What is a condensate pump? In HVAC or refrigeration process, the water that condensate need to be channeled out from the building to proper drainage outside the building. The condensation process usually occurred when the air passes though the cold evaporator coil during the cooling process.
As a result, the moisture that accumulate on the coil then drip down into the drain pan that is placed underneath the coils.
Systems that are able to use the gravitational force to flow the water that accumulate on the drain pan does not require the use of the pump. However, there are many instances when the air conditioning systems require to use of this pump to get the water out to prevent the water from dripping into the space.
The condensate pump that is used in residential system is usually low power(approximately 60W) and simple in function. However, regular inspection of this unit is critical as you do not want to have to come back to your house with water dripping all over your carpet, furnitures or electrical goods.
It is always a good idea to find out whether your air conditioner is using the pump in its operation. Generally, the condensate pump has the following specifications and functions that you should know:

Take note of the following before buying the pump for replacement.
In temperate countries, it is critical that the condensate water that goes out through the piping is totally drain out especially during winter. This is important because the water that is not drained out will freeze and may crack the piping or cause improper functioning of the system.
