Condensate Pump Operation

An air conditioner condensate pump is a device that pumps the water produced by an air conditioning system's condenser coil out of the unit and away from the building. Air conditioning systems generate condensate water when they cool warm, humid air. This water is usually collected in a tray or pan underneath the evaporator coil and drained away. However, if the air conditioner is located in a basement or other low-lying area, it may be necessary to use a condensate pump to lift the water to a higher elevation so that it can be properly drained.

The condensate pump is typically installed in the air conditioning unit's drain pan or nearby, and it is connected to a discharge pipe that leads to the outside of the building or to a drain. The pump is activated when the water level in the drain pan reaches a certain height, and it pumps the water out of the unit and into the discharge pipe. Some condensate pumps also have a safety switch that shuts off the air conditioning system if the pump fails or if the water level in the drain pan becomes too high.

Condensate pumps are commonly used in commercial HVAC systems, but they can also be useful in residential settings where the air conditioner is located in a basement or other low area. They are typically small, quiet, and easy to install, and they can help prevent water damage and mold growth that can result from standing water in the air conditioning unit's drain pan.

The ESCO Institute "Did you Know?" podcast provides HVACR professionals access to reliable, up-to-date, and relevant information, directly from trusted sources. The world of HVACR has been changing at an exponential rate over the last few years; new SEER ratings, flammable refrigerants, and an array of technological advances. Keeping up with all the changes in regulation, manufacturing, refrigerants and how to properly prepare students and technicians has became daunting. Many of our guests are speakers and exhibitors at the HVAC EXCELLENCE National HVACR Education Conference and represent every sector of the HVACR industry. Thanks for joining in!
