Let’s look in more detail at some problems that develop as a result of dirt, dust, and other debris.
- Frozen evaporator coil. Frozen coils are one of the most common issues affecting air conditioners in the summer months. There are several reasons why it can happen in your home, including low refrigerant. But one of the most common reasons is related to a clogged air filter as a result of excessive dirt. When debris builds up on your air filter, it not only no longer performs its function, but also blocks the flow of cool air, which can then buildup inside your air handler.
- Dirty condenser coils. Your condenser coils are subject to increased levels of debris because of their outdoor location. However, they need to be kept clean in order to function properly. They play an important role in dissipating the thermal energy drawn from your indoor air into the outside air. But they simply will not be effective if they are caked with debris.
- Blower motor fault. Dirt and dust are bad for motors. They create friction and reduce the effectiveness of moving parts that often require lubrication to operate. If dirt and debris get inside your blower motor components, then it could shut down, which means that your system cannot operate.
