How Often Should You Change Air Filters During an HVAC Tune Up?

If you own an HVAC system, manage a rental property, or are a tenant in a home with an HVAC system, you want to make sure it's properly maintained. Regular maintenance can help reduce system wear and tear and decrease the number of repairs it will need over its lifespan. One of the most basic forms of maintenance is to change the air filter. So how often should you change the air filter? For basic 1 to 3 air filters, brands usually recommend changing them every 30 to 90 days.

If any family member has mild to moderate allergies, you can add a better air filter or change it more frequently. Different types of air conditioner or furnace filters have different specifications about when they need to be replaced. Fibreglass filters are cheaper; however, they will need to be replaced more often (usually every 30 days). Pleated air filters are more expensive than fiberglass filters and are made with higher quality materials.

These filters can last 3 to 6 months, depending on several factors. The general recommendation for how often air filters should be changed can range from every 30 days to every year. Two of the factors that determine the lifespan of a filter are the type and quality of the filter being used. Ultimately, the decision about how often you should check, clean, or replace the air filter in your HVAC system is up to you. As an expert in HVAC systems, I recommend that you check your air filter at least once a month and replace it when necessary.

This will ensure that your system is running efficiently and that your family is breathing clean air. If you have any family members with allergies or asthma, I suggest changing your air filter more frequently or upgrading to a higher quality filter. When replacing your air filter, make sure you choose one that is compatible with your HVAC system. The size and type of filter should be clearly marked on the side of the existing filter. If you're unsure which type of filter to buy, consult your local HVAC technician for advice. Changing your air filter regularly is an important part of maintaining your HVAC system.

It's also important to have regular tune-ups performed by a professional technician to ensure that your system is running efficiently and safely.
