If you are looking for a new heating and cooling system, you have to consider a lot of factors. Is it the correct size for your home? Is it energy efficient? Is the price point one you’re comfortable with? Will the system be quiet enough for your home? Will it be beneficial for your indoor 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 be confusing for the average homeowner. Lucky for you, the team at Titan Heating & Air Conditioning 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 converts 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): Both heat pumps and air conditioners use this rating. Similar to AFUE, this ratio compares how much of the fuel used to power a heating and cooling system is converted to cooling output. A more efficient system will have a higher SEER rating.
Minimum SEER ratings change 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 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 permit air and particles to move around the house. MERV assesses 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 seeking a more efficient filter, find one with a MERV rating of 10 or higher.
Air filters are critical 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 on a consistent basis.
