Power and efficiency
First, it’s important to select the correct air conditioner size. A small unit you use over a long period of time is more efficient than an air conditioner that is too powerful and that you constantly start and stop. Also, remember that a room with a lot of natural light needs a more powerful air conditioner. For adequate air quality and comfort, it’s best to opt for a longer operating cycle, which yields a lower humidity level. An appropriately sized air conditioner maintains a relative humidity level of 30% to 50%, which is really comfortable. Energy efficient performance is also worth considering before making a final decision. Check the EnerGuide label to learn about the performance of each unit. The higher the SEER (seasonal energy efficiency ratio), the more energy efficient the model.
Individual or central
Choosing the right air conditioner depends mostly on the space that needs to be cooled. For one or two rooms, a single unit is fine. Choose a window air conditioner, which is convenient and economical for a small area, or a mobile or portable device on wheels. For the latter, however, installing a hot air vent to the outside is required, not to mention regularly emptying the tank of condensation water. If, on the other hand, you want to cool the entire house, you should set your sights on a wall-mounted heat pump. Among the wide range of models offered, some wall units are designed for homes that do not have an air duct (forced air heating) system. Wall-mounted heat pumps, for example, consist of a compressor and a condenser installed outside the house. Furthermore, a fresh air diffuser is placed at the top of a wall, centrally in the space to be air conditioned to ensure consistent freshness. Et voilà! With all this in mind, you’re well informed to make the right choice to combat the summer heat.
