The HVAC Ratings You Need to Know
Keeping your home energy efficient is one of the best ways to save money on your monthly utility bills. But understanding how efficient your HVAC (heating, ventilation, air conditioning) system actually is can benefit you in the long run when it’s time to schedule professional service or even unit replacement. To determine efficiency, there are several HVAC ratings homeowners need to know:
“AFUE” – Annual Fuel Utilization Efficiency
This is the rating assigned for measuring the fuel efficiency of your furnace, but does not count the electrical energy required to run furnace controls, fan or pump. You can find the AFUE rating on the EnerGuide label on your furnace, and the higher it is the more efficient your furnace is.
“BTU” – British Thermal Unit
This is one of the main ways to measure the heating and cooling abilities of your equipment. It is the measurement of how much heat will be required to raise 1 pound of water by 1 degree Fahrenheit. If your furnace has a higher BTU, it has a higher heating capacity and therefore a higher efficiency.
“MERV” – Minimum Efficiency Reporting Value
This is how an air filter’s efficiency is measured. The rating measures the size of particles your filter can remove compared to the amount of particles the filter can remove. You want a filter that can remove large amounts of the smallest particles possible, like dust and other tiny pollutants. The higher the MERV value, the more efficient your air filter.
“SEER” – Seasonal Energy Efficiency Rating
Although next summer feels very far away, your air conditioner’s SEER rating is definitely one of the HVAC ratings you need to know. This rating is found by dividing the total cooling output in an average cooling season by the total electrical output in the same period. Your air conditioner’s SEER is also calculated in BTUs. The higher the SEER rating, the more efficient your unit.
