3 Signs That It Is Time To Change Your Air Filters

Posted on

Nearly every person has an air conditioning system in his or her home. They are by far the best way to keep a constant and comfortable temperature in your house. The AC unit should work well for years if it is properly cared for. One of the things you should be doing often is changing out the air filter. Here are some signs that your air filter is dirty and needs to be changed.

1. Poor Air Quality

The air filter is responsible for keeping dirt and dust out of your air supply. When the air conditioner sucks in and blows out air, the filter acts as a barrier between the system and the outside air to make sure that all air that passes through is clean. Over time the filter will catch more and more dirt and dust, until the filter is no longer able to do its job correctly, since it will be so dirty. If you are not checking the filter often, you may not immediately notice that it needs to be changed, but you will start to notice a difference in your air quality. Your house will become dustier, the people in your home may start to show allergy symptoms like sneezing, itchy eyes, and trouble breathing. This is one major sign that your filters need to be changed.

2. Low Air Pressure

When your air conditioner is working properly it should be blowing air nice and hard throughout the house. As the filter becomes dirtier, it will become more difficult for the air to pass through. This will translate into your vents not having enough air pressure. You may even think that the AC isn't working and wonder if the entire unit needs to be repaired. In most cases, a simple changing of the air filters will correct the problem.

3. You Haven't Changed It In Months

Ideally you should be changing your air filters every couple of months. If it has been a while since you changed the filters, especially if it has been over a year, you should definitely change it. It should also be noted that if you live in an area that has a lot of construction going on, or if you don't have a lot of neighbors and your house has lots of dust around, you will need to change the filter even more often.

Luckily, air filters are inexpensive and simple to buy, so there is no reason to have them on hand and be changing them often. For more information on air conditioning maintenance, contact a company like Kassel Appliance & AC Repair.
