HVAC contractors recommend frequently changing HVAC filters, and consider it one of the easiest and most effective maintenance tasks you can do. It may seem like a minor task, but this piece is integral to the heating and air conditioning process. Whether it’s a disposable or washable filter, in many ways, it’s the first line of defense for your unit and system as a whole. To better understand why it should be changed regularly, here’s what you need to know. 

Why HVAC Filters Must Be Replaced

1. Air Quality

As your heater or air conditioner runs, it pushes around dust, dander, pollen, and anything else circulating in the air. The filter is designed to catch these particulates. When it gets clogged, there’s nowhere for these particles to go. Replacing it is the best way to prevent them from floating around in the air. How often to change it depends on various factors like respiratory issues, if you have pets, and how many people are in your household. This frequency can vary from monthly to seasonally. If you’re unsure how often you should be replacing it, consult an HVAC contractor. 

2. Financial Savings

Clogged filters diminish airflow, which ultimately hampers its efficiency. When it’s clogged, your unit must work more frequently to thoroughly transfer heated or cooled air throughout your home. The more this happens, the higher your utility bills will be. If your bills have gone up and you haven’t intentionally increased your usage, try changing the filter. 

3. Unit Longevity

Finally, HVAC contractors also recommend changing the filter because it ensures it runs smoothly for as long as possible. Another side effect of diminished airflow is that it makes it difficult for the unit to cool down. An overheated unit can lead to a variety of problems like a damaged thermostat and cracked components. If you want to avoid needing these repairs, replace the filter.
