Why is my air conditioner sucking in the filter? What kind filter should I use for my central ac unit?


Dadan replies:

Ok … Here is a question?

Is the filter dirty – if it not


There are two other reasons:

Not Correct Filter

We could have the wrong ac filter for our central ac unit. Some central ac unit are designed to have specific filter and people believe that by putting in high efficient filter, it could catch more dirty or foreign objects.

This is not the case, this have opposite effect. A high efficient filter will act as a restriction. This is the same thing as having a dirty filter. If the indoor blower couldn’t suck the air through the filter, it would suck the entire filter in (if the blower is strong enough).

There are people, who decided to go with the cheapest filter, this filter tends to have weak frame. I have seen it being suck into the duct works.

Bottom line:

The ac filter needs to be the right filter. If we can’t determine the correct filter, ask your tech. Or, we could buy the filter that is in between the price, not to cheap or expensive just in the middle.

Motor Speed

In some situation, some people will put in the wrong speed for that specific unit. No, I haven’t seen motor increase the speed by itself. So, it has to be outside source.

Could the air conditioner filters facing the wrong way cause it?

Huhh … I’m not sure about that.

Ac filter is designed to allow air to flow in one direction (there should be arrow label on the frame of the filter). One side of the ac filter is better than the other.

If we were to reverse the filter direction could that cause the filter to pull in? No … If I'm wrong, correct me. If we put the ac filter in the wrong side, it not effect at catch particle. That pretty much it.

There are many problems in a house, sometimes your AC device may damage or other times your kitchen appliances will damage. But you shouldn't neglect these facts and try to repair all the house gadgets and appliances on time or resort to a specialist to do so. For example, the heating and cooling Denver service will provide for you a natural or a LP gas-powered water heater for residential use. Therefore, if you consider that it is the time to change the boiler, this is the company from where you should order it.

by: Anonymous

Some homeowners admitted that they can not live without an air conditioning in their home. The main use of it is to maintain an optimal temperature inside the house when outside is very hot, but also to dry the air or to humidify the interior space. Also, these devices are useful if someone doesn't want to have mold, because he can control the moisture level inside the house. But if he has already mold, he should resort to a reputed company, like mold removal Las Vegas service, to get rid of mold.

I had my annual maintainence performed and a new filter put in by the tech. When system on and running, it is getting sucked and makes an annoying noise. Correct size new filter put in by a pro. So what could be causing this? We did have a squirrel in attic could it of caused damage to a line?

Filter getting sucked in
by: Kay

If you have the filter in incorrectly, this will happen. A good quality filter with wire mesh should be used and installed properly. when inserted, the wire mesh should be facing the inside of the duct and not be visible from the outside.

Ac Filter Suck In
by: Ur Neighbor Tech

You probably have dirty ac filters or someone could have increased the blower speed. But, I doubt that could cause it. I’m presuming that you have the correct ac filters for your central air conditioner unit.
