When you’re searching for a new HVAC system, there are a lot of factors to think about. Is it the appropriate size for your home? Is it energy efficient? How does the system work with your finances? Will the unit be quiet enough for your house? How will it impact the air quality? It can be overwhelming. On top of all the inquiries you have, some HVAC knowledge seems just out of reach. The acronyms and shorthand that industry professionals use can raise more questions for the average individual. Luckily, the experts at Oak Grove Heating & Air Conditioning 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 associates 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. If you are looking for a highly efficient system, you’ll want one that has an AFUE of 90 or higher. Lennox offers 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. Similar to AFUE, this ratio measures 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 carries air conditioners with SEER ratings up to 26—another industry leading rating.
Heating Seasonal Performance Factor (HSPF): Have a heat pump? This will be what you’ll want to take a look at as far as heating efficiency. The higher your heat pump is rated, the more efficient it is. If you want a model 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 circulate 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 the fewer debris particles that enter into your home. If you’re seeking a more efficient filter, find one with a MERV rating of 10 or higher.
Air filters are essential to the quality of air in your home. Make sure to find the rating that works with your home, with your system and change the filter on a consistent basis.
