Regular HVAC maintenance and repair is certainly one way to keep heating and cooling costs down over the years. But, according to Honolulu’s top HVAC service, 3-D Sheetmetal, it’s also critical to pay attention to the type of system you buy from the start. Specifically, you should be mindful of what type of energy efficiency rating a prospective system carries.

Energy efficiency rating, or EER, represents the amount of BTUs that are used each hour for every watt of power required to run the machine. The higher the EER, the more energy-efficient the appliance is, as it can produce more cooling power while using a lower wattage level. New systems typically have a sticker on the unit that indicates the specific rating.

How is SEER Different Than EER?

SEER stands for Seasonal Energy Efficiency Rating and is somewhat similar to EER. Essentially, the EER rating is calculated assuming that an appliance remains at the same temperature setting throughout its operating life. SEER, on the other hand, represents an average efficiency of the air conditioner as it is set at different temperatures.

Since SEER represents an average, the listed number may not always be the exact efficiency you get. As such, if you’re comparing individual products, SEER can be helpful. However, if you’re trying to calculate your energy expenses, EER provides a better point of reference.

Will Buying a Higher EER Always Save You Money?

Figuring out how much your new AC will save you depends on how often you use it and how much the initial purchase price is. Usually, when you buy a higher EER, you will pay more upfront and start recouping energy savings within a few years.

Other factors, however, can help you step up the energy efficiency of your home or business. For instance, you can consult with a heating and cooling specialist to see if HVAC repairs or air duct cleaning would be beneficial. And, if it’s time for you to get a new system, these same professionals can help you determine what system is best—and how much power it should operate to cool the space efficiently.
