What You'll Learn
When to replace a drain pan
There are several reasons why you may need to replace a drain pan.
Firstly, if your drain pan is part of a central air conditioning system, it will be located below the cooling coils. As warm air passes over the cooling coils, moisture accumulates and drips into the drain pan. If the pan becomes clogged, rusted, or damaged, it will need to be replaced to prevent water from leaking and causing damage to your home. Regular maintenance will help prevent mould and cracks.
Secondly, if your drain pan is a washing machine drain pan, you may need to replace it if you are installing a larger washing machine that will not fit in the current drain pan.
Additionally, if your drain pan is a secondary condensate drain pan, it is fairly simple to replace. However, if you need to disconnect anything other than the power to the unit, it is recommended to call a professional.
Finally, it is not recommended to replace a primary drain pan as it is often attached to the main part of the system. Removing it could be dangerous or cause damage to the system. If your primary drain pan is overflowing, you can take steps to prevent water damage, such as using a sump pump to remove water or moving items that might be damaged by water.

How to remove the old drain pan
Removing an old drain pan can be a challenging task. It is important to note that the process may vary depending on the make and model of your unit. Here is a step-by-step guide to help you remove an old drain pan:
Shut off the power supply: Before beginning any work on your drain pan, it is crucial to ensure your safety. Locate and shut off the power supply to your A/C unit or furnace. This will prevent any accidental activation during the removal process.
Remove the front panel: Accessing the drain pan often requires removing the front panel of the unit. Typically, this can be done by simply pushing up or pulling the panel away from the unit. In some cases, you may need to remove additional panels or disconnect certain pipes or ducts to gain better access to the drain pan.
Locate the drain pan: The drain pan is usually located below the cooling coils in the air handler or furnace. It may be hidden from plain sight, but its position relative to the cooling coils can guide you.
Disconnect the drain tube: Look for the drain tube connected to the drain port on the pan. Use a screwdriver to loosen and remove the clamp securing the drain tube to the drain port. Have a small pan nearby to catch any residual liquid that may be present.
Loosen and remove screws: Check for screws near the front of the condensate pan that attach it to the air handler or furnace. If screws are present, use a screwdriver to loosen and remove them. In some cases, the pan may be welded to the cooling coils, which will require replacing the entire cooling coil assembly.
Remove the old drain pan: Once the screws are removed, carefully grip the condensate pan and pull it forward to remove it. If the pan is resistant or difficult to move, use a pry bar to gently pry it away from the unit. Be cautious not to damage any surrounding components during this process.
It is important to note that removing the primary drain pan is not recommended, as it may be attached to the main part of the system. Always exercise caution and seek professional assistance if you are unsure about any part of the process.

Purchasing a new drain pan
When purchasing a new drain pan, it is important to consider the size, material, and compatibility with your AC unit. Drain pans come in various sizes, so you need to ensure that you select one that fits your unit properly. You can refer to the make and model of your AC unit to find the appropriate size of the drain pan.
Drain pans are typically made of materials such as plastic, PVC, stainless steel, or aluminium. Aluminium is a popular choice due to its durability and resistance to rust and corrosion. It is also lightweight, making it easier to install and handle.
You can purchase drain pans from local home improvement stores or online retailers. Some stores may even offer custom-made or fabricated drain pans to ensure a perfect fit. When buying a new drain pan, it is advisable to inspect your current drain pan setup and take note of any issues, such as rust or leaks, to ensure that you address them with the new installation.
The cost of a drain pan can vary depending on the model of your AC unit and the specifications of the new pan. Basic drain pans can start from around $30, while the cost of replacing a drip pan in an AC unit can range from $200 to $600.

Installing the new drain pan
Before installing a new drain pan, ensure that you have shut off the power supply to your A/C unit. If there is any water in the drain pan and drain line, remove the water first before replacing the pan. Use paper towels, cloths, or tissues to absorb the water.
Now, you can begin installing the new drain pan. Slide the new drain pan into place, ensuring that the drain port is sticking through the side of the air handler. If your old drain pan was screwed in place, replace the screws that hold the pan to the unit. Put the drain tube and clamp in place and tighten the clamp with a screwdriver to secure the drain pipe.
Replace the outside panel. Your secondary pan should always be installed in a way that makes it easy to access and monitor. The purpose of this pan is to make it easier to ensure that the primary drain pan is working correctly. Slide the cover back over the cooling coils and push down on it to lock it onto the air handler.
Finally, restore the power back into your unit.

Maintenance and troubleshooting
Maintenance:
- Regularly inspect the drain pan for any signs of damage, including cracks, rust, or corrosion, especially along the edges and corners, which are more susceptible to damage.
- Keep the drain pan clean and free of debris. Remove any dust, dirt, or algae that may accumulate over time, as this can obstruct water flow and cause clogs.

- If your appliance has a built-in fan, regularly check its functionality to ensure it facilitates proper air circulation.
- Schedule annual maintenance with a qualified HVAC technician. They will inspect the drain pan and drain line, identify potential issues, and recommend necessary repairs.
Troubleshooting:
- If the drain pan is not flowing properly, examine it for any visible damage, such as cracks or rust.
- For minor cracks, use epoxy or sealant to patch them and prevent further damage.
- If the drain pan is extensively damaged, rusted, or corroded, replacement is typically the best option. Consult a professional for guidance on selecting and installing a suitable replacement.
- In the case of a clogged drain line, locate the line and assess its condition. Use a wet/dry vacuum or a pipe brush to gently remove any debris or buildup obstructing water flow.
- If the drain pan is tilted, adjust its position to ensure proper drainage and prevent overflow.
- If the refrigerant in your air conditioning system is too cold and forming ice, adjust the temperature settings to prevent ice buildup.
- In the event of water accumulation or overflow, use a sump pump to remove the standing water and prevent potential water damage.
- If mould is present in the drain pan, handle it with caution and take the necessary steps to remove and prevent future mould growth, such as improving airflow and maintaining dryness.
Remember, safety should always come first. If you are uncomfortable performing any maintenance or troubleshooting tasks, don't hesitate to contact a professional technician for assistance. They have the expertise and equipment to handle more complex issues and ensure the safe and proper functioning of your drain pan system.

Frequently asked questions
If your drain pan is visibly cracked, it is a good idea to replace it. While you can temporarily repair a cracked drain pan with tape and sealant, it is not a long-lasting solution. You should also replace your drain pan if it is stained by mold or rust, or if it has an unpleasant smell, as this can be detrimental to the indoor air quality of your space.
First, shut off the power supply to your A/C unit. If there is any water in the drain pan, use a paper towel, cloth, or tissue to absorb the water. If there are any screws or clips holding the pan in place, loosen and remove them. If there are no screws, or the pan does not move easily after removing the screws, the pan may be welded to the cooling coils, in which case you will need to call a professional. If the pan is not welded, try pushing the drain port toward the inside of the air handler to loosen the pan, then slide out the old pan and insert the new one. Replace the screws or clips, and put the drain tube and clamp in place, tightening with a screwdriver.
The cost to replace a drain pan is typically between \$200 and \$600, depending on the model of your unit and the specifications of the new pan.
