Whenever you look for AC installation in Portland, you should look for the Seasonal Energy Efficiency Ratio, or SEER rating, of your new air conditioning unit. As you can see in this video, the SEER rating will usually be located on the energy guide located on the unit, or you may be able to find it on the manufacturer’s website.
SEER ratings are used to measure the efficiency of an air conditioning unit or heater over a season. The higher the SEER rating, the more efficient that unit will be over time. To be sure you have the most efficient unit, it is recommended that your unit’s SEER rating is at least 13 or higher.
