What is one effect of using a dirty evaporator coil?

Using a dirty evaporator coil significantly impacts the overall efficiency and functionality of an HVAC system. When the coil is dirty, it creates a barrier that impedes the heat exchange process, which leads to reduced cooling efficiency. This inefficiency requires the system to operate longer and work harder to achieve the desired temperature, resulting in increased strain on the entire HVAC system. The overworking of components can lead to premature wear and tear, potential breakdowns, and higher energy costs due to increased electricity consumption.

In contrast, improved cooling efficiency, faster cooling of air, and enhanced air circulation would typically occur when the coil is clean and functioning optimally. A dirty coil inhibits these processes, highlighting why recognizing and addressing cleanliness in evaporator coils is essential for maintaining an HVAC system's effectiveness and longevity.
