Keep Cool and Save Energy
During the good ol’ summer time, you may be looking for a new central air conditioning unit to keep you cool.
Most homes have a central air conditioning unit with a 10 SEER (Seasonal Energy Efficiency Rating). By choosing a new Energy Star qualified unit with a SEER of 14, you can reduce CO2 emissions by about 1,540 pounds annually, assuming it’s on for 1,320 cooling hours, or 8 hours a day for 5-6 months. And make sure that your contractor does the sizing calculations so you don’t install a unit that’s too big. It will cost more and require larger ducts to handle its higher airflow. The unit also may fail to provide the expected comfort.
