If you are looking for a new heating and cooling system, you have a lot of different features to think about. Is it the correct 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? Will it be beneficial for your indoor air quality? You have a lot to think about when considering the best solution. 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 create questions for the average person. Lucky for you, the team at Hix Air Conditioning Service, Inc. are breaking down the system ratings you need to know before making a purchase:
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. 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): This rating is used in both air conditioners and heat pumps. Similar to AFUE, this ratio compares 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 carries air conditioners with SEER ratings up to 26—another industry leading rating.
Heating Seasonal Performance Factor (HSPF): Do you own a heat pump or plan to shop for one? 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 are in the market for a heat pump that’s ENERGY STAR® efficient, then look for a model with a rating above an 8.2—as well as a SEER rating above 12.
Minimum Efficiency Reporting Value (MERV): Air filters have holes that permit air and particles to flow around the house. 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 make their way into your home. If you’re seeking a more efficient filter, find one with a MERV rating of 10 or higher.
Air filters are key 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 frequently.
Finding an HVAC system that fits with your home, your energy efficiency needs and your desired comfort starts with understanding ratings.
