One of the most important things that homeowners must do is take good care of their HVAC system by simply changing the air filter regularly. This keeps everything working smoothly and also helps to maintain energy bills low. However, failure to replace the air filter for several months can lead to significant increases in energy prices and other maintenance costs, as well as poor health for the people who live in their homes.

Notice These Signs in Your Filter?

Here are some signs that will help you know your filter needs to be changed:

  • Accumulation of Dust 

When an air filter becomes clogged, it often begins to release dirt and contaminants into the system, which can eventually be expelled through the vents. Dirt and dust around the vents do not necessarily mean that the filter needs to be replaced-it may also indicate that the duct is clogged. But if you notice this problem consistently, then checking the filters is worthwhile.

  • Air isn’t Cold Enough 

If the air conditioner is not cooling the room properly or giving warm air, it is important to check the air filter. A dirty air filter does not allow its refreshing cold air to pass properly, keeping your room warm. So if you notice such a problem with the air filter, an experienced HVAC service technician should investigate it and perform the necessary AC Repair in Los Angeles.

  • Odd Noises 

Air conditioners should not make much noise when they are on. If you notice your device making noise even though it was quiet before, the air filter may be clogged. In this case, the device will not be able to push the air evenly through the filter. Air is blocked in the filter area rather than passing through the unit into the room. So, you need to contact an agency to check your filters. 

  • Poor Air Quality 

The frequency with which the air filter is replaced also affects the air quality inside and outside the house. If the air quality inside and outside the house is poor, the air filter should be replaced more often. No doubt replacing the filter will improve the air quality of the house.

Now that you know exactly how important it is to replace the air filter, you may be sitting here and wondering how often you need to replace it. In general, it is important to replace the air filter every two months to make sure it is currently operating at its best performance. Or, if you see any of the above signs, consider changing them.
