Your Heating, Ventilation, and Air Conditioning (HVAC) system can cause extensive water damage if it isn’t preserved properly. Frequent causes of HVAC water harm include a clogged drain, suspended evaporator coils, and pipes that are not connected correctly. 

So, it’s important to care for your HVAC system at least once every year. That helps to prolong the life span of your unit and prevent additional heating or cooling expenses. The fantastic news is that HVAC maintenance jobs are rather easy to do and do not involve hiring a professional most of the time.

How to Prevent HVAC Water Damage

Change the HVAC filter regularly

  • Shifting the filter helps prevent the device from overworking, which may cause freezing and then defrosting on the evaporator coils, resulting in HVAC water damage. Some air filters have to be changed twice per year, others once a month, depending on their type and how frequently you use the HVAC system.
  • Check the instructions guide to know what type of filter you want.
  • If the filters are within the furnace or air handler, hire a contractor to modify the filters.

Clean the condenser

  • The condenser is the outside portion of your air conditioner or heat pump. It requires appropriate airflow to work effectively.
  • Any dirt or other debris that collects on the condenser ought to be removed once annually (preferably at the beginning of spring).
  • Also, make certain that you keep plants from the condenser and eliminate any cover from it to ensure proper airflow.
  • Leave at least two feet of space between the device and the shrubs or trees in your yard.

Keep the condensation drain line

  • When your AC device is operating, check the condensation line opening to make sure you see water flowing into the drain. The quantity of water which flows depends on the humidity level in the home. Locate the drainage hole around the base of the cabinet (underneath the evaporator fins). Use a paper clip or wire to poke through the hole and clear it, thereby ensuring the AC drainage is kept clean.
  • One or two times a year, flush your drain with an algaecide to prevent algae or mold from forming. Use a commercial alternative or regular bleach.
  • Be sure to correctly connect and install the main drain line and crisis drain line.
  • Check that the pipe is oriented properly, as it might be knocked out of alignment.

How to unclog the drain line

  • Sometimes, the drain line gets clogged with algae, grime, mineral deposits, and even mold or mildew, causing water to flow into your home.
  • Attach a wet/dry vacuum into the drain line (removing the paper filter) and suck out the clog.
  • Consider installing an overflow shut off apparatus on the drain line to automatically switch off the A/C unit when the drain line backs up.

Put in a condensation pump

  • Another tip about how best to avoid HVAC water damage is to put in a condensation pump.
  • That helps excess water flow to the suitable disposal drain.
  • Also, install a security float switch to automatically shut down the power to your AC unit whenever moisture builds up, and there’s a risk of water overflow.

Keep the overflow drain pan

  • The drain pan collects any water that has overflowed because of a clogged drain line.
  • As time passes, drain pans made from metal or plastic may get damaged, resulting in leaks and water damage.
  • If you notice leaks close to the drain pan, carefully inspect it for damage using a flashlight.
  • Contemplate patching up small cracks or holes using adhesive glue or replacing the pan entirely.
  • Regularly clean the skillet. Rinse the pan and then clean it using a bleach-water mixture to clear out any mold or mold growth.

Have your HVAC system inspected professionally

  • HVAC inspection and maintenance can be difficult for homeowners, therefore selecting a professional is a fantastic idea.
  • Apart from the jobs already mentioned, they can inspect and fix issues associated with HVAC components.
