Impact of Hard Water on Your Air Conditioner

Understanding The Impact Of Hard Water On Your AC

Hard water is water with a lot of minerals in it, such as calcium and magnesium. It’s not dangerous to drink, but it can cause problems with your appliances and plumbing.

Arizona has some of the hardest water in the country because our water comes from mineral-rich rivers and groundwater. The minerals get into the water as it flows through the ground and over rocks.

So, what does hard water do to your AC, and how do you protect your AC from hard water damage?

How Hard Water Affects Your Air Conditioner

Hard water, with its high mineral content, can adversely affect your air conditioner over time.

The minerals in hard water, such as calcium and magnesium, can accumulate on the evaporator coils as the air conditioner operates. These mineral deposits, often in the form of scale, diminish the coils’ efficiency in absorbing heat and moisture from the air, resulting in reduced cooling capacity and increased energy consumption. As the air conditioner works harder to reach the desired temperature, your energy bills may rise.

Hard water can also impact the condensate line, which is responsible for draining the water produced during the cooling process. Minerals in the condensate can accumulate within the line, potentially causing clogs.

A clogged condensate line can lead to water backing up into the unit or drain pan, causing leaks and potential water damage. It may also create a damp environment conducive to mold and mildew growth, affecting indoor air quality.

How To Minimize The Impact Of Hard Water On Your HVAC

To mitigate the negative effects of hard water on your air conditioner, consider:

  • Regular maintenance: Schedule routine AC maintenance. Technicians will clean the coils, check the condensate line, change air filters, and ensure the system operates efficiently.
  • Water softener: Install a water softener to reduce the mineral content in the water supplied to your air conditioning system. This can help minimize scale buildup on the evaporator coils and condensate line.
  • Condensate line cleaning: Periodically clean and clear the condensate line to prevent clogs and ensure proper drainage.

By addressing the impact of hard water on your air conditioner’s evaporator coils and condensate line, you can maintain the efficiency and performance of your cooling system while extending its life span.
