Why Changing Air Filters Is Crucial

Clean air filters are a major factor in a well-functioning HVAC system. They're also your primary line of defense against dust and bacteria, mold and pet dander, and other particulates that can circulate throughout your home.

Amidst poor air quality and winter pollution in Phoenix, clean air filters are particularly crucial for:

  • People with asthma or allergies. Respiratory trouble occurs if someone with these conditions encounters significant quantities of dust mites, mold spores, pet dander, or pollen in your home's atmosphere.
  • Pet owners. The more fur and hair your pet sheds, the likelier they are to contribute to respiratory issues, making it a good idea for pet owners to change their filters more often.
  • Families with young children. Small children and infants are extra-sensitive to poor air quality, so clean air is especially important for any household with children under five years old.

Aside from health concerns, having clean air filters will lengthen the lifespan of HVAC systems, avert breakdowns, and ensure an efficient operation that keeps your energy bills down.

When to Change Your AC Filter

Given the hot and arid desert conditions where dust and fine particles are prevalent, Phoenix homeowners need to be proactive about changing their AC filters. We recommend checking your AC filter every month and replacing it every 1-2 months.

This is especially important during peak usage months like summer when your AC system is working harder to keep your home cool. Additionally, if you have pets, live near construction sites, or experience higher levels of indoor pollutants, more frequent filter changes may be necessary.

When to Change Your Furnace Filter

It's generally recommended to change your furnace filter at least once every three months. More frequent replacements will likely be needed in a household whose members suffer from asthma or allergies or in any home where pets are present.

Just like with an AC filter, you should be able to tell if your furnace filter is ready for a change with a visual inspection or by checking the airflow: changes in color or limitations in the outward flow of air are indicators that your filter is dirty. Indirect signals like rising energy bills, an accelerated dust buildup in your home, or strange smells are also telltale signs.

When to Change Your Heat Pump Filter

You should replace your heat pump’s air filter twice a year, at least. Again, this will depend on the details of who lives in your home and what their specific needs are.

One of the unmistakable signs that you need to change out your heat pump filter is when you notice a reduction in its ability to effectively warm or cool the house. This is typically caused by the filter becoming clogged with debris that constricts air circulation.

Benefits of HVAC Maintenance

Regular HVAC maintenance from trained professionals is one of the best and easiest ways to protect your HVAC system from unnecessary strain caused by clogged air filters. When an experienced technician has a chance to inspect, clean, and optimize your HVAC system, they can let you know if and when replacement parts– including air filter replacements– are necessary. Plus, you’ll have peace of mind knowing your warranty stays valid (most manufacturers require annual tune-ups to keep warranties intact).

To make annual maintenance even easier, many HVAC companies offer maintenance plans that provide yearly tune-ups and automated reminders. Whenever you’re due for a tune-up, you’ll get a friendly text or email letting you know.
