When you’re searching for a new HVAC system, you have a lot of different features to think about. Is it the correct size for your home? Is it energy efficient? Is the price point one you’re comfortable with? Will the unit be quiet enough for your home? Will it be beneficial for your indoor air quality? That’s a lot to think about. 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 individual. Luckily, the experts at Cool Air Solutions 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 links 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. 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. Much like AFUE, this ratio measures how much of the fuel used to power a home comfort system is converted to cooling output. The higher the SEER rating, the more efficient your system is operating.
Minimum SEER ratings vary 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. 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 let air and particles to move through your home. 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 enter 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 essential to indoor air quality. Make sure to find the rating that works with your home, with your system and change the filter on a consistent basis.
