It is possible to try and place shady trees around the condenser, but keep in mind that condensers also require good surrounding airflow for best efficiency. Use this calculator to estimate the cooling needs of a typical room or house, such as finding out the power of a window air conditioner needed for an apartment room or the central air conditioner for an entire house. If the room is a perfectly-square 20 feet by 20 feet, the total area would be 400 square feet. If its too big, youll be paying for extra heating capacity you never use.

Or in more pleasant weather conditions, simply exchanging the inside air with fresh, outdoor air. Therefore, 12 x To find the desired change in temperature to input into the calculator, find the difference between the unaltered outdoor temperature and the desired temperature. Even dirty white roofs (with noticeably darker shades) compared to newer, cleaner surfaces resulted in noticeable differences. Very Cold, The first two are merely rules of thumb that are often handy during our conversations with customers. Thats a 100F temperature swing! The number of watts = area x 10.
