If you are looking for a new heating and cooling system, you have to consider a lot of factors. Is it the correct size for your home? Is it energy efficient? How does the system work with your finances? Will the HVAC system be quiet enough for your house? What kind of air quality can you expect? It can be overwhelming. On top of all the questions you have, some HVAC knowledge seems just out of reach. The acronyms and shorthand that industry professionals use can create questions for the average person. Lucky for you, the professionals at Hopper Heating and Air are breaking down the system ratings to provide more education as you head into the purchasing process:
Annualized Fuel Utilization Efficiency (AFUE): This efficiency rating is a ratio that compares how much of the fuel you use in your furnace to the amount turned into useable heat. The higher the percentage of heat used, the better the system rating.
If your system has an AFUE rating of 85, that means the system turns 85 percent of the fuel used into useable heat. Systems that are highly efficient have an AFUE of 90 or higher. Lennox has residential furnaces with ratings up to 98.7—the highest in the industry.
Seasonal Energy Efficiency Ratio (SEER): The SEER rating is used to measure both heat pumps and air conditioners. Much like AFUE, this ratio looks at how much of the fuel used to power an HVAC system is converted to cooling output. The higher your unit’s SEER, the more efficiently it runs.
Minimum SEER ratings change between regions. High efficiency models are generally more expensive, but they provide more energy savings. Lennox makes air conditioners with SEER ratings up to 26—another industry leading rating.
Heating Seasonal Performance Factor (HSPF): Looking into heat pumps? This is the heating efficiency rating you need to know. A higher rating indicates a more efficient heat pump. If you want to find a solution that’s ENERGY STAR® efficient, that requires a rating above an 8.2—as well as a SEER rating above 12.
Minimum Efficiency Reporting Value (MERV): Air filters have holes that allow air and particles to move within your indoor space. MERV takes a look at the size of the holes. The higher the rating, the smaller the holes in the filter—and a decrease in the number of particles that get into your home. If you’re looking for a more efficient filter, find one with a MERV rating of 10 or higher.
Air filters are key to keeping the air in your home clean and comfortable. Make sure to find the rating that works with your home, with your system and change the filter on a consistent basis.
These ratings will be important as you search for a solution that meets your needs.
