Efficiency Questions

The U.S. government requires an efficiency rating of all air conditioning and heating equipment. The rating reflects the percentage of energy used efficiently, with a high rating indicating high-efficiency. The next two topics address this issue in greater detail.

There are special names for the efficiency ratings of various types of equipment. Air conditioning equipment is rated by the Seasonal Energy Efficiency Rating, or SEER. The higher the SEER rating, the more efficient the unit. An easy way to look at it is to think of SEER the way you would think of miles per gallon on a vehicle. 

Gas furnaces are rated according to their Annual Fuel Utilization Efficiency, or AFUE. The higher the AFUE rating, the more efficient the unit. You may see an 80% furnace which exhausts through metal pipe. You may also see 92% or higher which vents in PVC due to lower exhaust temperatures.

A good way to look at the efficiency of these numbers is, for example, a 95% furnace. This means, .95 cents to every dollar you spend on gas (or heat) stays in your home and the other .05 cents is exhausted outside.

Preferably auto. That way, the fan operates only when the temperature requires it. This is the most used and the most efficient setting. However, there are advantages to using the “on” setting. Air is constantly filtered through the unit’s air filter, and the constantly circulating air results in an even temperature throughout the house.
