A rusty HVAC will take longer to heat or cool your home and thus will result in high electricity bills. Moreover, if the rust is not removed timely it will spread and deteriorate the other AC components as well and all of this will lead to costly repair or even premature failure.
In this blog post, we will outline the top causes of rust on air conditioners and will also list some ways that will help you prevent your air conditioning unit from rusting.
Top Causes Of Rust On An Air Conditioning Unit
Rust forms on anything when the metal such as iron or steel are exposed to water and oxygen for a certain amount of time. Once the rust starts to form it quickly spreads and causes damage to the metal surface.
Some AC components that are likely to be affected by rust are its ductwork, air filters, drain pan, fan blades, refrigerant lines and compressors.
Here are some of the top causes that lead to rust on an AC:
Moisture is the biggest culprit of rust on air conditioners, which mostly comes from the rain, humid air and condensation.
The outdoor unit of your air conditioner deals with moisture on a daily basis. For example, when the HVAC system draws warm air from your home to be cooled the moisture from the air condenses on the evaporator coils and then drips on the drain pan.
This form of moisture is part of the daily functioning of your AC and is not harmful, however, the problem develops when an excessive amount of moisture stays in contact with your AC components for a longer period of time. This happens when the drain pan of your air conditioner is clogged.
If you live in a coastal area salty humid air will also lead to rusty conditions for your air conditioner outdoor unit. Other factors like your outdoor unit being surrounded by plants and rain falling directly on your outdoor unit will also accelerate the rusting process.
Air Conditioner Aging
Air conditioners typically have a lifespan of about 10-15 years and rusting is a normal part of aging. When your air conditioner unit is near its end of life, it will degrade due to regular wear and tear.
The aging signs such as rusting, high energy bills, weird AC noises and decreased airflow will start to appear once your air conditioner unit has reached its end of life.
