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 right size for your home? Will it provide the efficiencies you are looking for? Is the price point one you’re comfortable with? Will the system be quiet enough for your space? How will it impact the air quality? That’s a lot to think about. 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 raise more questions for the average homeowner. Luckily, the experts at True Temp Heating & Air Inc 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 makes 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): This rating is used in both air conditioners and heat pumps. Similar to AFUE, this ratio compares how much of the fuel used to power an HVAC system is converted to cooling output. The higher the SEER rating, the more efficient your system is operating.
Minimum SEER ratings differ between regions. Choosing a high efficiency model may be more expensive on the front end, but you’ll see greater energy savings throughout the years. Lennox makes 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. A higher rating indicates a more efficient heat pump. If you want a model 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 around the house. MERV assesses 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 essential 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 regularly.
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.
