Power washing your AC unit is a simple yet effective way to maintain its efficiency and performance. Regular cleaning can help remove dirt, dust, and debris that can clog the unit's coils and reduce its ability to cool your home.
A dirty AC unit can increase your energy bills and cause your unit to work harder, leading to premature wear and tear. This can result in costly repairs or even the need for a new unit.
The average AC unit can lose up to 5% of its efficiency for every 1/100th of an inch of dirt that accumulates on its coils. This means that a dirty AC unit can end up costing you up to $150 more per year in energy bills.
Regular power washing can help prevent these issues and keep your AC unit running smoothly.

Why Clean the AC?
Cleaning your outdoor AC unit is crucial for its proper functioning. It's recommended to clean it once or twice a year to prevent dirt accumulation.
A dirty outdoor AC unit can affect other parts of the system, such as the condenser fan, fan motor, air handler, and evaporator coil. This can lead to a breakdown if left unchecked.
Cleaning your outdoor AC unit can save you from energy waste and potential AC unit breakdowns. If the refrigerant can't absorb heat, the machine will have to work harder, consuming more electricity and potentially leading to a breakdown.
Here are the reasons to clean your outdoor AC unit:
- The parts of the AC units are interdependent, and a dirty outdoor condenser unit can affect other parts.
- The outdoor condenser coils are responsible for cooling down the hot refrigerant, and dirt and debris can prevent proper airflow.
- A dirty outside air conditioner wastes energy and can lead to AC unit breakdowns.
What's Wrong with Washing an AC?
Washing an AC can cause serious damage to the fins and coils, which can bend and lose their shape due to the high-pressure water jets. This can lead to reduced airflow and efficiency.
Power washing an AC can also breach the seals, allowing dirt and debris to enter the system and cause further problems.
The force of the water jets can dislodge and spray debris over the system, including dirt, dust, and other contaminants that can clog the unit.
Dirty Outdoor Air Conditioning Unit Problems
A dirty outdoor air conditioning unit can cause a range of problems, from reduced performance to increased energy bills.
The parts of the AC units are interdependent, so if your outdoor condenser unit is dirty and malfunctioning, it will affect other parts such as the condenser fan, fan motor, air handler, and evaporator coil.
A dirty outdoor condenser coil can prevent proper airflow, causing the refrigerant to retain heat instead of cooling it down. This can leave your house hot, even when the AC is running.
Working harder and for longer to achieve the set temperatures on your thermostat can waste a lot of energy. In fact, a dirty outdoor air conditioner can consume more electricity, leading to higher energy bills.
If your cooling system is overworking due to dirt and debris build-up, there will be a breakdown soon. You may soon have to call for air conditioning repair services to fix a broken down AC to ensure it is working correctly again.

Here are some specific reasons why a clean outside air conditioner is necessary during a cooling season:
- The refrigerant won’t be cooled if dirt and debris prevent proper airflow around your outdoor system.
- The outdoor condenser coils are responsible for cooling down the hot refrigerant.
- A dirty outside air conditioner wastes energy.
- AC unit breakdowns: If your cooling system is overworking due to dirt and debris build-up, there will be a breakdown soon.
Cleaning the AC Unit
Cleaning the AC Unit is a crucial step to ensure your air conditioner runs efficiently and effectively. To start, you'll want to clear any loose debris and plants around the outdoor unit.
Before you begin, switch off the power to the AC unit to avoid any accidents. This is a safety precaution that's essential to remember.
If you notice bent fin combs, use a fin comb to straighten them out. This will help improve airflow and prevent damage to the unit.
Next, vacuum down any loose dirt from top to bottom, or use a soft brush to gently sweep away debris. This will help you get into tight spaces and remove dirt that's accumulated.
For stubborn dirt, use a no-rinse coil cleaner or foam cleaner to loosen it. These types of cleaners are specifically designed for outdoor AC units and can help break down tough grime.

Let the cleaner soak in for approximately 10 minutes before hosing it down repeatedly until it's clean. This will help ensure the dirt is fully removed and the unit is clean.
Here's a step-by-step guide to cleaning your outdoor AC unit without removing it:
- Clear any loose debris and plants around the outdoor unit
- Switch off the power
- Use a fin comb to straighten bent fin combs
- Vacuum down loose dirt from top to bottom, or use a soft brush
- Hose down any stubborn dirt
- Use a no-rinse coil cleaner or foam cleaner to loosen stubborn grime
- Let the cleaner soak in for approximately 10 minutes and then hose it down repeatedly until it is clean
Pre-Cleaning Steps
Before you start power washing your AC unit, it's essential to take some pre-cleaning steps to ensure a safe and effective cleaning process. Clear any loose debris and plants around the outdoor unit.
Loose screws can cause your AC unit to make loud noises, so it's best to clean it without removing or unscrewing it. Switch off the power to the unit to avoid any accidents.
Make sure to clear any debris from the sides of the condenser, as leaves, pine needles, and other debris can collect around the unit and restrict airflow. Even the fluff from poplar trees, cottonwoods, and dandelion seeds can cause problems.
Here's a quick rundown of the pre-cleaning steps you should take:
- Clear any loose debris and plants around the outdoor unit.
- Switch off the power to the unit.
- Clear debris from the sides of the condenser.
By following these simple steps, you'll be able to power wash your AC unit safely and effectively. Remember to clean your outdoor AC unit once or twice a year to ensure it's running properly.
Cleaning Process
Cleaning your AC unit can be a daunting task, but it's essential to keep it running efficiently. You can start by clearing any loose debris and plants around the outdoor unit.
To begin the cleaning process, switch off the power to the unit. This is crucial to avoid any accidents or damage. Make sure to unplug the unit or switch off the circuit breaker.
A fin comb can be used to straighten bent fin combs, which can help improve airflow. Vacuum down any loose dirt from top to bottom, or use a soft brush to gently sweep away debris.
If you have stubborn dirt, you can use a no-rinse coil cleaner or foam cleaner to loosen it. Let the cleaner soak in for approximately 10 minutes before hosing it down repeatedly until it's clean.
To ensure a thorough clean, you can use a foam coil cleaner on the condenser coils. This will help break down dirt particles, making it easy to wash them off.
