  • ​Top Respected Brand
  • Easy to Set Up
  • Professional-Grade Design
  • Fast-Acting Results

This very high quality condensate pump made by Little Giant is a powerful pump with a 1-gallon tank, state-of-the-art features, and a well-designed look. It’s ideal for residential properties and quietly removing condensate without hurting the HVAC system’s overall performance.

What Are Air Conditioner Condensate Pumps?

A condensate pump is designed to remove condensate (water) from an HVAC system.

When the air conditioning unit begins to work, it naturally produces condensate or small droplets of water. These droplets can start to collect and ruin the A/C, if not removed right away using a drain or condensate removal pump. This pump ensures the air can pass through the coil, leave droplets of water, and continue through without being stopped.

With a functional furnace condensate pump, the water has nowhere to go and remains trapped.

In general, there’s a separate drain pan designed within A/C units to collect excess moisture from the evaporator coil. While certain HVAC systems can automatically push the water towards a drain, others cannot. This is when it’s time to consider investing in a proper ac condensate pump.

When the condensate pump is in place, it can help remove the water without getting in the way. This makes sure water doesn’t leave a mess on the floor.

A residential setup often requires a 120-volt condensate pump to handle the additional moisture. When the condensate pump doesn’t produce enough power, it leaves water in the drain pan, which can damage the A/C or fill the room with puddles of water. 

For the average property owner, it is highly recommended to assess whether or not their A/C has a condensate pump or a draining mechanism. If not, it’s best to invest in a professional-grade condensate pump as soon as possible.

The condensate pump may come with specific features.

These features can include a tank (0.5-1 gallon), which helps pump the water away from the A/C unit. To maximize its effect, the condensate removal pump is positioned right under the A/C unit or on top of the main drain pan. This makes the removal as quick as possible.

Additional features include a float switch. This switch helps figure out when there’s too much water in the drain pan and it needs to be drained. Once activated, the pump goes to work and removes the water.

What are the Benefits of AC Condensate Pumps?

Condensate pumps are essential for several reasons and it’s important to invest in the right one immediately.

To learn more about the value of a new pump, let’s take a look at the main advantages of buying one.

The benefits include:

  • Quick Removal of Excess Water
  • Increased Efficiency
  • Maintains Consistent Performance
  • Reliable Removal of Water To a Drain

With a powerful, well-designed condensate pump, it’s possible to see consistent results without having to make changes. This is essential when the A/C is producing too much water and is being used all the time.

The more an A/C unit is used, the more water it’s going to leave behind. This makes it doubly important to buy the best condensate pump.

How to Install a Condensate Pump

Newer properties come with a pre-designed drain to collect water coming from the HVAC system. The drain is often located closer to the main unit and ensures the water drips into the drain without leaving a mess.

However, older properties do not come with a pre-designed drain. This means a self-installed solution such as a furnace condensate pump becomes essential. It’s the only way to make sure the water doesn’t spread throughout the room.

To install a condensate pump, it needs to be placed alongside the main unit. It will have to come equipped with a drain line (sink, floor drain), which will ensure the water is directed to where it needs to go.

It’s important to install the unit in a place where any malfunction doesn’t damage the system or the property. There should be enough space to set up the air conditioner condensate pump without getting in the way of the A/C unit.

The condensate pump installation process begins by unplugging the main unit, disconnecting the drain line, and emptying the existing water. From this point forward, it’s time to work on the valve and plug in the pump.

Once in place, the ac condensate removal pump can be activated. It will continue to run in the background and help remove excess water as it builds up in the main drain pan.

How to Pick the Best Condensate Pump?

1. GPM (Gallons per Minute) Rate

This measurement is critical in determining how much water can the pump remove per minute. To determine this number, each unit comes with a pre-determined or pre-tested GPM rate.

The GPM rate lists how many gallons can be removed per minute once the pump is activated.

In general, the average ac condensate pump can remove twice the amount of condensation depending on its tank size. As a result, it’s best to invest in a unit with at least a 1-gallon tank for maximum results.

2. Voltage

Depending on the system, a certain amount of power is needed to remove water from the drain pan. With a traditional residential unit, it’s acceptable to use a 120 volt outlet.

For larger units, the system may require a 220 volt outlet for more power.

It’s important to assess the property’s needs along with how much condensate is produced by the A/C unit.

3. Horsepower

The amount of horsepower generated by the hvac condensate pump can help determine how much water it can pump out. In most cases, the average residential condensate pump is going to have no more than 1/30-1/50 hp.

With larger units, the furnace condensate pump may offer up to 1/3 hp.

Just like the voltage, it’s important to begin by assessing the property’s HVAC system and how much condensate it produces per day. This can help determine how much horsepower is required to keep the system in check.

4. Measurements

Measure the pump to make sure it can be placed next to the A/C unit.

Remember, the condensate pump needs to be installed on or next to the drain pan and will actively remove excess water once the HVAC is operating. This means it needs to have enough space so the pump doesn’t get in the way or so the drain line doesn’t get damaged.

5. Durability

How durable is the air conditioner condensate pump?

The best a/c condensate pump should be made of high-grade materials such as galvanized steel. This is the only way to make sure the pump doesn’t break down as soon as the HVAC system produces condensate.

When a condensate pump can’t remain durable, it starts slowing down. This can compromise the system, how it performs, and how consistent it is throughout the day.

What Are The Main Differences Between Sump Pumps?

The primary reason for investing in a brand-new condensate pump is to remove excess water.

However, not all condensate pumps are the same. There are variations available on the open market and it’s important to determine the differences. This helps shed light on what works and what doesn’t when it comes to HVAC systems.

Here’s a detailed assessment of the different types and how they function.

  • Design

It starts with the pump’s design.

The average pump comes in two types – dynamic and positive displacement.

With dynamic pumps, the emphasis is on using the water’s force (momentum) to push the water where it needs to go. This is often seen with electric-powered hvac condensate pumps, when the water is produced at higher rates. In some situations, the water is reused depending on how the pump is setup.

On the other hand, positive displacement pumps are all about opening and closing as water collects in the drain pan. This ensures the water continues to be pumped out consistently.

Along with these types of pumps, there are additional options involving the use of steam or compressed air. When activated, these systems can help maintain pressure as the water travels through to the other side.

  • Specifications 

It’s also important to note the different specifications available through different pumps.

These specifications can differ based on pressure, power ratings, pump heads, flow rates, diameter measurements, and the operating temperature.

The materials used to create these pumps can also be included in the differences. Some are made of plastic while others are made of galvanized steel. This can make a noticeable difference on how the pump works, how much pressure it can sustain, and how long it lasts once installed.
