Don’t Let Your HVAC Filter Be Your Dirty Little Secret

At Dust Goblin, we understand. You have a lot going on in your life and your HVAC filter may not be at the top of your mind. But think about it—whenever we neglect any home maintenance, no matter how small, it can become a big and costly problem. 

The same is true for your HVAC system filters. There are, in fact, some important reasons you do not want to neglect it to the point where it becomes your dirty little secret.

What Your Filter Actually Does

One of the main reasons people forget or put off changing their air filter is not understanding what it does. According to the EPA, "The main purposes of a Heating, Ventilation, and Air-Conditioning (HVAC) system are to help maintain good indoor air quality through adequate ventilation with filtration and provide thermal comfort."  

While a high-quality filter will help to filter dust, pollen, dander, mold, and other allergens, its other duty is to keep these particles from damaging the system and causing a malfunction or breakdown.

What happens when you don't change it regularly? Nothing good.

Indoor Air Quality Decreases

The EPA also says that indoor air quality can be two to five times worse than outdoor air quality. That's pretty hard to believe, isn't it? When HVAC filters are not changed frequently enough, particles remain in the air and the indoor air quality significantly decreases.

Airflow Decreases

When filters are not changed regularly, the trapped dust and particles compact to a nearly impenetrable barrier. This decreases airflow. When the air in your home becomes stagnant, it causes other problems such as increased humidity, which can cause an increase in mold and foul odors.

Buildup on Fans, Ductwork, and System Mechanics

Once the filter has reached its capacity, it cannot block the dust from reaching and settling on fans, ductwork, and mechanical parts. All of that dust will be pushed back out into the home or settle on sensitive parts, causing system slowing or breakdown.

Heating and Cooling Takes Longer

When airflow decreases, it takes much longer to heat or cool the home. The trapped air remains around the coils longer and takes longer to move through the duct work. By the time it reaches the vents, it has had plenty of time to adjust to the ambient room temperature.

You Pay the Price But Do Not Reap the Benefits

Nobody likes paying for something and getting nothing in return but that is exactly what happens when you do not change your HVAC filter.

If you are running a system with a clogged filter, all of that conditioned air sits around the coils then moves so slowly through the filter that it is no longer the desired temperature.

According to energy.gov, heating and cooling accounts for 48% of energy costs in most homes and is the largest energy expense in most households. Even a small decrease in efficiency can end up adding up to a huge annual loss.

There Really Isn't a Good Reason to Put Off Changing Air Filters

Not that you know there is a huge cost to neglecting your air filters, you really don't have any reason put it off any longer. And the good news is that changing them is easy.

You can do it yourself, but if it has been a while it may be helpful to have an expert come in and inspect the system to ensure that there is no build-up in the system.

HVAC experts suggest the frequency for changing filters is between 30 days to 6 months. Simply determine the air filter size, and then choose a high-quality filter like Dust Goblin for best results!
