4 Spooky Things Inside Your HVAC System


Halloween is coming up soon and bringing ghosts, ghouls, spiders, bats, and witches with it. But some of the scariest creatures of fall are the ones lurking inside your HVAC system!

At On Time Home Services, we recommend annual fall maintenance and regular air duct cleaning to keep your HVAC system efficient and your indoor air quality clean. Here are four spooky things inside your HVAC system that will show you what we mean.


If you’ve ever taken a closer look at the vents around your house, the fact that dust collects inside your air ducts is probably no surprise. Dust particles from inside your home are sucked into your HVAC system daily, and they are usually either trapped in your air filter or they settle in your ducts.

If your HVAC system becomes too clogged with dust, it can find its way back into your air and eventually settle on your furniture. To combat dust inside your HVAC, change your air filter at least once every 90 days. If you have noticed your air ducts becoming especially dusty, schedule professional air duct cleaning services or try DIY air duct cleaning for a temporary fix.


For anyone with allergy symptoms, pollen truly is the stuff of nightmares. Pollen particles attach themselves to your hair and clothes outside and then end up floating in the air inside your home. They will eventually be sucked inside of your HVAC system and collect in your air ducts with their buddies, the dust particles.

To help stop pollen in its tracks before it can reach your nostrils again, consider investing in a stronger air filter. Most homes have standard disposable fiberglass filters, which trap most unwanted particles before they can enter your indoor air.

But paper or polyester disposable filters can trap even more and even tinier particles to improve your indoor air quality. They are more expensive than their fiberglass counterparts, but for anyone with fall outdoor allergies, the difference will be worth it.

Airborne Bacteria

Another creepy inhabitant of your HVAC system is airborne bacteria. Airborne bacteria are everywhere, and it can make you sick when it comes into contact with your skin or when you breathe it into your lungs. The airborne particles are so microscopic that it is hard for traditional air filters to keep them out of your home.

One of the most effective ways to combat airborne pathogens is with an air purification system. Air purifiers destroy airborne bacteria that flows inside your HVAC system so that it never reaches your home and disrupts your indoor air quality.

Some popular air purifiers use ultraviolet (UV) light rays to “zap” the bacteria inside your HVAC system, while others use extreme heat. Our experts at On Time Home Services can help recommend the best purification system for your unique needs.


The outdoor unit of your HVAC system is especially vulnerable during the fall season. Leaves, twigs, acorns, and other debris have a tendency to end up inside your unit unless you are vigilant about regularly clearing away debris.

If too much debris builds up inside your HVAC unit, it can drastically affect its performance and efficiency. To ensure your system is operating efficiently and debris-free, we recommend scheduling fall HVAC maintenance.
