Goodman Air Conditioner Leaking [Proven Solutions]

Whether you find your Goodman air conditioner leaking water or freon, it is ideal to find a permanent solution. Fortunately, this article provides proven solutions to the problems.

Goodman Air Conditioner Leaking Water – Solved

The most likely reason your Goodman air conditioner is leaking water is the drain line. It may be obstructed by algae and dirt due to its position under the unit. Consider removing the drain pan and emptying it if it is overflowing. 

Use a wet-dry vacuum to clean the drain line out. Use the services of a technician if this method fails to work. Also, wash the drain pan and ensure it is not cracked. Consider putting an algae-fighting tablet in the pan to prevent future growth. An overflowing drain pan or clogged drain line will cause the air conditioner to leak water.

Other likely reasons your air conditioner is leaking water are:

1. Dusty Air Filter

Check the air filter in your Goodman air conditioner to see if it is significantly dirty. Replace the filter if it is or wash it. Typically, the filter will need a replacement once every month for the best results. But most users do not replace theirs as often. Hence, the freezing problem. 

A dusty filter will cause the unit to freeze because it will block the passage of cold air, which will get trapped within and cause freezing. And when the ice begins the melt, the water will overflow and leak out of the air conditioner.

2. Pulled-out Drain Line

Ensure the drain line is not disconnected from the unit. You can inspect it to make doubly sure; fix it back into position if it is. Puddles of water will form under the AC and the water will begin to flow out of the line is not fixed. If you are unsure of the steps to correct the error, have a technician take a look and fix it.

3. Insufficient Refrigerant

When the air conditioner is low on refrigerant, the cooling system will run non-stop to make up for the loss. As a result, the unit may freeze. Therefore, you may want to find out whether or not the unit has a leak. Such a leak must be found and fixed as quickly as possible if the AC must continue working optimally.

How to Tell If Your AC Is Leaking Freon

The following are some signs your air conditioner is leaking freon:

i. Reduced Airflow

The air conditioner cannot produce a lot of cold air when there is an insufficient amount of freon or refrigerant to make cold air. So, you may have a leak if the airflow is low, though a freon leak is not the only cause of the problem.

ii. Warm Air

A reduced amount of freon will affect how much cold air the unit produces. If it starts blowing warm air instead of cold, there may be insufficient freon in the system.

iii. Increased Electricity Bills

The air conditioner will work longer and harder to cool the house if the refrigerant is low. But that also means the unit will consume more energy than normal. A spike in your electricity bills may indicate that one or more appliances are running constantly and consuming too much energy.

iv. Iced-up Coil

When the evaporator coil has an ice buildup, it may mean that the freon is too low to absorb heat. The evaporator coil or copper lines may have to absorb the heat in its palace, and it causes condensation which freezes over time.

4. Condensation on Ductwork

The air conditioner’s ductwork may be leaking condensation, which may mean the ductwork needs to be examined. It needs proper insulation to prevent water from dripping onto the floor. You may want to hire a professional HVAC technician to check the ductwork and make necessary corrections.

5. No Drain Line or Pan

Sometimes, the air conditioner may be missing a drain line or pan. While this is rare, hence highly unlikely, you may want to check the line and pan in your unit to ensure they are in place. If they are, the line must be connected and the pan must be in place to catch draining water.

If nothing else seems to work, it is best to hire a technician to check the air conditioning system. Ideally, the AC should be regularly serviced to prevent any damages. Regular servicing helps to catch errors and damaged components before they cause greater damage to the air conditioner.

Goodman Air Conditioner Leaking Freon – What to Do

You should contact the manufacturer and request service if you find that your air conditioner is leaking freon. Alternatively, you can use a technician of your choice to find the leak and fix it if you have a trusted HVAC technician.

How to Find a Freon Leak in an AC Unit

You can always find a freon leak yourself, though it may not be so easy to fix it. Here are possible ways to find a freon leak:

Using soap bubbles: You can trace the leak by following the sound. It may be faint, but if the area is quiet and you pay close attention, you may hear it. Get soapy water and rub it along the line you suspect has the leak. If there is a bubble along the line, there is a leak and you can accurately pinpoint the spot.

Using a leak detector: If the detector is well-calibrated, it can detect a freon leak as quickly and accurately as possible. Using a detector is the most trusted and used means of finding a freon leak.

Using ultraviolet dye: You can add some UV dye to the freon in the system and with a UV light, find possible leaks. But the dye may reduce the efficiency of the freon in the future.
