A condensate pump is a small but vital part of your HVAC system. It removes condensation from your air conditioner or furnace and pumps it outside. If your condensate pump becomes clogged, it can cause a number of problems, including water damage to your home.
Key Facts
- Turn off the power: Before attempting any maintenance on your HVAC system, make sure to shut off power to the unit at the breaker panel.
- Locate the condensate pump: Typically, condensate pumps are located directly on or beside the furnace. You should notice a small plastic box connected to a white PVC pipe on the side of your furnace.
- Disconnect the pump: Unplug the pump and disconnect it from the PVC pipe. Then, remove it from the wall.
- Empty the pump: Use a flathead screwdriver to remove the top of the pump. Empty all the water from inside the pump.
- Rinse the pump: Using warm, clean water, rinse the pump to remove any buildup of gunk, dirt, and debris from the inside of the pump. Be sure to rinse the drain openings where the drain lines connect as well.
- Remove stubborn dirt and debris: Use a bottlebrush or a similar tool to remove any stubborn dirt and debris still present in the reservoir or drain openings. For small, hard-to-reach areas of the pump, using compressed air can help remove any additional debris.
- Consider using algae tablets: If you notice a large amount of algae growth in your AC condensate pump, consider purchasing algae tablets from your local home improvement store. Algae tablets offer a great solution to keep your condensate pump clean and clear for extended periods of time.
