How to Pressure Wash an Air Conditioner

Pressure washing your air conditioner can help you keep it running efficiently and extend its lifespan. Here are the steps to follow:

Step 1: Prep the AC Unit

Before you begin pressure washing, turn off your AC unit and disconnect the power supply. This is an important safety measure. Next, remove any debris from around the unit and spray it with a cleaning solution to loosen any dirt or grime.

Step 2: Set Up the Pressure Washer

Fill your pressure washer with water and attach the appropriate nozzle for the job. For AC pressure washing, a 25-degree nozzle is recommended to avoid damaging the unit. Connect the pressure washer to a power supply and turn it on.

Step 3: Pressure Wash the AC Unit

Stand about 2-3 feet away from the unit and start pressure washing. Use long, sweeping movements to cover the surface of the unit, working from top to bottom. Be sure to spray in the direction of the fins, so you don’t push dirt or debris further into the system.

Once you’ve cleaned the surface area of the unit, turn off the pressure washer and allow the unit to dry for at least 2 hours.

Step 4: Reconnect Power and Turn On the Unit

After the AC unit has completely dried, you can reconnect the power supply and turn on the unit. Check the system to ensure that it’s running properly and that the fins are not bent or damaged.

That’s it! You’ve successfully pressure washed your air conditioner and increased its efficiency.

Best Practices for AC Pressure Washing

When it comes to pressure washing your AC unit, there are a few best practices to follow to ensure that the cleaning process is safe and effective. By following these tips, you can avoid damaging the sensitive components of your AC unit and achieve a thorough clean.

Tip #1: Use the Right Water Pressure

It’s important to use the right water pressure for your AC unit when pressure washing. Too much pressure can damage the fins and coils, while too little pressure may not be effective in removing dirt and debris. As a general rule of thumb, the water pressure should be no higher than 1,500 PSI (pounds per square inch) to avoid causing damage.

Tip #2: Choose the Right Cleaning Agents

When selecting cleaning agents for your AC unit, it’s important to choose ones that are safe for the specific materials used in your unit. Avoid using harsh chemicals or detergents that can cause damage or discoloration. Instead, opt for gentle, eco-friendly cleaners that are safe for use on sensitive components.

Tip #3: Avoid Direct Water Spray on Electrical Components

Electrical components, such as the fan motor and control box, are highly sensitive and should be avoided when pressure washing. Direct water spray can cause electrical shorts and other damage. To protect these components, cover them with plastic or other protective materials before pressure washing.

Tip #4: Use Protective Gear

When pressure washing your AC unit, it’s important to wear protective gear, such as safety goggles and gloves. This will help protect your eyes and skin from potential injury or exposure to cleaning agents.

Tip #5: Consider Hiring a Professional

While pressure washing your AC unit can be a DIY project, it’s always a good idea to consider hiring a professional for the job. A professional pressure washing service, such as Weber Power Washing in Wilmington NC, has the expertise and specialized equipment to ensure a thorough and effective cleaning while avoiding any potential damage to your AC unit.
