Are you considering the install of a new central air conditioner in your Boston condo? You can save energy and money – and stay cool- by buying an energy-efficient model.
Today’s most efficient air conditioners use between 30 and 50 percent less energy that models from 30 years ago to generate the same amount of cooling. Even if your air conditioner is only ten years old, replacing it may save you up to 40 percent in energy costs.
Consider these factors when shopping for a new central air conditioner.
Proper Sizing – Match the right unit to cool your home efficiently. A unit that’s too large will not adequately remove humidity, and one that is too small won’t cool enough on those oppressively hot days.
Season Energy Efficiency Ratio (SEER) – This measure indicates the relative amount of energy needed to provide a specific cooling output. Look for a model with a high SEER (much like you should look for a window air conditioner with a high ER). Many older systems have a SEER of 6 or lower. Residential central air conditioners made since January 2006 must have a SEER of 13 or higher.
Unit location, insulation, duct installation, and other factors also affect air conditioning efficiency. An experienced contractor can recommend a system that’s best for your Boston condo.
