For millions of us, it’s just one of those conveniences we take for granted. We just assume when we hear that familiar hum on our way inside on a hot day that our air conditioner is hard at work making sure there’s relief inside. Most of us don’t stop to think about how our air conditioners work and the choices we need to make to replace one of these units until we need to. Here are a few things to take into account that will make sure you’re getting the best from the choices available. First, keep in mind that you should expect nothing less than top notch efficiency from the unit that you’re considering. Things have come a long way and you should expect to find a quiet unit that runs better than its predecessors and even saves on electrical bills. The unit’s Seasonal Energy Efficiency Ratio (SEER) is the gauge you can use to determine the product’s effectiveness. The higher the number, the more efficient the system is. In Canada there are government regulations that control the efficiency of any of the units that you can buy. These Energy Efficiency Regulations came into effect in 1995 and they see to it that a unit with a rating of 13 SEER is the lowest rating that can be sold. Units that are rated at 14.5 or higher will have an Energy Star label attached to tell you they have reached a premium level of efficiency helpful site. The EnerGuide rating system is another method you can use to compare the energy efficiency of different models on the market.
