How long should you let an air conditioner dry after cleaning?

Discovering how long filters and condenser coils need to dry after cleaning an air conditioner before you can use the unit, and how to clean filters and coils.

Overview

Having a well-functioning air conditioning unit means giving it proper attention and care. The components of your air conditioner need to be well looked after to ensure that the unit is performing optimally all the time, and a major part of this is keeping the air conditioner clean.

There are sensitive parts of an AC unit that need to be kept in a good condition and if they are not, it can lead to your unit malfunctioning and causing you unnecessary trouble and expenses. Cleaning these components is important and needs to be done carefully.

Drying an air conditioner after cleaning

Some components of the air conditioner need to be cleaned with water. After cleaning these components, namely, the coils and the air filter, you need to allow them a certain amount of time to dry properly before you can reinstall particularly the filters and switch on the air conditioner again for  use.

It is important that you allow time for drying as you cannot reinstall the filters into the AC unit or switch the unit back on if the coils are still wet or damp.

How long should you let an air conditioner dry after cleaning?

After cleaning either the coils or filter of an air conditioner, you need to allow them to dry properly. This is because using the AC unit while these components are still moist can cause major damage to your unit, which is what you were trying to avoid in the first place.

It is important to note that drying times vary depending on the type of filters and coils of a unit. Typically, filters need approximately eight to 10 hours to dry. Coils can take approximately 60 minutes or more to dry.

In both cases, you should first check to ensure complete dryness of these components.

Cleaning the condenser coils

Bear in mind that each unit and scenario are unique. Ensure the unit is completely disconnected from the power and remove the grille carefully.

Remove any trapped debris collected at the bottom of the unit and dilute your cleaning solution according to its instructions, then add it to the pump sprayer.

Spray it onto the coils and allow some time for it to foam up. Wash it off with a low-pressure hose, then straighten any bent fins with a fin comb, clean around the unit, and replace the grille.

How to clean the air filter

Make sure you consult your instruction manual to be safe before proceeding with a filter clean. Locate the filter, remove it according to instructions, and vacuum it gently using an attachment without a brush.

Soak it in a soapy, room-temperature water solution for 10-15 minutes or hose it down. Then make a vinegar and water solution to spray on both sides of the filter for 10 minutes to kill bacteria and rinse the filter.

Allow the filter to air-dry for a couple of hours before you reinsert it.

Considerations on cleaning your air conditioner

Not all air conditioning units are the same, so it is best to ensure you consult your user manual to be sure you are removing components like filters from your unit correctly. It is safer to be guided by the manual.

Never rush the process by inserting a filter that has not dried fully or running the unit without the filter. This can be dangerous and ineffective and can counteractively damage your unit.

Finally, always ensure that both the filter and coils are dry before turning your air conditioner on again.

Final thoughts

Part of having an air conditioner means making sure you are maintaining it well to keep it operating at its best. This means that important components that influence the functionality of your unit need to be cleaned and taken care of to ensure optimal and efficient performance.

Filters and condenser coils need to be cleaned to maintain an air conditioner. This will require the use of water, so it is important that you allow a few hours for filters and coils to air-dry before you can get back to using your unit.
