Which of the following is a method to increase residential air conditioning efficiency?

Installing heat pumps is an effective method to increase residential air conditioning efficiency. Heat pumps are versatile systems that can both heat and cool a home. They work by transferring heat rather than generating it directly, which allows them to provide significant energy savings compared to traditional heating and cooling systems. During warm weather, heat pumps remove heat from the indoor air and transfer it outside, while in cooler months, they can reverse the process to provide heating. This ability to efficiently move heat means that heat pumps typically operate with a higher coefficient of performance (COP), leading to lower energy consumption and reduced utility costs.

Additionally, heat pumps generally use less electricity than conventional air conditioning systems for the same level of comfort, making them a more sustainable choice for homeowners looking to reduce their environmental impact while maintaining a comfortable living environment. This efficiency can be further enhanced with proper installation and regular maintenance, ensuring ideal performance throughout their operational lifespan.
