Will an air conditioner with higher BTU cool my room faster?

BTUs determine how much cold air comes out of the unit, but problems can occur if the air conditioner is oversized for the space. The more cold air that comes out – the more area it needs to circulate to avoid giving the thermostat a false reading. If the unit is oversized, the cold air bounces off the wall back onto itself giving the thermostat a false reading – causing the compressor to shut off because the thermostat reads that the set temperature has been achieved. While the unit is off – the thermostat is able to read the room’s actual temperature, which kicks the compressor back on. This process will continue, causing the compressor to cycle off and on every two to three minutes, but never staying on long enough to effectively cool the room or remove uncomfortable humidity. Use the BTU calculator to find the correct amount of BTUs for the area you would like to cool. This chart can also be used as a general guide. When cooling rooms with poor insulation, great rooms, or southern or western sun exposures, step up to the next BTU size.
