Efficient Heating and Cooling in Austin, Texas: R U Confused?

When it comes to purchasing a new HVAC, it can be difficult to understand all the ratings and what they mean. A good company like http://aircoaustin.com/aboutus/ will explain these ratings to you, but it doesn't hurt to gain a little knowledge so you can be sure that you are getting an efficient unit. This article has a list of the most common acronyms you will encounter and what they stand for.

 

EER, or the Energy Efficiency Ratio, is calculated by comparing how much cool air is generated for a dollar of electricity. These calculations are based on the hottest day.

 

SEER, or the Seasonal Energy Efficiency Ratio, uses the same basic calculations as the EER, but it measures the efficiency for a whole season, not just the hottest day. A SEER rating ranges between thirteen and seventeen, though seventeen is recognized as being the most efficient.

 

AFUE, or the Annual Fuel Utilization Efficiency, determines how much heat is generated for a dollar of fuel in order to achieve its rating. An efficient furnace is rated at seventy eight percent or higher, but if you want it to be highly efficient, look for a rating of ninety percent or more.

 

HSPF, or the Heating Seasonal Performance Factor, determines how much heat is generated for a unit of electrical energy. Ratings range from about seven to ten, though truly efficient units should be rated at seven and a half or higher.

 

If you are still confused, don't worry. An Energy Star designation means that the system you are considering for your heating and cooling in Austin meets or exceeds industry standards for efficiency, though knowing the rating system will help you understand just how compliant they are.

 

When choosing a system, make sure that your technician assesses your home so you can be sure that the HVAC is sized properly. An improperly sized unit, big or small, will greatly reduce the efficiency savings that you are likely hoping to see.
