How Fog Machines Can Affect Your HVAC Efficiency

How Fog Machines Can Affect Your HVAC EfficiencyOne of the most popular ways to give your home a creepy, spooky atmosphere this Halloween is with a fog machine. But what kind of impact can that fog machine have on your home’s air, or your HVAC efficiency? Let’s take a look.

Fog and Indoor Air Quality

For the most part, a fog machine won’t have too much of an effect on your actual HVAC system, particularly if you’re only running it for a few hours. However, it can be detrimental to your indoor air quality, particularly if anyone in your home is asthmatic. Some of the chemicals used in water-based fog machines can exacerbate asthma symptoms and cause attacks.

Even if you don’t have asthma, being in close proximity with a fog machine for a long period of time can cause bronchitis and other respiratory problems, along with headaches and dizziness. If you’re going to use a fog machine, choose one that uses liquid air, rather than water or dry ice. Those are the safest, as they don’t reduce the oxygen levels in the air. And keep your HVAC system running to make sure the air in your home continues to circulate.

Other Halloween HVAC Considerations

There are other factors besides fog machines that can affect your HVAC efficiency this Halloween. Be careful when putting up decorations not to hang anything over or near any of your air vents or registers. Large obstructions can restrict airflow, forcing your system to work harder and use more energy. Smaller items, meanwhile, can actually find their way into your ductwork and eventually to the unit itself, where they could damage the system’s inner workings or cause it to overheat.

And if you’re having a party, extra people in the house will make things warmer, and if you’re cooking or baking, that can heat things up as well. Be sure to turn the thermostat down a few degrees to keep everyone comfortable.
