Clearing Goodman Ac Drain Pan: Easy Steps To Follow

Keeping your Goodman AC drain pan clear is an important part of maintaining your AC unit. The drain pan collects condensation formed when warm air passes over the evaporator coils, and the drain line moves the water from the pan to outside your home. If the drain pan fills with water, it can lead to leaks, bacteria, and algae buildup, and water damage. To clear your Goodman AC drain pan, you can try using a wet/dry vacuum to clear clogs and debris from the system. You can also try pouring a gallon of water down the drain, using a funnel inserted into the PVC cleanout tee, to try and get things moving again. If you notice mold or algae buildup, you can rinse the line with boiling water.

Locate the drain pan

To locate the drain pan of your Goodman AC unit, you must first identify the indoor unit. The AC drain pan is located within the indoor unit, underneath the evaporator coils. Typically, the drain pan is situated on the same side as the air intake.

There are two types of drain pans: a fixed drain pan that sits directly under the coils, and an overflow drain pan positioned below the fixed pan. These pans collect condensation formed when warm air passes over the evaporator coils, preventing water damage to your home.

Regular inspection of the drain pans is important to detect leaks early on and prevent potential water damage. Even a small amount of leaked water can cause issues, such as warped floors and stains on walls and ceilings. Additionally, standing water in the pans can promote the growth of mould and bacteria, leading to potential health hazards.

Inspect the drain pan

To inspect the drain pan of your Goodman AC unit, follow these steps:

Locate the Drain Pan

First, locate the indoor AC unit. The drain pan is situated underneath the evaporator coils, typically on the same side as the air intake. There are two drain pans: a fixed drain pan under the coils and an overflow drain pan below that.

Turn on the AC and Allow it to Run

Turn on the central air conditioning thermostat and let the AC run for 20 to 30 minutes. This will help you identify any issues with water drainage.

Look for Water Around the Unit

After the AC has run for a while, carefully inspect the area around the indoor unit for any signs of water. Water pooling near the unit indicates a drainage problem.

Turn off the Power to the Air Conditioner

Before proceeding further, ensure you turn off the power to the air conditioner for safety reasons.

Remove the Access Panel and Inspect the Pans

With the power off, remove the access panel to gain better access to the drain pans. Use a flashlight to thoroughly inspect both the fixed drain pan and the overflow drain pan. Look for any cracks, dents, holes, rust, or signs of mold, algae, or bacteria buildup. These issues could lead to leaks and water damage, so it's important to address them promptly.

Check the Condensate Drain Line

Next, check the opening to the condensate drain line and the drain pipe. Typically, this is a 3/4-inch white PVC pipe. Ensure there are no obvious backups or debris blocking the pipe.

Inspect the Entire Drain Line

Visually inspect the entire drain line, both indoors and outdoors, for any signs of cracks or damage. Ensure that the drain line is properly directing water outdoors and there are no blockages or leaks along the way.

By regularly inspecting your Goodman AC's drain pans and condensate drain line, you can help prevent leaks, water damage, and the growth of bacteria and algae. It's important to address any issues promptly to ensure the optimal functioning of your AC unit and maintain a healthy environment.

Clean the drain pan

To clean the drain pan of a Goodman AC unit, you will first need to locate the pan. The AC drain pan is located in the indoor unit, underneath the evaporator coils, usually on the same side as the air intake. There is a fixed drain pan under the coils and an overflow drain pan below that.

Before cleaning the pan, you will need to turn off the power to the air conditioner at the breaker box. You can then remove the access panel to inspect and clean the overflow pan.

To clean the pan, you can use a rag or a wet/dry vacuum to remove any standing water and debris. If there is mould, algae, or bacteria in the pan, you can rinse it with a small amount of boiling water or a mixture of hot water, soap, and bleach.

To prevent future clogs, you can pour a cup of equal parts bleach and water down the drain or use a drain pan tablet to inhibit algae growth. You can also pour a cup of vinegar down the drain to help prevent clogs and kill mould, algae, and fungi.

Unclog the drain pipe

To unclog the drain pipe of your Goodman AC unit, you can try a few different methods:

• Use a wire hanger: Straighten a wire hanger and carefully snake it into the drain pipe to dislodge any clogs.
• Squeeze air into the pipe: You can use an empty water bottle or a shop vac to blow air into the pipe and clear any blockages.
• Flush with water: Pouring a gallon of water down the drain can help to clear clogs and flush out any debris. You can also try using a wet/dry vacuum to draw out the clog from the outside pipe opening.
• Use compressed air: This can be an effective way to clear clogs and debris from the drain pipe.
• Pour a cup of vinegar down the drain: This can help to kill mold, algae, and fungi, and prevent future clogs.
• Use a fin-straightening tool or a butter knife: Carefully insert this tool into the drain pipe to dislodge any clogs. Be careful not to damage the embedded tubing.

It is important to regularly inspect and maintain your AC unit's drain pan and condensate drain line to prevent leaks, water damage, and the growth of bacteria and algae.

Prevent future clogs

To prevent future clogs in your Goodman AC drain pan, regular maintenance is key. You should inspect your AC unit's drain pan regularly, as this can help with early leak detection and prevent water damage.

Firstly, locate your AC drain pan. This is found in the indoor unit, underneath the evaporator coils, usually on the same side as the air intake. There are two pans: a fixed drain pan under the coils and an overflow drain pan below that.

Turn the central air conditioning thermostat on and let it run for 20-30 minutes. Then, turn off the power to the air conditioner and remove the access panel to inspect the overflow pan. Use a flashlight to check the pans and note any cracks, holes, or signs of rust, mould, or algae buildup.

To prevent clogs, you can pour a cup of vinegar down the drain to stop the growth of mould, algae, and fungi. Alternatively, use a mixture of hot water, soap, and bleach to clean the drain pan. You can also place a drain pan tablet in the pan to prevent algae growth.
