High efficiency air conditioners can be great for saving on summer energy bills, but to get your air conditioner to perform up to its seasonal energy efficiency ratio (SEER) rating, a number of things need to be in place. Air conditioners receive their SEER rating based on the results of testing. They are ensured favorable operating conditions during this testing, so you’ll want to provide the same for them in your home.
To get your air conditioner’s cooling to where it’s needed your home needs ductwork, and for high efficiency performance, this ductwork needs to be well-designed and well-installed. The combination of your ductwork’s resistance to airflow and your air handler determine the airflow across your air conditioner’s cooling coils. If airflow rates are too low, your air conditioner’s efficiency will take a hit. To avoid this, the resistance to airflow of your ductwork should be minimized by including as few turns as possible and by using appropriately sized ducts. It also needs to be well-sealed against air leakage so that cool air doesn’t get wasted by escaping the ductwork before reaching the air registers.
It’s also important to provide appropriate run times. Relative to the amount of cooling provided, turning off and on uses more energy than steady operation, so you don’t want your air conditioner to only run for brief periods of time. Larger air conditioners don’t have to run as long to cool your home, so to get the best run times without being uncomfortable, you’ll want an air conditioner whose cooling capacity is equal to your home’s cooling needs on the hottest summer days. To find out what those needs are, you’ll need to have a contractor perform a detailed cooling load calculation using Manual J from the Air Conditioning Contractors of America (ACCA).
The last key to good performance is a quality installation. Any errors, such as an incorrect amount of refrigerant charge, will be detrimental to how efficiently your system performs.
