6 Spooky Things Lurking In Your HVAC System

October 11, 2017

As you prepare for another fun Halloween with your friends and family, you’re probably focused on finding a frightfully fun costume to wear and making festive treats with your kids. What you don’t often think about are the spooky things lurking in your HVAC system. Consider what could be hiding just out of sight behind your air registers. Then, use tips from Rick’s Heating & Cooling to banish them once and for all!


As the temperature drops outside, you might start noticing uninvited guests in your home. Of course, live spiders, crickets, and centipedes were probably not what you had in mind for Halloween decorations! Even if you don’t see them, these creepy-crawlies could end up in your ductwork, along with birds and rodents. Schedule ductwork cleaning if you suspect animals have made your air vents their new home.

Cobwebs & Dust

A large amount of dust travels through your ductwork every day. Cobwebs form and dust accumulates on the metal walls. Soon, it resembles a haunted house in there! One way to reduce dust buildup in your HVAC system is to replace the filter every one to three months or as recommended by the manufacturer.

Slimy Mold

What’s dark, slightly damp, and has ample food sources for mold to grow? Unfortunately, the answer is your ductwork. The metal ducts running behind your walls and ceilings are some of the creepiest places in your home. If the dust and other debris accumulated here become slightly moist, the ductwork quickly becomes a breeding ground for mold. This could be detrimental to your indoor air quality, so have your ducts inspected if it’s been awhile since you had them cleaned.

Microscopic Nasties

The germs that make you sneeze, sniff, cough, and blow your nose could be hiding in your HVAC system. Don’t let these bacteria and viruses ruin your plans for Halloween! Instead, have a HEPA air cleaner installed to remove microscopic nasties from the air you breathe. This way, candy will be the only thing that spreads from person to person on Halloween night.

Foul Odors

If you turn on your furnace on a dark and stormy night only to be greeted with musty air fit for a mummy’s tomb, it’s safe to assume something is wrong. Try replacing the filter, which may have mold growing on it. If you notice a rotten egg smell, oily aroma, rotting stench, or other foul odor, call a repair technician right away to diagnose the problem and come up with a solution.

Things That Go Bump in the Night

If your furnace rattles, squeals, or booms, you might think a poltergeist is living in your HVAC system! While the source of these bumps in the night isn’t quite this frightening, it’s still important to have the problem inspected before it gets any worse. After all, depending on what’s wrong, ignoring the racket could put your family in harm’s way. This is why you should always take odd furnace noises seriously.
