A new air filter will help to remove allergens and other particles from the air, making it easier to breathe and reducing symptoms.
3. Higher Energy Bills
If your energy bills suddenly start to creep up, it could be because your air filter is full of dirt and debris and is no longer able to trap these particles efficiently. This means that your HVAC system has to work harder to circulate air, which uses more energy and drives up your energy bill. If you notice a sharp increase in your energy bills, it’s a good idea to check your air filter and replace it if necessary.
4. Strange Noises
If you’re hearing new or unusual sounds, it could be a sign that your filter is dirty and needs to be replaced. Some common noises that may indicate a dirty air filter include rattling, squealing, or clicking. If you’re hearing any of these sounds, it’s best to have a professional take a look at your unit to determine if a new filter is needed.
5. Temperature Regulation
If you notice your home isn’t maintaining a comfortable temperature, it’s probably time to replace your HVAC air filter. If your home is suddenly feeling stuffy and hot, or cool and drafty, it’s likely that your air filter is the culprit. A dirty air filter will block airflow and make it difficult for your HVAC system to effectively heat or cool your home.
Understanding How Often You Should Replace Air Filter
