The furnace air filter in your HVAC system is an important component in both the air quality in your home and the longevity and efficiency of your home’s furnace. However, this element of your Laurel home’s heating and cooling system is often forgotten or neglected.

 

In today’s blog from JDL HVAC Services in Laurel, we will discuss the multiple different facets of what your HVAC system’s air filter actually does and how often you should change it. We hope this provides you with simple, but valuable, information about your home or business heating and cooling system.

What Does An HVAC Air Filter Actually Do?

We all get the concept of what an air filter is — something that filters your air — but in what specific ways does it help your HVAC system run healthily and properly? 

 

First and foremost, the air filter is the first defense against debris that can clog or damage your heating or cooling unit, and it is also the first line of defense against allergens like dirt, pollen, and pet hair and dander.

 

When air is pulled through the filter on your furnace unit, small particles are caught in the filter, allowing for cleaner air for you and your family, as well as for netter airflow for your heating system. That translates to a higher level of efficiency when keeping your home or business comfortable, and can save you a lot of money on your utility costs over time.

The Risks Of Not Changing Your Air Filter

Increased Utility Expenses

As we just mentioned above, a dirty furnace filter can lessen the airflow to your system or even cause debris buildup within it. All of this can lead to higher than normal operating costs and energy expenditures, which can add up quickly.

Trouble Maintaining The Right Temperature

Undue stress on the fan motor due to dirt buildup in your heating unit can lead to your HVAC system struggling to successfully distribute warm air throughout your home or business. Warm and cool zones, as opposed to a uniform temperature throughout the house, are a typical symptom of this.

System Failure

Too much debris in your heater or air conditioning unit can lead to malfunctions and breakdowns that require you to perform emergency repairs, or in a worst-case situation, men you’ll need to replace the entire unit. Keeping a clean air filter is an important part of maintaining the health of your HVAC system throughout the year.

Poor Air Quality

A dirty furnace filter will catch fewer particles than a clean one. But more important than that, a dirty air filter can become home to mildew, bacteria, and even mold, which can then be drawn into your HVAC system and diffused throughout your entire home or business, increasing allergies and even causing long term health problems for your family, customers, or employees if the neglect has taken place for a long enough period of time.

Dirty Air Ducts

As your dirty, old filter continues to degrade, a greater number of particles will find their way into your heater, spelling trouble for your duct network. From here, they will be deposited into your ducting system, meaning that even when you finally do change your filter, your HVAC system will still be blowing dirty air into your home until you also pay to have a professional air duct cleaning service performed.

When Do I Change My Air Filter?

Different types of heating and cooling systems require a different frequency of filter changes. Additionally, the quality of the filter that you purchase can make a difference in how it long will last. Many Americans change their filters twice per year. Once before they turn on the heat in the fall and once again before they turn on the air conditioning in the spring or summer. In reality, most air filters should be changed every 60 days, or more often than that if a low-quality filter is being used.
