What Are the Energy Efficiency Ratings to Look for in Central AC Units?
When evaluating central air conditioning units for energy efficiency, several key ratings are important to consider:
- SEER (Seasonal Energy Efficiency Ratio): The SEER rating measures the cooling output of an air conditioner during a typical cooling season divided by the total electric energy input. Higher SEER ratings indicate more energy-efficient units, with modern systems typically ranging from 14 to 25 SEER, significantly reducing electricity costs over time.
- EER (Energy Efficiency Ratio): The EER is similar to SEER but is calculated based on a specific set of outdoor temperatures, usually 95°F. This rating helps consumers understand the efficiency of the unit under peak conditions, making it essential for areas with extreme heat. A higher EER reflects better performance in hot weather.
- HSPF (Heating Seasonal Performance Factor): Although primarily associated with heat pumps, the HSPF rating indicates the efficiency of heating during the winter months. It measures the total heating output during the heating season divided by the total electricity consumed, with higher ratings signifying better efficiency for units that also provide heating.
- ENERGY STAR Certification: Products that meet the ENERGY STAR criteria are independently certified to save energy and reduce greenhouse gas emissions. Choosing an ENERGY STAR-rated central AC unit ensures that it performs at least 15% more efficiently than non-certified models, providing peace of mind regarding energy efficiency.
- AFUE (Annual Fuel Utilization Efficiency): While more relevant for furnaces, AFUE can also be a consideration if the central AC unit is part of a combined heating and cooling system. This rating measures the efficiency of fuel use in heating appliances, and although it is not directly applicable to air conditioning alone, it can indicate the overall efficiency of a system in heating and cooling.
What Common Issues Should Buyers Expect with Central AC Units?
Buyers of central AC units should be aware of several common issues that can arise during their use.
