Here’s What Happens If You Don’t Change Air Filter In Your House

Having an HVAC system is mandatory if you want to feel comfortable during the hottest months of the year. Once you get your appliance, it is crucial to schedule regular visits to prevent any issues. However, there is a part of the maintenance you also need to take care of. Changing your air filter is a simple task you can do alone. The best part is that this will help you expand the lifespan of your air conditioner.

Today, there are different HVAC systems available in the market, but you shouldn’t choose just any model. There are several factors you’ll need to consider, such as the size of your property and how many people are living in your house. Plus, you should think about the types of filters that are compatible with the appliance and how often you’ll need to change them. 

Changing your air filter is a crucial part of the maintenance of your HVAC system. In case you forget to do it, your device could start malfunctioning. But before we talk about this, let’s look at the types of filters you might have at home. 

Types of HVAC air filters

The first thing you need to understand is that not all filters work the same way. While some of them might focus on eliminating bacteria, others keep dust out of your home. That’s why when you choose the air filter for your home, you need to be aware of the different kinds and their characteristics.

  • HEPA filter

If your kids have any allergies or respiratory problems, then this might be the perfect air filter for your home. A HEPA filter will efficiently remove any airborne particles and pollutants such as mold spores and pet dander. This means you’ll have clean air all year long. Keep in mind that, due to their characteristics, these filters could be more expensive. 

  • UV filter

A UV filter, as its name states, uses ultraviolet technology to eliminate any viruses or bacteria from your airflow. Even though this sounds great, you should keep in mind that this filter has its limits. For instance, it won’t be able to get rid of common pollutants such as dust.

  • Electrostatic filters

This is usually the type of filter most homeowners have. Think about an electrostatic filter as a magnet that catches all airborne particles, including dust. Today, you can find reusable or disposable filters. They both work the same, but the only thing that changes is the kind of maintenance it needs. 

  • Washable filters

In case you are looking for an environmentally friendly alternative, a washable filter will be perfect for your home. You can use this product several times, but you’ll have to clean it regularly. The only downside is that this filter is more expensive compared to the other ones we have mentioned. However, in the long run, it will be more cost-effective. 

Because air filters are an essential part of your HVAC system, when you forget to change them, this can cause critical issues in your device. Sometimes, you can fix it by purchasing another filter. But, if nothing changes, you’ll have to call a professional such as Anderson Air, one of the top HVAC providers. 

What happens if you forget to change the air filter?

Even though some homeowners think you can wait up to a year to change your filter, they are wrong. As a rule of thumb, you’ll need to replace this part of your system every month. However, this could vary depending on the type of filter you have. 

But what happens if you don’t change this air filter?

  1. Wear and tear of your unit

After some time, your air filter might get clogged. This means it will be more difficult for the air to get through. In this case, your HVAC will have to work harder to push air through your home. Your unit will also be using more power, which could increase your energy bills. Plus, in the long run, it could damage your air conditioner. 

  1. Ductwork buildup

Once your air filter is clogged, then all the contaminants and particles such as dust will start creating a buildup in your ductwork. If all these components enter your HVAC system, it could damage your fan motor. In this case, you’ll have no other option but to call a professional and pay for the repairs. 

  1. Bad indoor air quality

The reason why all HVAC systems need an air filter is that this helps homeowners increase their indoor quality. But, if your filter gets clogged, then it won’t be able to remove any airborne particles. This could worsen any respiratory symptoms if there is anyone in your home who suffers from asthma. 

  1. Discomfort

An HVAC unit is what allows us to regulate the temperature inside our home and create a comfortable environment. But, if the air filter is not working, then the air conditioner won’t be able to reach the desired temperature. At home, this means it could be difficult to sleep or even stay inside your house. 

How can I change the air filter?

To avoid all the possible consequences you could suffer if you don’t change the filter. You need to learn how to do this part of the mandatory maintenance for your unit. The good thing is that you won’t need to call a professional, and it will only take a few minutes. 

If you have a disposable filter, the first thing you need to do is check the correct size for the replacement. In case you forgot, turn off your system and open it to see which filter you need to purchase. Once you have the new air filter, follow the same steps, then remove the old filter and wipe the surroundings with a cloth. Finally, put the new filter inside following the arrows. 

In case you have a reusable filter, the only thing that changes is that you’ll have to take it out and clean it. You can do this by using a hose. Then, let it dry and insert it again into your HVAC system.
