Unclogging an evaporator in a car can be a complex process. The first step is to accurately identify the issue and the blocked component within the system. You can do this by visually inspecting the evaporator, particularly the louvers and outlet temperatures.
If the blockage is suspected then you can use a tester to verify the level of obstruction.
Once identified you need to remove the evaporator from the system by disconnecting the electrical connectors, refrigerant lines and mounting plates. If necessary, you can use a special extractor to remove any dirt or debris from the evaporator.
To unclog the evaporator, you should first use a vacuum cleaner to remove any dust, dirt, or other debris from the evaporator. Be sure to pay special attention to the louvers, outlet of the evaporator, and the air filters.
You can also use compressed air to blow off any excess debris or dirt. Make sure to take safety precautions while using the compressed air to avoid damaging any components.
Next, use a soft brush or brush attachment on a vacuum to mildew and fungi deposits. If stubborn deposits remain, you may use a chemical cleaner such as brake cleaner or diluted chlorine bleach. However, be sure to wear a mask and protective goggles when doing so.
Once all deposits are removed, it is important to thoroughly flush the evaporator and ensure there are no remaining deposits. This can be done by using air or a chemical cleaning solution made specifically for evaporator cleaning.
Finally, before reinstalling the evaporator, be sure to test the functionality of the evaporator by running it through a few cycles. This will check the functionality of the evaporator and the system so that it can work properly.
How do I clean my evaporator coils without removing them?
Cleaning the evaporator coils without removing them can be done with a few simple steps. First, turn off the power to the unit then remove any panels that house the coils. Next, use a soft-bristled brush to carefully brush away dirt, debris, and other build-up from the coils.
If necessary, you can also use a vacuum cleaner hose attachment to further remove dust and debris from the evaporator coils.
Once the visible build-up has been removed, you can use a coil-cleaning solution to further clean the coils. These solutions are typically made up of a mix of water and an alkaline or neutral detergent.
Spray the solution onto the evaporator coils and allow it to sit for 15-30 minutes before wiping off the excess. If necessary, use a soft cloth dampened with water to remove any extra solution. Allow the coils to dry before putting the panels back in place and turning the power back on.
What happens when an evaporator becomes blocked?
When an evaporator becomes blocked, it can no longer effectively cool and circulate air throughout the home/building. This can lead to an increase in humidity levels, as warm air is created but unable to move out of the environment.
Extreme temperatures are also possible, depending on where the blockage is located. If the blockage is near the compressor, the airflow to the evaporator coil can be completely cut off, meaning the unit will struggle to cool the home/building.
In addition, if the blockage is in the drain pan, excess water can accumulate, resulting in water damage and potential electrical shocks due to exposed wiring. To prevent these issues, an HVAC technician should be called to inspect the system and replace any blocked or damaged components.
What are the symptoms of a dirty evaporator coil?
The most common symptom of a dirty evaporator coil is a decrease in cooling power. If the evaporator coil is excessively dirty, it will not be able to absorb heat from the air as efficiently as when it is clean.
This can result in decreased air circulation, and you may notice air coming from the vents that isn’t as cold as it should be.
Other symptoms of a dirty evaporator coil include noises such as hissing, grinding, and rattling coming from the air conditioning system. You may also notice an increase in humidity as the evaporator coil is responsible for pulling moisture from the air.
In more serious cases, you might also experience a musty odour coming from the vents due to mold and mildew growth on the dirt that has built up in the coil.
How much does it cost to have evaporator coils cleaned?
The cost of evaporator coil cleaning can vary depending on the size and complexity of the job. Generally, the cost can range from $100 to $400.

You can also use a brush to agitate the coil and help the cleaner reach deep into the fins. Once this is done, you can either rinse the coil with water or blow it out with compressed air. If the evaporator coil needs a more thorough cleaning, you may need to remove it from the system and use a coil cleaner that is specifically designed for this purpose.
Is it OK to spray water on your air conditioner while running?
No, it is not generally recommended to spray water on your air conditioner while it is running. This is because water and electricity are a potentially dangerous combination, and you could end up causing damage to your air conditioner or even put yourself at risk for an electric shock.
Additionally, spraying water on air conditioners can cause the unit to malfunction or even stop working altogether. If you need to clean your air conditioner, it is best to turn it off and then use a damp cloth to wipe the outside, never spray it with a hose or use high-pressure water systems.
Will a dirty coil affect cooling?
Yes, a dirty coil can significantly affect cooling. The coil, also known as an evaporator or condenser, is responsible for transferring heat between the air and refrigerant in a cooling system. The coil is filled with a special refrigerant that is able to absorb heat from the air and transfer it outside.
If the coil is not cleaned regularly, then dust, dirt, and debris accumulate on the surface and prevent the refrigerant from absorbing heat from the air. This blocks heat transfer, leading to an inefficient cooling cycle.
In addition, dirt and debris left on the coil over time causes corrosion and reduces system effectiveness, which can lead to increased energy costs and shorten the life of the system. Therefore, it is important to clean the coils regularly to prevent any harm to the cooling system.
