Air conditioners must be sized by the number of BTUs they can remove from the air in the space they cool. Ratings are commonly measured in tons (1 ton = 12,000 BTUs). When selecting a properly-sized air conditioner, room size is not the only relevant factor. Amount of sunlight exposure, insulation quality, and the number of room occupants should also be taken into account.
While it may be tempting to oversize an air conditioner to make sure there will always be enough cooling power, there are downsides to this approach. An air conditioner that is too large will cycle on and off more frequently. It will not permit optimal energy efficiency and won't allow the unit to remove as much humidity from the room. Air conditioners will dehumidify most effectively when they run for longer periods of time. Visit SupplyHouse.com for all your air conditioning and mini-split needs this summer.
