Why Your HVAC Filter Needs to Be Replaced

HVAC systems rarely need much maintenance on your part. They’re designed to be user-friendly. With a touch of the thermostat, you can direct warm or cool air into your home as soon as you need it. Any other maintenance or repairs require air conditioning repair service in Magnolia, TX.


But if there’s any maintenance related to your HVAC systems that you have to monitor, it’s cleaning and replacing air filters. Why is this so important? Why do most people feel the need to do this on a monthly basis, on average? Sure, any heating and air conditioning contractor would recommend that you do so, but have you ever wondered what effect this actually has on your HVAC systems? The answers to these questions are below.

What Are Filters For?

Air filters are designed to filter the air that passes through your HVAC appliances. They can be located in a heating or cooling appliance itself or indoors just inside the return air vent. The return air vent directs indoor air back through a series of ducts and into your appliances to be heated or cooled again. The filter is in place to keep dirt, pollen, dust, pet dander, and other airborne pollutants out of the HVAC system. They’re designed to be either disposable or easy to clean so they can continue to catch pollutants in their small fibers.

Healthy Air

It’s easy to see why catching airborne pollutants is such a pressing issue. As air cycles through your home, it can continue to collect more and more pollutants, eventually making the air in your home smell unpleasant. If you or a family member suffer from allergies, asthma, or other respiratory issues, keeping your indoor air clean is a health issue. And sadly, air filters only have a certain capacity for catching pollutants. The dirtier your air filters get, the less capable they are of actually cleaning the air. Air contractors recommend that you clean or replace your filters--depending on the type--at least once a month to help monitor indoor air quality and maintain good respiratory health.

Protect Your Heating and AC Appliances

Heating and AC appliances are among the most vital--and costly--appliances in your home. Heating and air conditioning installers recommend several methods to prolong each appliance’s lifespan. One of the most important tasks is to change your filters on a regular basis. Dirty air filters that become clogged with pollutants can start to leak them into your AC or heating units. They may also block appropriate airflow. Both of these issues can force your appliances to work harder to condition your air, straining until they eventually overheat and break down.

Save Money

When your AC and heating appliances have to work harder, they consume more energy. Heating and cooling systems are some of the most expensive to run, so the harder these appliances work, the more expensive your monthly utility costs will be. Change your filters often to improve efficiency and reduce costs. And that’s not the only way changing your filters regularly saves you money. The better you can prolong each appliance’s lifespan, the fewer repair services you’ll need to hire. Also, your up-front investment in new appliances will last longer.
