How To Effectively Maintain A Goodman Air Conditioner’s Coils

During the scorching summer months, owning a Goodman air conditioner can be a lifesaver. However, to ensure optimal cooling performance, regular cleaning of the coils is essential. In this article, we have conducted extensive research to provide you with a comprehensive guide on how to clean the coils of a Goodman air conditioner. By following the step-by-step instructions outlined below, you can effectively maintain your air conditioner and prevent potential damage.

Step 1: Turning Off The Device
Before beginning the cleaning process, it is crucial to turn off the air conditioner. Additionally, you should unplug the power sources by switching off the circuit breaker and disconnecting the power at the outside disconnect box for safety purposes.

Step 2: Removing The Screws
Using a flathead screwdriver, carefully remove the screws that secure the cover of the AC condenser unit. Take caution not to damage the coil or power wires while doing so.

Step 3: Vacuuming The Dirt And Debris
Once the cover is removed, employ a hose or brush to vacuum the accumulated dirt and debris on the coils. Fortunately, the design of Goodman condensing units allows for easy cleaning without the need to remove the entire unit.

Step 4: Cleaning The Coils With Water
After removing the dust and debris, it’s time to clean the coils. You can either use a coil cleanser or make your own by combining white vinegar, warm distilled water, and mild dishwashing soap in a spray bottle. Spray the coil cleaner onto the coils and allow it to soak for a while. Then, rinse the coils with a hose, ensuring that the water drains clear before shutting it off. Avoid using a power washer or pressure washer on the delicate fins as they may bend or distort under high pressure.

Step 5: Reconnecting The Circuit Breaker And Disconnect Box
Once the cleaning is complete, reattach the screws to secure the condenser unit’s cover. Additionally, reconnect the circuit breaker and the disconnect box outside your home.

Step 6: Activating The Thermostat
Lastly, turn on and reset your thermostat. For optimal efficiency, it is recommended to set the thermostat to a consistent temperature of 78°F.

Understanding Dirty AC Coils

During the refrigeration process, AC coils naturally accumulate dirt. Over time, the condenser coil collects debris and dirt from the surrounding environment, such as grass trimmings, lint from clothes dryers, leaves, fur, and dust.

Signs Of Dirty Coils

Several indicators suggest that your condenser coils need cleaning:

1. Frost formation on the coils during operation, hindering the flow of cool air.
2. Reduced cooling capacity, resulting in less cold air being produced.
3. Increased time taken by the unit to reach the desired temperature due to decreased cooling efficiency.

Frequency Of Coil Cleaning

As a general guideline, it is advisable to clean your AC coils at least once a year. However, if you reside in a polluted, windy, or dusty area, more frequent cleaning may be necessary. The frequency of cleaning also depends on the age and usage of your air conditioner. Older units or those used consistently will accumulate dirt faster and require more regular cleaning.

Tips For Coil Cleaning

To keep your AC coils clean, it is important to regularly replace the air filter, ideally on a monthly basis. Additionally, ensure the area surrounding the coil is free from dirt, debris, grass clippings, and other obstructions.

Professional Coil Cleaning Costs

If you opt to have a professional clean your AC coils, the cost will vary depending on factors such as accessibility, coil type, location, and the amount of dirt buildup. Basic cleaning costs for evaporator coils typically range from $100 to $400, while removal and cleaning can cost between $400 and $700. A condenser coil cleaning typically costs between $75 and $230.

Timeframe Before Turning On AC After Coil Cleaning

It is safe to turn on your AC unit approximately one hour after cleaning the coils.

Lifespan Of Air Conditioner Coils

The lifespan of air conditioner coils depends on usage and maintenance. With regular proper maintenance, the coil can last approximately 10-15 years.

Conclusion

Proper maintenance of your Goodman air conditioner coils is crucial for maintaining its cooling efficiency and preventing potential damage. By following the step-by-step cleaning process outlined in this article, you can ensure optimal performance and longevity of your air conditioning unit. Remember to clean your AC coils regularly, replace air filters, and keep the surrounding area free from debris to maximize efficiency and minimize the risk of malfunction.
