How Dust and Dirt Affect Your Air Conditioning System

Dust and dirt are so common it may seem like they shouldn’t have a big impact on your air conditioning system; unfortunately, nothing could be further from the truth. Just as getting sand in your smart phone can cause you endless problems, dirt and dust can have the same effect on your whole home AC. The problems may not be apparent at first, but if dust and dirt are left to accumulate on your system, you will start to see the effects, and they won’t be positive ones.

Reduced energy efficiency

You may be wondering how a little dust and dirt can reduce energy efficiency. There are a couple of ways this can happen. The first is how even a thin layer – less than an eighth of an inch – can affect how your coils and components work. Why does dirt and dust have such a deleterious effect? On your coils, even the thinnest layer can act as insulation, which will inhibit the heat release/cooling process. For individual components, dirt and dust help gum up operation, reducing how well a certain component will work.


Another way your energy efficiency can be affected is by having very dusty and dirty air ducts. If the dust and dirt in your system are allowed to develop into a layer, this layer can restrict air flow, which will affect how your system works. Dirty ducts can also significantly decrease your home’s indoor air quality.

Problems with Your Air Filter

The air filter in your air conditioning system isn’t made to work forever without being changed. In fact, it’s important to change your air filter every 3 months to ensure that it doesn’t become clogged. A clogged air filter can bring your Ac system to a stand-still, so it’s important to regularly change it.

With annual maintenance, you can avoid a lot of the problems caused by dust and dirt in your air conditioning system. Has it been a while since your system in New Hope, PA has been maintained? Then give the experts at Carney Plumbing Heating & Cooling a call today.
