Understanding the way your home comfort systems run and their efficiency is critical to keeping your whole home energy efficient and saving on your monthly utility bills. When you learn how to read your system’s various HVAC ratings, you’ll be able to make decisions based on efficiency easier when it comes to investing in repairs or purchasing new units.
To determine efficiency, there are 4 HVAC Ratings every homeowner needs to know:
AFUE – Annual Fuel Utilization Efficiency
This rating is assigned to measure the fuel efficiency of your furnace. It does not count the electrical energy that your furnace requires to run its controls, pump or fan. The AFUE Rating is located on the EnerGuide label on your furnace. The higher the AFUE rating, the more fuel-efficient your furnace is.
BTU – British Thermal Unit
This is the unit of measurement used to gauge the heating and cooling ability of your system equipment. A BTU is the measurement of how much heat is required to raise 1 pound of water by 1 degree Fahrenheit. The higher the BTU on your furnace, the higher its heating capacity and therefore it should be performing at a higher efficiency.
MERV – Minimum Efficiency Reporting Value
This rating informs you of your air filter’s efficiency. It’s found by measuring the size of particles your filter is able to remove from the air compared to the amount of particles it removes. A filter that removes large amounts of the smallest particles possible is best, so the higher the MERV value, the more efficient and effective your air filter.
SEER – Seasonal Energy Efficiency Rating
Summer may have come and gone, but SEER is still one of the most important HVAC ratings for homeowners to know and understand. SEER is used to measure your air conditioner’s efficiency. It’s found by dividing the total cooling output in an average cooling season by the total electrical output in the same seasonal period. The number is calculated in BTU’s and the higher the SEER rating, the more efficient your air conditioner.
