compare.ac may earn a commission on purchases, at no cost to you. It never changes the price you pay or how we rank units.
Both units are scored on the exact same scale, from the manufacturer's own published specs and the live retailer price where we have one. Room fit uses the official ENERGY STAR sizing chart, or an estimate from cooling power when a maker publishes no coverage. Where the two efficiency scales are not comparable, we never crown a winner. Nobody can pay for placement.
