Clogged AC Vent

An Air Conditioning unit consists of many parts. The vent is a crucial part that determines the quality of air. The air vent is where the refrigerant passes from the AC into your house. Hence, an obstructed Clogged AC Vent can be a real hassle for a homeowner, but it doesn’t have to be that way.

Since your AC plays a vital role in your home’s daily comfort, you should resolve a clogged AC vent as soon as possible.

 Signs of clogged AC Vent pipe

Knowing when you are dealing with a clogged AC vent is an integral part of the process. However, where you are not so sure of this, you can contact experienced HVAC companies like Direct AC to help look into this and let you know what is wrong

The following are other evidence of a clogged AC:

  •     AC not cooling

When you start to deal with issues like AC not cooling enough or is not cooling as fast as expected. It may be that the vent is clogged and needs some cleaning. The air circulates into your house through the air vent, so when it is clogged, it means air is somewhat trapped in the system instead of being circulated.

  •     The indoor air is dusty

If the air indoor is getting excessively dirty, it is a sign of a clogged or dirty air vent. When the air in the AC is dusty, and the air filter cannot perform its duty, the air vent also gets dirty. It should be noted that the air vent does not really filter the air, so you will still be dealing with dust in the house.

  •     AC vent does not pass the white sheet test

Whenever you want to know if the air vent is clogged or dirty, just put a white sheet on the vent and wait for some minutes. If you remove the white sheet and it is dirty, the air vent needs cleaning.

 Step to step guide on how to unclog your AC vent

Step 1: Turn off the AC

The first step to unclog your AC vent pipe is to ensure that you are already off the AC. Working with the unit on can be very dangerous, and you have no reason to try that. If you want to do this when there is an electricity outage, it is still advisable to switch off the unit before you start.

Step 2: Remove the vent

Once you have put off the Ac, start unclogging by removing the AC vent. This can be done easily using your screwdriver. Remove the vent and set it aside.

Step 3: Unclog the vent

When the vent is clogged, it means you are dealing with a lot of dirt, which can only be resolved by doing a thorough cleaning. First, take your vacuum to dust off the vent. This works to remove any debris and dust clogging the vent. Ensure that you do this thoroughly for the best result. I recommend doing this inside a big carton, so you do not have to do a lot of cleaning to do after this.

Step 4: Prepare to wash

After cleaning with a vacuum, it is time to clean with water. Set aside a bucket add water and soap inside. Now take the vent to a sink or bathroom for washing. You can use a bathtub or big bucket for similar results. The goal is to ensure that you have enough space for washing without creating a big mess for you.

Step 5: Soak the vent for about 15 minutes

Once you’ve prepared the water, soak the vent inside it for fifteen minutes and clean it carefully using a brush. This will help remove the remaining dust, debris, and grease that let the vent get dirty faster. 

Step 6: Dry the vent

Get a towel and dry the vent. First, ensure that it is thoroughly dry. I recommend leaving for about 20 minutes after you’ve dried it with a towel to prevent it from rusting.

Step 7: Return the vent

Finish up by returning the vent. Fix back using your screwdriver, and you are ready to enjoy the refreshed air.

Repeat the process above

Repeat steps 1-7 every month to ensure you stay on top of any build-up and avoid problems with your AC usage.

It shouldn’t take long to look for and clear a vent. Even in the comfort of your own home, you can keep your AC vent clean and extra clear by keeping an eye out for these simple signs and following an easy cleaning guide.
