Air filters are an essential part of any HVAC system. They clean the indoor air of dust, pollen, bacteria, and other contaminants before it enters your home or workplace. Air filters trap these contaminants and prevent them from circulating throughout your home or office. Unfortunately, air filters also have a tendency to get dirty and clogged. If you notice that your HVAC system’s filters are dirty, or if they’re making a strange sound when you turn on your air conditioner or fan, read on for some helpful advice on how to troubleshoot your air filter problems.

Check the filter’s condition

The first step in troubleshooting air filter problems is to check the filter’s condition. Take a look at the filter and see if it’s discolored, if it’s wet, or if it’s sagging. If the filter is discolored or wet, it’s probably time for a new filter. If the filter is sagging, it’s probably time for a new HVAC system. If the filter looks clean and dry, you can move on to the next step.

Change the filter and see if that fixes the problem

If the filter is clogged and dirty, it’s likely that it’s causing problems for your HVAC system. To check if the filter is causing these problems, change it and see if the issues disappear. If the problems persist, then you’ll need to clean the filter. Changing the filter is essential so that it can trap contaminants and prevent them from entering your home or business. If the filter change doesn’t fix the problem, then you’ll need to clean the filter. Follow the instructions below for cleaning the filter.

Clean the filter with a vacuum

If the filter is clogged and dirty, you can clean it with a vacuum. Place the filter in a plastic bag and seal it. Then, attach the vacuum to the bag and turn it on. This will suck the dust and debris out of the filter and into the bag. Once the filter is clean, put it back in the HVAC system and see if that fixes the problem.

Use a hair dryer to clean the filter

If the filter is clogged and dirty, and you can’t clean it with a vacuum, you can clean it with a hair dryer. Place the filter in a plastic bag and seal it. Then, attach the hair dryer to the bag and turn it on. This will heat the filter and melt away the dust and debris, allowing you to clean it. Once the filter is clean, put it back in the HVAC system and see if that fixes the problem.

Check the filter’s flow rate

If the filter is clogged and dirty, and you can’t clean it with a vacuum, you can clean it with a hair dryer. Place the filter in a plastic bag and seal it. Then, attach the hair dryer to the bag and turn it on. This will heat the filter and melt away the dust and debris, allowing you to clean it. Once the filter is clean, put it back in the HVAC system and see if that fixes the problem. If the filter flow rate is low, you’ll need to replace it. Flow rate refers to how quickly the filter is able to trap contaminants. A low flow rate can cause your HVAC system to break down and fail. If the filter flow rate is too low, it will cause your HVAC system to break down and fail. If the filter flow rate is low, you’ll need to replace it.

You should change your air filters every 90 days. However, if you have allergies, you better change them after 45 days. It also depends on the MERV rating of the filters you are using. On average, it is highly recommended to change your air filters every 90 days. 
Yes, it does. There are many types of air filters and their performance is based on their material and most of the time their MERV rating. Choosing the best one will make a huge impact on how long your HVAC system will last.
HVAC air filters have different variations depending on their quality and sizes. Most HVAC manufacturers would recommend buying a new air filter that is compatible with HVAC. These air filters have a Minimum Efficiency Reporting Value or MERV which will tell you their overall performance in filtering contaminants in the air.
Most likely it will not filter the air properly. Dust will accumulate on your filter thus affecting some parts of your Air Conditioning unit. Aside from not being able to work properly in filtering the air, it will damage the system of your AC, because the airflow is affected.
