How to Cool a Small Room

Cooling a small room is an efficient way to manage energy. During the summer months, air conditioning is a common method to cool rooms, but it's also expensive and uses a lot of energy. If you need to use an air conditioner, take steps to maximize efficiency.

A ceiling fan is an easy way to cool a small room.

During winter months, the heat may be cranked up to sweltering levels. This is a waste of energy and requires that you cool rooms. No matter what room cooling situation is presented, you can take creative methods to control temperature.

  1. Maximize air-conditioner use by using high-efficiency room units with an energy-efficiency ratio above 10. For central air, efficiency can be upped to 12. Choose a model that eliminates humidity if you live in a moist climate. Multispeed air conditioners provide the best cooling options. Do not use a humidifier and an air conditioner at the same time. This will make your air conditioner work harder, putting strain on the machine.

  2. Install heat-reflecting film on windows that get direct sunlight. Not only will the film keep the room cool, it also will protect carpeting, furniture and other household objects from sun damage.

  3. Draw shades and blinds to reduce heat and avoid heat-generating activities, such as ironing, dish washing and laundry. If you must perform one of these activities, use a dehumidifier or ventilated fans to remove warm air. Keep doors closed and close vents to block warm air.

  4. Install a ceiling fan or window fan. A window fan circulates air through the room and does not require that interior doors be closed during use. This method only works if the circulating air is 77 degrees or lower.

  5. Plant trees and shrubs that will provide shade. Shade blocks hot sunlight, which may be a problem during cold winter months. In this case, choose vegetation that loses leaves during the winter. Determine the benefits and drawbacks of planting trees and shrubs based on your climate before making a decision. Decorate your home in light colors, such as white, beige and gray. Light colors reflect heat, while dark colors absorb it.

  6. Seal your home by insulating and weatherstripping it to control the transfer of cool and hot air. Detect air leaks beforehand to determine material and placement. There are many weatherstripping materials to choose from, including vinyl, tape, felt, foam, rubber and tension seals. By applying weatherstripping around windows and drafty areas, you can ensure better temperature control in the room you want to cool.

    Do not try to take all of these steps at once. Determine what is best for the room and your home first.
