A furnace needs a condensate pump to effectively take away and remove excess water from them. These pumps replace the conventionally used hoses and transfer water to drainage pipes. Condensate pumps are more preferred since they do not rupture like hoses and ensure efficient water drainage.

Condensate pumps are also used to pump away excess water that flows through a furnace humidifier during the winter. As it is a mechanical item, a condensate pump can fail over time, although they're usually pretty reliable.Oct 28, 2007

What does a condensate pump do?

The condensate pump is a type of pump that takes in the water produced by the HVAC system while heating or cooling. The water can come from steam, refrigeration, or a condensing boiler furnace. The job of the pump is to remove the excess condensation produced.

Why is there condensation on the inside of my furnace?

This adds up to a lot of water vapor. In order for the furnace to work properly, that condensation needs to be drained out or else it would accumulate inside the heat exchanger, inducer and venting, impeding proper gas/combustion product flow.

Why is my condensate pump not pumping water out?

The reason this happens is a safety measure to prevent the pump’s water reservoir from overflowing and causing puddles all around your home. If your condensate pump is not pumping water out or not working as it should, follow these step by step directions. Step 1. Turn off your air conditioner.

Do you need a condensate drain on a gas furnace?

All condensate drains go into a trap. The condensate trap is absolutely mandatory for a high-efficiency gas furnace. Since the drain taps into the exhaust system, leaving it open to the air would allow for a potential exhaust/flue gas leak in the living space, which is a big no-no.

How often should furnace condensate pump run?

It is essential that the condensate pump system is regularly checked for correct operation. The frequency will depend on the environment in which the unit is operating but should be a minimum of once every 3 months.

Does condensate pump work with furnace?

But many older homes don't have a floor drain next to the furnace. So furnace installers mount a condensate pump right on the furnace and route the drain line to a far-off sink or floor drain. If that condenser pump fails, the water overflows the pump and spills onto the floor.

Can I unplug my condensate pump?

Q: Can you unplug a condensate pump? A: Yes, but only for maintenance. If a condensate pump has been installed on your system it's there for a reason and should be left on while your unit is running.

Where should furnace condensate drain?

The condensate drains out through a pipe, usually on the bottom of the furnace. Most high-efficiency furnaces also have a secondary drain line that comes out of the flue pipe. This secondary line is used to drain any residual moisture so it doesn't leak into your furnace.

Should condensate pump run all the time?

If a condensate pump runs all the time, it can burn out the motor, and may even cause water damage to your home.

Do heat pumps condensate in winter?

Heat Pumps Often Ice Up During Cold Weather This happens when the pump generates heat, the refrigerant turns to gas and then condenses when it meets the outdoor coil. In winter temperatures, this condensation will freeze. That's why the pump also has a defrosting function.

Why does my condensate pump keep filling up?

Over time, algae and debris can build up inside of the condensate pump, forming clogs throughout the device – especially on the valve. Cleaning the valve is relatively simple. All you have to do is remove the drain line from the valve, remove the valve, clean it, and reinstall it.

What is the small pump next to my furnace?

Condensate pumps are also used to pump away excess water that flows through a furnace humidifier during the winter. As it is a mechanical item, a condensate pump can fail over time, although they're usually pretty reliable.

What is condensation on a furnace?

Furnace condensation is typically a buildup of water around the unit's base. This can be caused by a few different phenomena but doesn't necessarily indicate a problem with the furnace. Advertisement.

What happens if a furnace hose is blocked?

If these hoses become blocked up, knotted or obstructed in any way, it could cause the natural flow of water to back up onto the furnace and produce the appearance of condensation.

What is an HVAC unit?

Heating, Ventilation and Air Conditioning. An HVAC unit is a furnace that also incorporates vents and a central air conditioner into your home. If the furnace connected to the HVAC system is producing condensation, the problem could just as easily be with one of the other pieces of equipment as with the furnace unit.

What is a frozen pipe in a furnace?

Frozen Pipes. A series of pipes used for various purposes is connected to your furnace. These pipes run throughout your house, and certain pipes even run outside. If the furnace is producing condensation during the winter, the problem could be that one of these pipes has frozen and is backing up all the way to the main furnace unit.

Can a furnace produce condensation?

Certain types of furnaces naturally produce condensation over time. This is not an issue. These furnaces often have a specialized drain used to collect the condensation that should prevent you from ever seeing it. If you notice your furnace is producing more condensation than normal, check to make sure nothing is obstructing the condensation drain and preventing it from emptying.

Why do furnaces use heat exchangers?

High efficiency (or 90%, or condensing) furnaces use a set of two heat exchangers to retrieve more heat from the combustion products than their mid-efficiency counterparts. Because of this, they generate flue gases much colder than those of a mid-efficiency or natural draft unit. That not only completely changes the way ...

How many drains does a furnace have?

Most furnaces will have at least two internal drains, typically one for the heat exchanger and one for the vent, usually at the inducer outlet or on the inducer housing. The secondary heat exchanger outlet is sealed inside a plastic part called the collector box, designed to collect the condensate and drain it.

Can you run a furnace drain in an area that freezes?

Avoid running the drain in an area where it could freeze. That includes running it under the natural fresh air inlet if there is one. Finally, note that furnace condensate is acidic, and some states/provinces/countries may require the condensate to be neutralized prior to draining. —Ben. Share this:

Do condensate drains go into traps?

All condensate drains go into a trap. The condensate trap is absolutely mandatory for a high-efficiency gas furnace. Since the drain taps into the exhaust system, leaving it open to the air would allow for a potential exhaust/flue gas leak in the living space, which is a big no-no.

How does a condensate pump work?

What Is a Condensate Pump? An air conditioner works by absorbing the warm air and humidity from your home. It then separates the moisture, which causes water droplets to drip into what’s known as a drip pan. Once the drip pan is full, the water is filtered out of your home through a pipe called the condensate line.

How to fix condensate pump not pumping water?

Step 1. Turn off your air conditioner. To be extra safe, shut off power at the breaker panel too. No sense in risking electric shock.

How does a water pump work?

The pump knows when to get the water out of your home because as the water level rises, it lifts the float. When the float is high enough, it hits a switch that powers the pump motor, which forces water outside.

How to fix a float on a furnace?

Step 2. Locate the pump. Next to the furnace, you’ll find a rectangular, plastic box that serves as a reservoir for the pump. Remove the top. The receptacle will be full of water. Remove the water to make it easier to troubleshoot. Step 3. Inspect the float.

Why is my air conditioner drain line disconnected?

It could be due to an improper installation or it can be due to the vibrations caused by the air conditioner over time . Whatever the case, a connection can loosen and the drain pipe can disconnect from the air conditioner.

What is the drain pan on an air conditioner?

In your air conditioner is a component known as the condensate drain pan. This pan catches any condensation runoff created within the air conditioner. The warm air that gets sucked into the unit (before it is turned into cool air) causes the moisture to evaporate.

How does a water float work?

The water float gauges how much water there is and sends a signal to the pump to turn on. It should move freely; clean out any gunk if it sticks. Check the impeller basket. Like the water float, the impeller basket, which is in a round shape and has slots, should be clean and free of debris.

Can an air conditioner stop working?

Your air conditioner, whether it is a small window unit or a large central unit, is a complicated piece of equipment. There are many components within it that, should they stop working, can derail the entire unit from working properly. From time to time, the condensate pump in specific will begin leaking water.

Can you clean a water pump that is dirty?

Otherwise, it will simply keep leaking and you will be back at square one. If it is simply a matter of the pump being dirty, you can easily clean the unit . Check the water float.

Is it important to schedule regular maintenance on HVAC?
