A split is a structural change that needs a certified installer and usually permission. We track 81 rules across 16 regions, so you find out before the box arrives.
Straight answers with a real recommendation, sized and priced from the same live data as the tool.
The units people actually cross-shop, side by side with an honest verdict on which fits your room.
Only real air conditioners
Every unit here removes heat with a refrigerant cycle. No tower fans, no evaporative coolers dressed up as AC.
One honest spec scale
Cooling, noise, energy rating and the room it covers, normalized so two units are actually comparable.
We never invent a number
A spec the manufacturer does not publish stays blank. Prices come live from the retailer, not a guess.
Not sure which to pick?
Tell us your room and your situation. We will suggest the right system type and cooling power, then point you straight at the matching units. No jargon, no upsell.
Answer four things, see what actually fits.
