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? Will it be 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? You have a lot to think about when considering the best solution. 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 be confusing for the average individual. Fortunately, the experts at Paso Robles Heating and Air 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 compares how much of the fuel you use in your furnace to the amount turned into useable heat. You’ll find that the better systems 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. A system with an AFUE of 90 or higher is considered high efficiency. 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. Much like AFUE, this ratio looks at how much of the fuel used to power a heating and cooling system is converted to cooling output. The higher the SEER rating, the more efficient your system is operating.
Minimum SEER ratings differ between regions. A high efficiency model that provides more energy savings in the long run will generally be a little more expensive. 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. You’ll want to look for heat pumps with a higher rating if efficiency is your goal. 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 flow 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 fewer particles that enter into your home. If you’re wanting a more efficient filter, find one with a MERV rating of 10 or higher.
Air filters are critical 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.
These ratings will be important as you search for a solution that meets your needs.
