Simple Steps You Can Take To Prevent an HVAC Water Damage

If your heating, ventilation, and air conditioning (HVAC) system is not maintained correctly, it can cause severe water damage, leaving you with a huge mess to clean up. Clogged drains, frozen evaporator coils, and pipes that are not connected correctly are common causes of HVAC water damage. You must care for your HVAC system at least once a year. Regular maintenance helps to prolong the life of your unit and prevent additional heating or cooling expenses. Most HVAC maintenance tasks are pretty easy to do yourself, so there is usually no need to hire a professional most of the time. 

Preventing HVAC Water Damage

Change your HVAC filter regularly.

• Changing the filter prevents the unit from overworking, which can cause freezing and then defrosting on the evaporator coils, leading to HVAC water damage.
• Change the filter at least once a month with high-efficiency particulate air (HEPA) filters. Some air filters only need to be changed twice a year or once a month, depending on their type and how often you use your HVAC system.
• Check your instruction manual first to know what type of filter you need and how often you need to change it.
• Hire a contractor to change the filters if the filters are inside the furnace or air handler.

Clean the condenser

• The condenser is the exterior portion of your air conditioner or heat pump. It requires proper airflow to work correctly.
• Once a year, at the beginning of spring, remove any dirt or other debris accumulating on the condenser.
•  Keep plants away from the condenser and remove any covers from it to ensure proper airflow.
• Leave at least two feet of space between the unit and the bushes or shrubs in your yard.

Maintain the condensation drain line

• When your AC unit runs, check the condensation line opening to make sure you see water flowing to the drain. The amount of water that flows depends on the humidity level in the house.
• Clean the AC drainage holes. Locate the drainage hole on the base of the cabinet (beneath the evaporator fins). Use a paper clip or wire to poke through the hole and clear it, thus ensuring the AC drainage is kept clear.
• Once or twice a year, flush out your drain line with an algaecide to prevent mold or algae from forming. Use a commercial solution or regular bleach.
• Make sure to properly connect and install the main drain line and emergency drain line.
• Check that the pipe is oriented correctly, as the weather might have knocked it out of alignment.

How to unclog the drain line

• Sometimes, the drain line gets clogged with algae, dirt, mineral deposits, and even mold or mildew, causing water to overflow into your home.
• Attach a wet/dry vacuum to the drain line (removing the paper filter first) and suck the clog out.
•  Install an overflow shut-off device on the drain line to automatically turn off the AC unit if the drain line backs up.

Install a condensation pump

• To avoid HVAC water damage, install a condensation pump in your unit. That helps excess water flow into the proper disposal drain.
• Additionally, install a safety float switch to automatically shut down the power to the AC unit whenever condensation builds up when there is a risk of water overflow.

Maintain the overflow drain pan

• Your unit's drain pan collects water that has overflowed due to a clogged drain line.
• Over time, the drain pan may get damaged, resulting in leaks and water damage. If you notice leaks near the drain pan, carefully inspect it for damage using a flashlight.
•  Patch small holes or cracks using epoxy glue or replacing the pan entirely.
•  Clean the drain pan regularly. Rinse the pan and clean it with a bleach-water mixture to clear out any dirt or mold growth.
