What Effect Can Excessive Dirt and Dust Have on an Air Conditioning System?

Every air conditioning system is going to attract dust and dirt. However, when the levels of dust and dirt become excessive, different components can be negatively affected and cause potential operating problems for you air conditioning system. What kind of problems can arise?

Here Are Examples of How Excessive Dirt and Dust Can Impact Your Air Conditioning System


There are two sets of coils in your air conditioning system: the condenser coils and the evaporator coils. These coils play an important role in the heat release and cooling processes within your air conditioning system, and if anything obstructs this process, it can affect how your whole system operates. If dust and dirt are allowed to build into a layer that sits on your coils, this layers acts as insulation, which can interfere substantially with heat release and cooling.

Air Filter

Your air conditioner’s air filter is designed to capture large particles of dust and dirt to prevent them from entering the air stream of your system. However, this filter can become clogged with regular use, and if not changed regularly, (every 1-3 months), this filter can become so clogged that it may constrict the air flow in your system.


Sometimes with ductwork, the old saying “out of sight, out of mind,” can be all too true. It can be easy to forget about your ductwork because you can’t see it, but when too much dust and dirt is in your vents, a number of problems can develop, including poor indoor air quality and stress on your system. While it isn’t necessary to clean your ductwork annually – recommendations are for every 3-5 years – it is important to have them inspected and cleaned when necessary.

One of the best ways to manage the dust and dirt in your system is with bi-annual maintenance. During a routine maintenance appointment, your entire system is thoroughly inspected, and your coils are cleaned and air filters changed.
