If you are looking for a new heating and cooling system, there are a lot of factors to think about. Is it the correct size for your home? Will it be energy efficient? Will it work with your budget? Will the HVAC system be quiet enough for your home? How will it impact the air quality? It can be overwhelming. On top of all the factors you want to learn more about, some HVAC knowledge seems just out of reach. The acronyms and shorthand that industry professionals already know can raise more questions for the average homeowner. Lucky for you, the professionals at Central Aire Heating & A/C Inc are breaking down the system ratings to give you a better understanding as you begin shopping:
Annualized Fuel Utilization Efficiency (AFUE): This efficiency rating is a ratio that links 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. A system with an AFUE of 90 or higher is considered high efficiency. 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. A lot like AFUE, this ratio looks at how much of the fuel used to power a home comfort system is converted to cooling output. A more efficient system will have a higher SEER rating.
Minimum SEER ratings vary 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 rating to keep in mind. You’ll want to look for heat pumps with a higher rating if efficiency is your goal. If you are in the market for a heat pump that’s ENERGY STAR® efficient, you’ll need 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 assesses the size of the holes. The higher the rating, the smaller the holes in the filter—and the fewer debris particles that enter 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 frequently.
