<h1>Changing HVAC Filters</h1>
<p>This playbook provides step-by-step instructions for locating, evaluating, and replacing air filters in an HVAC system. This is to ensure the maintenance of air quality and the efficiency of the system.</p>

<h3>Step 1: Safety First</h3>
<p>Turn off the HVAC system before attempting to locate or replace the air filters to prevent any risk of injury or system damage.</p>

<h3>Step 2: Locate Filter</h3>
<p>Find the air filter enclosure on your HVAC system. It's typically located in the return air duct or blower compartment before the air handler.</p>

<h3>Step 3: Examine Filter</h3>
<p>Remove the filter and check whether it's disposable or reusable. Inspect the filter for dirt, dust, and signs of wear.</p>

<h3>Step 4: Clean/Replace</h3>
<p>If the filter is reusable, clean it according to the manufacturer's instructions. If it's disposable, replace it with a new filter of the same size and rating.</p>

<h3>Step 5: Install Filter</h3>
<p>Insert the clean or new filter back into the housing, making sure it's facing in the correct direction as indicated by the airflow arrows on the frame.</p>

<h3>Step 6: Turn On System</h3>
<p>After the filter is in place, turn the HVAC system back on. Ensure there are no unusual noises that may indicate incorrect installation.</p>

<h2>General Notes</h2>

<h3>Filter Ratings</h3>
<p>Be aware of the Minimum Efficiency Reporting Value (MERV) rating when selecting a new air filter. It indicates how effectively the filter can capture pollutants.</p>

<h3>Regular Checks</h3>
<p>Check your filters every 30-90 days. Change or clean them as needed, or according to the recommendations provided by your HVAC system's manufacturer.</p>

<h3>Proper Disposal</h3>
<p>Dispose of used disposable filters properly. Do not attempt to clean and reuse a disposable filter.</p>
