Which maintenance task can help prevent energy loss in heat pumps?

Regularly cleaning evaporator and condenser coils is essential for maintaining the efficiency of heat pumps. Over time, dust, dirt, and debris can accumulate on these coils, which can significantly hinder their ability to transfer heat. This buildup leads to higher energy consumption as the system has to work harder to maintain the desired temperature. By ensuring that these coils are clean, heat pumps can operate efficiently, resulting in reduced energy loss and lower utility bills. Additionally, a well-maintained system tends to have a longer lifespan, which contributes to overall cost savings.

The other options involve neglecting maintenance or creating conditions that could contribute to energy loss, making them less desirable practices for maintaining efficiency in heating and cooling systems.
