What is a Condensate Pump?

The condensate pump is the part of your HVAC system that is responsible for pumping the condensate (water) that is produced from refrigeration and heating. Your air conditioner works by absorbing the warmth and humidity from your home. Then, it separates the moisture, causing water droplets to drip into a drip pan. As water levels rise in the reservoir, the condensate pump pushes the water out of your home through the condensate line.

What Happens If a Condensate Pump Fails?

The biggest indicator of an issue with your condensate pump is that your air conditioner won’t turn on. The AC shuts off to prevent the pump’s water reservoir from overflowing. If your condensate pump is malfunctioning, it may need to be repaired, cleaned or replaced.

How to Check If Your Condensate Pump is Working

Step 1. Turn off your air conditioner. For your safety, shut the power off at the breaker panel too.

Step 2. Locate the pump. Next to your furnace, you will see a rectangular box that serves as the pump reservoir. Remove the top. The receptacle will contain water.

Step 3. Check the microswitch. If water is overflowing out of the reservoir, it is likely that the microswitch for the main float has failed or the pump motor has failed. Gently tap the main float’s microswitch to see if the pump starts running. Often when microswitches fail, they can be fixed this way. If the float is cracked or damaged, it will need to be replaced.

Step 4. Check the safety switch. If the pump has a safety switch and your air conditioning or furnace won’t turn on, empty the water from the pump’s reservoir. This will buy you a little time to replace the pump.

Step 5. Check for a clogged drain line. Locate the drain hose and place a cup at the dispensing end of it. Pour water into the hole at the top of the pump. If water drains into the cup at the end of the hose, the line is not clogged. If the condensate pump is not pushing water through, the impeller on the pump is likely dirty or clogged. To remedy this, flush it with a cup of vinegar, peroxide, or bleach. You should clean the pump occasionally to avoid accumulation of debris and algae growth in this one-way valve.

Step 6. Purchase a new pump. If none of the above has worked, you will need to replace your condensate pump. You can purchase a new one at any home improvement store.

Step 7. Schedule regular AC maintenance. It is highly recommended to schedule regular AC maintenance to prevent additional AC issues from happening.
