Spooky and Scary HVAC Mysteries, Solved!

October 12, 2021

The spookiest month of the year is here, and we thought we’d share some of our most frightful HVAC stories. As Los Angeles heating and cooling professionals, we see our share of “paranormal activity” with HVAC systems. And while our team may not be ghost busters, we’ve tracked down the cause of these happenings. So read on, dear visitor, there’s no need for a garlic necklace. Our team here at Brody Pennell knows exactly how to avoid these hauntings!

Air Conditioner Frozen in Fear

On another gorgeous Los Angeles afternoon, you notice a sight often unseen in Southern California… ice… on your AC unit. A chill runs down your spine, causing goosebumps to rise on your forearms. How is it possible for an air conditioning unit to freeze over, even with our mild LA temperatures? 

Allow us to break the spell. A frozen AC unit or coil is not the work of a ghostly creature; it’s typically either a refrigerant leak or an airflow problem. If your AC system doesn’t have enough refrigerant, the pressure inside the pipes changes, causing the coils to freeze up. 

The other issue is an airflow problem. Air conditioners need a clear airflow path. So if you have witch’s hats and brooms blocking the vents to your system, that could be the cause. If you need any help, contact our team for AC repair and service.

Screeching and Squealing 

Recently, a customer called us complaining about whining and howling coming from their attic. The man said the ghost hunters who came last week were unsuccessful in detecting any paranormal phenomena. The Brody Pennell team arrived on the scene and discovered the high-pitched crying belonged to… the heater

Screeching noises from the attic COULD be ghosts, but it’s more likely that a damaged fan belt or another component that requires replacement. Squealing sounds like this are a sign that your unit is dying for a repair… or maybe it’s time to put your aging system to rest and replace it. Contact our team for an HVAC professional’s opinion

Hovering Dust Bunnies

Have you ever been alone in a room and had an unsettled feeling? And out of the corner of your eye, you think you see someone. Maybe it was a shadow. Or a reflection in the window. Yes, that’s it. 

Or perhaps it’s the most terrifying of all. 

Dust and pollen floating in the air of your home. 

There will always be dust in your home, but when the particles are large enough that they are visible to the eye, the air is not being filtered completely. And dust isn’t the only villain; there are invisible particles (such as bacteria and viruses) in your home as well. And if you do nothing about it, they just keep recirculating through your HVAC. 

It’s time to take control of your IAQ (indoor air quality). First, replace the air filter in your furnace. If you still see mysterious hovering orbs after 48 hours, it may be time to investigate an in-ductwork air purifier or UV sterilizer to eliminate the problem.
