If you have an HVAC system in your home, then you’ve certainly changed a filter or two. While you may know changing your filter is essential, have you ever wondered why? Many people have questions concerning their HVAC systems and how to maintain them properly. One of the most important, yet easiest ways to ensure your system operates well is to maintain a clean filter. To help you understand more about the health of your HVAC system, Furnace Doctors is here to answer a few of the most common air filtration questions.


How Often Should You Change Your Filter?

While each system has unique operating requirements, the general recommendation is to change your filter once per month during operation. If you don’t utilize your system regularly, then you may not need to change it as often. To be sure you change your filter on schedule, consider marking a day on the calendar or setting a reminder on your phone. It may seem like a trivial matter, but a dirty air filter can negatively affect the air quality inside your home.


Why Do You Need to Change Your Filter Regularly?

Many issues can result from failing to change your air filter regularly. A dirty filter not only allows particles into the air inside your home, but it can also result in the following problems:


●        Clogged system coils due to dirt buildup

●        Frozen coils as a result of low airflow

●        Increased utility bills due to poor performance

●        Allergen and dirt accumulation inside ductwork


Changing your filter is a simple process that takes only minutes. Don’t neglect the health of your family or the integrity of your system by failing to maintain a clean filter. If you do suspect that your system is performing poorly, you can schedule indoor air quality testing with a professional.


Do the Furnace and AC Use the Same Filter?

Yes. Your furnace and your air conditioning comprise your HVAC system in its entirety. If both hot and cold air travel through the same ducts in your home, then they use the same filter. You may notice them referred to as either furnace or air conditioning filters, but there is no difference. When you install the filter, it should sit in your system’s air handler, which both your heating and cooling systems share.


What Type of Filter Should You Use?

The style of filter you use depends on many factors. You’ll need to consider whether you have pets, how often you clean your home, if you smoke indoors, and if you suffer from allergies. Determining the level of air filtration you require will help you choose the appropriate filter for your system. MERV, or minimum efficiency reporting value, measures the quality of your filter. Ratings range from one to 16, and the higher the rating, the more micro-particles the filter removes. If you suffer from allergies, have pets, or have low air quality, look for a filter with a higher rating.
