Despite being one of the most important parts of a HVAC system, the air filter is also one of the most ignored parts by many homeowners. Many homeowners ignore their air filters until they cause serious repair problems. According to HVAC experts, you should change your air filters at least every three months.

Most people think replacing their filters should be done solely by HVAC experts – when you can in fact do it yourself in under a minute. When your filters are not replaced, they may get clogged by dirt – and this could cause your HVAC system to overwork, thus skyrocketing your energy bills. Here’s how to install an air filter in under a minute:

How to Install air filters in house (step by step)

If you don’t know where your filter is located, use the system's manual to locate it. You may also require a ladder to reach the air filter. Once located, follow the below home air filter Installation steps:

Step 1:

First, remove the plastic cover so as to access the filter below. While the location of the filter varies in different HVAC systems, you'll be able to locate it if you see a long, thin opening with a plastic removable cover.

Step 2:

Ensure you turn off your system so as to avoid electrocution or harming the machinery. This will also prevent dust and particles from sneaking into the system while the air filter is removed.

Step 3:

Once that’s done, remove the old air filter. You should be able to slide out the filter easily. Also be careful when removing the old filter since it could be covered in dust and dirt that could cause some serious mess – if not handled well.

Step 4:

Once the old filter is removed, insert the new filter by sliding it into the empty slot. This should happen with little to no resistance. The filter normally has an arrow on its side that shows the airflow direction. Ensure this arrow is pointing in the same direction as the old filter you previously removed. Ensure the arrow points towards the duct and the system’s blower.

Step 5:

Inspect the filter for any gaps around it. If you see any gaps around the filter, remove it and temporarily put back the old filter. The gaps could be caused by a wrong filter size. If this is the case, ensure you inquire for the right one and buy it.

Step 6:

Ensure you clean off any dirt or dust that was left when you removed the old filter – and turn the system back on. Also, ensure you note down the date when you replaced the air filter. This will help you know when next to replace it.
