How to Clean Goodman Ac Coils

ByRalph P. Sita Updated onFebruary 10, 2025

To maintain optimal performance of your Goodman air conditioning unit, it is crucial to regularly clean the AC coils. Routine maintenance, specifically targeting the condenser and evaporator coils, helps prevent efficiency loss and prolongs the lifespan of your system.

Before you begin the cleaning process, ensure the power source is unplugged to eliminate any electric shock risks. First, utilize a vacuum cleaner equipped with a brush attachment to eliminate dirt and debris from the surface of both the condenser and evaporator coils.

Next, prepare a solution of warm water and mild detergent in a bucket. With a soft cloth or sponge, carefully clean the exposed metal components of the coils, and rinse thoroughly with plain water. Allow the coils to dry completely before powering the unit back on; you may also consider using a specialized AC cleaner for effective results.

Lastly, check for any signs of rust around the coils. If rusty areas are present, you may need to use rust removal products or sandpaper to restore the affected areas. By following these steps, you can ensure your Goodman air conditioner operates efficiently and effectively.

Can I Clean My Own Air Conditioner Coils?

Yes, you can clean your own air conditioner coils!

It is an important part of regular maintenance to keep your unit running efficiently and extend its lifespan.

Before you begin, switch off the power at the main breaker box to ensure safety.

Then remove any debris or dirt from the outside condenser unit using a vacuum cleaner or brush.

Next, use either a garden hose or coil cleaning solution and a foaming sprayer to thoroughly wash away any particles on the fins and evaporator coils.

Afterward, rinse with water until all soap residue is gone then dry completely before replacing the access panel and powering up again.

While it may seem like a daunting task at first, with some patience, carefulness and proper tools anyone can successfully clean their air conditioning unit’s coils themselves.

How Often Should You Clean Ac Coils Inside?

When it comes to properly maintaining your air conditioner (AC) unit, one of the most important tasks is cleaning the AC coils.

The evaporator and condenser coils collect dirt over time that can reduce their efficiency and cause your energy bills to increase significantly.

To keep them working efficiently, you should clean your AC coils inside at least once a year or even more frequently if necessary.

Cleaning a dirty coil will also help prevent corrosion which can damage other components in the system.

If you don’t feel comfortable doing this yourself, then consider hiring an HVAC professional who has experience with these types of systems and knows how to safely perform maintenance on them.

This way you can be sure that your AC is running as efficiently as possible while also avoiding any potential problems related to improper maintenance or repair work.

What is the Best Way to Clean Hvac Coils?

The best way to clean HVAC coils is a three-step process.

First, it’s important to remove any loose debris from the coil.

Vacuuming or using compressed air are both good techniques for this step.

Second, use a mild detergent solution and brush the coil with a soft bristle brush while spraying the solution onto it.

Rinse off the soap after cleaning with water and allow it to dry completely before reassembling your HVAC system components.

Finally, you should apply an anti-corrosive coating such as silicone lubricant or oil on the coil surfaces to protect them from oxidation and corrosion in future operations of your HVAC system.

With these steps, you can ensure that your HVAC coils remain clean and free of dust buildup so they will operate efficiently for years to come!
