How Dust Can Ruin Your Air Conditioner

Keeping your house at a cool temperature during the summer is obviously important, so you should do everything you can to keep your air conditioner in good working order. One way that you can keep your air conditioner in good health is be reducing the amount of dust that your air conditioner sucks in. Too much dust in your air conditioner can greatly reduce the airflow, and can keep the air from being cold.

Dust Can Prevent Your Air Conditioner From Working Properly

It may sound counter-intuitive, but you do not want your air conditioner to get too cold. Inside of your air conditioner is a part called a condenser coil. This is coil acts as a heat sink which pulls heat out of your home's air. If your air conditioner's condenser coil is coated with a layer of dust, then it will prevent this heat transfer for happening, which will greatly reduce your air conditioner's capability to cool your home. 

Dust Can Cause Your Air Conditioner to Freeze

Inside of your air conditioner's condenser coil is a series of thin fins, which provide a larger surface area for heat transfer to happen. When these fins get dirty with dust and debris, they soak up a lot of condensation-caused water, which then freezes. It is actually a bad thing for ice to form in your air conditioning unit, because it can reduce airflow and prevent heat in your air from being taken out. 

If your air conditioner's fins get dirty, then it is important to have a professional air conditioner repairman—such as H R Stewart Inc.—repair your unit for you. You will likely bend your fins if you try to clean it yourself, which can lead to even further freezing and worse ice problems. Bent fins in an air conditioner's condenser coil are extremely hard to repair, and can often mean that you will have to replace your air conditioner all together.

How to Prevent These Things from Happening

The best way to keep dust from ruining your air conditioning system is to keep your home as dust-free as possible. Be sure to vacuum at least once a week, and dust all of your surfaces with a duster which clings to the dust and doesn't simply scatter it back into the air. Also, it is important to change your home's air filter regularly as well, because no matter how clean you keep your home, there will always be dust in your air.
