When it’s time for you to shop for a new home comfort system, you have a lot of different features to think about. Is it the right size for your home? Will it be energy efficient? How does the system work with your finances? Will the HVAC system be quiet enough for your space? What kind of air quality can you expect? 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 use can be confusing for the average person. Fortunately, the experts at American HVAC Inc 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 associates how much of the fuel you use in your furnace to the amount turned into useable heat. A better system will have a higher percentage of heat used.
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 carries 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 heating and cooling system is converted to cooling output. The higher your unit’s SEER, the more efficiently it runs.
Minimum SEER ratings vary between regions. High efficiency models are generally more expensive, but they provide more energy savings. Lennox offers 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 to find a solution 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 move within your indoor space. MERV measures 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 regularly.
Keeping these ratings in mind as you begin looking for a new system will help ensure you find one that meets your needs and will work with your home.
