Outdoor dirt can cause big issues with your air conditioner. If you don't clean your condenser coils, you'll end up with a hot and humid house.

Dirty outdoor coils can lead to discomfort, as your AC might not cool your home effectively. This can be especially frustrating during the hottest months of the year.

The problem starts when dirt, pollen, and other outdoor grime build up on the condenser coil. This reduces the system's ability to remove heat from your home, causing it to work harder and use more energy.

Here are the specific problems you can expect if you don't clean your outdoor coils:

Cleaning your outdoor coils can help prevent these issues and ensure your AC runs efficiently.

The evaporator coil is a crucial part of your air conditioning system, responsible for cooling the air that circulates through your home. It's typically located indoors, near the air handler.

The evaporator coil runs through aluminum fins, similar to condenser coils, and is designed to send cool air into your house. As the refrigerant passes through the condenser coils, it moves indoors to the evaporator coils, where it expands into a gas and cools down the coils.

To clean the evaporator coils, you'll need to access them through a panel secured by a few screws. Once you've removed the panel, you can use a soft-bristled brush to gently remove any hair or debris that's accumulated on the coil.

You can use coil cleaner to spray the coil and let the foam do the work. Be sure to wear gloves while handling the cleaner, as it's acidic and can hurt you. After using the cleaner, rinse the coil with water, either by turning on your AC or using a spray bottle.
