When it’s time for you to shop for a new home comfort system, you have to consider a lot of factors. Is it the appropriate size for your home? Will it provide the efficiencies you are looking for? Is the price point one you’re comfortable with? Will the unit be quiet enough for your house? How will it impact the air quality? It can be overwhelming. On top of all the questions you have, some HVAC knowledge seems just out of reach. The acronyms and shorthand that industry professionals already know can create questions for the average homeowner. Lucky for you, the experts at Jett's Heating & Air Inc. 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 links 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 makes 85 percent of the fuel used into useable heat. Systems that are highly efficient have an AFUE of 90 or higher. Lennox offers 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 an HVAC system is converted to cooling output. A more efficient system will have a higher SEER rating.
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): Do you own a heat pump or plan to shop for one? 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, 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 circulate within your indoor space. MERV measures 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 seeking a more efficient filter, find one with a MERV rating of 10 or higher.
Air filters are essential 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.
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.
