How You Can Know If You Have an Energy Efficient AC Unit

Not every air conditioner is an energy efficient AC unit. For example, the age of the specific unit matters. Since air conditioner efficiency has improved steadily over time, a unit manufactured 10 years ago is almost certainly less efficient than today’s new model. Another aspect is the quality and regularity of maintenance. Annual preventive maintenance by a professional HVAC contractor ensures that all AC components are functioning up to the manufacturer’s specifications, including the unit’s energy-efficiency rating.

Here are some additional factors that determine whether you have an energy efficient AC unit:

  • Efficiency rating. Air conditioners are manufactured to meet specific Department of Energy standards, expressed as SEER (Seasonal Energy Efficiency Ratio) ratings. The higher the SEER rating, the more cooling the unit generates per kilowatt hour of electricity. Standard efficiency units are SEER 13 or 14, while high-efficiency units can range as high as SEER 25.
  • Right sizing. An AC unit’s “size” in this context refers to its BTU cooling capacity relative to specific characteristics of the residence. Too little or too much capacity can degrade air-conditioner energy efficiency and cooling effectiveness for as long as the unit is installed. Before choosing a new air conditioner, a sizing calculation should be performed by a certified HVAC technician to determine the home’s exact cooling requirements and match it to a new unit that provides the appropriate cooling capacity.
  • Rising operating costs. Most people have a notion of how cooling costs typically affect their monthly electricity bill. If these costs begin to increase in the absence of other explanations, such as an unusually hot spell or utility-price hikes, it may be a sign that your air conditioner is no longer meeting energy-efficiency specs and may no longer be an energy efficient AC unit. This decline may be due to you neglecting regular maintenance, a malfunction, or normal wear and tear related to the age of the unit.
