Good insulation will help to keep your home cool and comfortable by reducing the workload placed on your air conditioning system.
2. The Size of Your Home
The size of your home is another factor that affects air conditioning efficiency. A small air conditioning unit may not be sufficient to provide enough cool air for a large home. A bigger unit may be necessary if it’s a larger home. However, an oversized unit will result in energy wastage, which will increase your electric bill.
3. The Temperature and Humidity of the Region
The temperature and humidity of the region also play a significant role in air conditioning efficiency. Regions with high levels of humidity and temperature will require a more efficient air conditioning unit to provide the necessary cooling. For instance, a standard 13 SEER unit may suffice for regions with mild temperatures, while regions with high humidity and temperature may require a highly efficient unit with a minimum rating of 16 SEER.
Types of Air Conditioning Efficiency Ratings
There are several types of air conditioning efficiency ratings, which are considered the industry-standard for measuring the unit’s efficiency. They include the following.
1. Seasonal Energy Efficiency Ratio (SEER)
The Seasonal Energy Efficiency Ratio (SEER) rating is the most commonly used measure of air conditioning efficiency. It is a measure of how efficiently the unit will cool your home throughout the year, taking into account the seasonal changes in temperature and humidity. The SEER rating ranges from 13 to 26, with the higher rating indicating a more energy-efficient unit.
2. Energy Efficiency Ratio (EER)
EER rating is another way to measure air conditioning efficiency. It measures the unit’s efficiency based on a specific temperature rating (95°F) and is used as a standard for central air conditioning units. The higher the rating, the more efficient the unit.
3. Annual Fuel Utilization Efficiency (AFUE)
AFUE measures the efficiency of heating and cooling components in your home. This rating is often used in forced-air heating systems and is the level of efficiency for gas or oil-fired furnaces. The higher the rating, the more efficient the unit.
4. Heating Seasonal Performance Factor (HSPF)
The Heating Seasonal Performance Factor (HSPF) rating is used to measure the efficiency of heat pumps. In other words, this rating measures heating efficiency. The higher the rating, the more efficiently the unit will heat your home.
