If you are looking for a new heating and cooling system, you have a lot of different features to think about. Is it the appropriate size for your home? Will it be energy efficient? Is the price point one you’re comfortable with? Will the unit be quiet enough for your space? How will it impact the air quality? You have a lot to think about when considering the best solution. 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 raise more questions for the average person. Fortunately, the professionals at Colvin's Heating and Cooling 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 associates 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 converts 85 percent of the fuel used into useable heat. A system with an AFUE of 90 or higher is considered high efficiency. Lennox has residential furnaces with ratings up to 98.7—the highest in the industry.
Seasonal Energy Efficiency Ratio (SEER): The SEER rating is used to measure both heat pumps and air conditioners. A lot like AFUE, this ratio compares how much of the fuel used to power a home comfort 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 is the heating efficiency rating you need to know. A higher rating indicates a more efficient heat pump. If you want to find a solution that’s ENERGY STAR® efficient, that requires 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 measures the size of the holes. The higher the rating, the smaller the holes in the filter—and the fewer debris particles that get into your home. If you’re wanting 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.
These ratings will be important as you search for a solution that meets your needs.
