A Quick Guide to Air Conditioner Cleaning and Maintenance

The consistent running of your air conditioner during the summer means it’s highly likely your HVAC filters will become contaminated with atmospheric pollutants. These contaminants leave your unit clogged with dirt and debris, warranting regular cleaning and maintenance. Below are step-by-step instructions to ensure a clean and hygienic air conditioner system throughout the year.

5 Steps for Efficient Air Conditioner Cleaning

Get the Right Equipment

The essential items required for air conditioner maintenance include a toolbox, protective gloves, coil cleaners, spray washer, and a few washcloths. It’s also handy to keep a new air filter nearby so you can swap it out with the old one currently in use.

Turn Off the Power

To ensure proper safety, it’s important to disconnect the air conditioning unit from power until you’re done with the cleaning. Keep the system unplugged while you dismantle its components and clean them thoroughly.

Unscrew the Top Hood

With help from a suitable screwdriver, unscrew the fasteners attaching your AC’s top hood with its body. Carefully remove this plastic cover and examine the extent of contamination inside. As a first step, wash the top hood with utmost care and set it aside to air dry.

Clean Dirty Components

Employ coil cleaners to gently remove dirt and debris from your HVAC’s coils, clearing them away with warm water. Inspect the air filters and change them if they’re past the recommended usage period.

Put the Air Conditioner Back Up

Once all the essential parts are properly cleaned, it’s time to get your air conditioning unit back up. Put the coils and filters in their correct positions before covering them with the plastic hood and screwing it in place. Connect your air conditioner with an electric source and enjoy clean, fresh air once again.
