Is It Time to Change Your Air Filter?

Maintaining your HVAC system is essential for keeping your home clean and comfortable. One of the most important tasks is changing the air filter regularly, but how can you tell when it’s time to do so? Here are some tips for determining when it’s time to replace your air filter.

Inspect the Filter Regularly

It’s a good idea to check your air filter at least once a month. This will help you identify if the filter is clogged with dirt, dust, and other debris that can impede airflow and reduce the efficiency of your HVAC system. If you find that the filter is dirty or clogged, then it’s time to switch it out.

Evaluate Airflow

If you notice that the air coming out of your vents isn’t as strong as usual, this could be an indication that the filter needs replacing. You can also test airflow by holding a piece of tissue paper up to one of the vents. If it moves easily, then there is good airflow; if not or only very slowly, then this means that a new air filter should be installed.

Look for Wear and Tear

If you inspect the air filter closely, you may notice signs of wear and tear such as tears in its material or dirt buildup on its edges. These are all signs that indicate that it has reached its maximum lifespan and needs replacing.

Change Every Three Months

Even if there are no visible signs indicating that an air filter needs changing, it's still recommended to replace them every three months. This will ensure optimal performance from your HVAC system, reduce allergens in your home, and improve indoor air quality.

Choose Wisely

When selecting an air filter for your HVAC system, make sure to pick one specifically designed for this purpose. This will guarantee proper fitment and superior performance.


In conclusion, checking on your air filters regularly, testing airflow, looking out for wear and tear, changing them every three months, and choosing wisely are all important steps towards ensuring optimal performance from your HVAC system.
