What maintenance step helps prevent HVAC system overloading?

Regular cleaning of condenser and evaporator coils is crucial for preventing HVAC system overloading because these components are essential for the system’s ability to transfer heat efficiently. When coils become dirty or clogged with debris, it hinders the heat exchange process. This inefficiency can cause the system to work harder than necessary to maintain the desired indoor temperature, leading to increased energy consumption and potential overheating of the unit. Over time, this can result in wear and tear on components, reduced lifespan of the system, and higher utility bills. Ensuring that these coils are clean allows the HVAC system to operate smoothly, maintaining both performance and energy efficiency.
