HVAC efficiency is measured using several key ratings that determine how effectively your equipment uses energy. Here is a breakdown of the primary ratings used for heating and cooling systems:
SEER (Seasonal Energy Efficiency Ratio): This gauges cooling performance for air conditioners. Higher numbers indicate better efficiency, with ENERGY STAR certified models typically having ratings of 15 or higher.
SEER2: This is an updated testing standard introduced in 2023. It provides more realistic results by simulating cooler operating temperatures.
AFUE (Annual Fuel Utilization Efficiency): This rating is used for furnaces to measure how much fuel is converted into heat. For example, a 95 percent AFUE rating means 95 percent of the fuel is turned into heat for the home while 5 percent is lost.
HSPF (Heating Seasonal Performance Factor): This evaluates the efficiency of heat pumps. According to local experts, this rating is best balanced with SEER ratings for dual-fuel setups.
Understanding these ratings helps homeowners select energy-efficient systems that lower utility bills and improve indoor comfort. To maintain these ratings over time, it is important to perform regular maintenance such as changing air filters and scheduling professional tune-ups.
