The best way to determine the correct air conditioner size for your home is to choose a reputable installer. At Tetra, we calculate your home’s cooling needs based on industry standards. These calculations take the climate and your home’s size, design, and construction into account. An air conditioner that’s too small for your home will struggle to cool your space. If your air conditioner is too large, it cools your home so quickly that it doesn’t have time to remove enough moisture from the air. This leaves your home feeling cold and clammy.
ENERGY STAR helps easily identify high-quality, energy efficient products. To earn the ENERGY STAR, a product, like an air conditioner, must meet strict energy efficiency criteria set by the US Environmental Protection Agency or the US Department of Energy. Products with the ENERGY STAR logo are generally 15% more efficient than the minimum federal standards. ENERGY STAR products help you save on your monthly bills and help the planet by reducing energy usage.
Cooling load is the rate at which heat must be removed from your space to maintain a constant temperature and humidity. Your home’s cooling load depends on its size, construction, insulation, number of windows, and other factors. The cooling load will also determine the size and model air conditioner your home needs.
