feet under typical conditions. It runs on 115V~/60Hz/1P — the class shoppers call a 110V / 120V mini split — so many homes can use a standard residential circuit for this capacity (confirm with a licensed electrician before you buy).
This hub focuses on our verified 9,000 BTU single-zone system: model MSCT-09HAC1, Tuya WiFi + Amazon Alexa on top of the included remote, Auto / Cool / Heat / Dry / Fan modes, and free freight in one box (indoor unit, outdoor unit, and install kit). Need more capacity? Compare our 12,000 BTU mini splits or run the free size finder. Prefer every 115V option in one place? See the 110V mini split hub.
Many homeowners treat mounting and line-set routing as a hybrid DIY project; Classic America still recommends a licensed HVAC pro for refrigerant and electrical connections — start with the delivery & installation guide and install planner. Warranty: 5-year compressor / 1-year parts. Questions? Call 1-800-349-4360 Ext. 204 (Mon–Fri, 10 AM–3 PM ET), Miami Gardens, FL.

Is a 9,000 BTU mini split the right size?
The 9,000 BTU system is rated for up to 400 sq ft under typical conditions — the ENERGY STAR chart puts 350–400 sq ft at 9,000 BTU with an 8 ft ceiling and average sun. A sunny room, high ceiling, poor insulation or a kitchen pushes the load up; a shaded, well-insulated bedroom pulls it down.
The free size finder adjusts for all of that, checks your winter heating load too, and tells you whether 9,000 BTU is enough or you should step up to 12,000 BTU.
Power
115V / 110V power for 9k systems
The 9,000 BTU system publishes 115V~/60Hz/1P, the same standard household class people call 110V or 120V. A licensed electrician should confirm the circuit before install. Every 115V system we sell is on the 110V mini split hub.
