Air Duct Cleaning questions, answered by experts

Yes, rust in ductwork is bad if it’s left untreated. Mild rust can be removed before it causes any significant damage. However, if you ignore rust, it can affect the structural integrity of the ductwork, and you’ll eventually need to replace it entirely. In addition, rust-causing moisture in ducts can also cause mold growth.

Yes, unfortunately, scorpions do come up through air vents on occasion if they’re not properly sealed. These pests are excellent at finding small openings and may use vents as a pathway to cooler areas inside, especially during hot weather. To prevent this, inspect your vents, seal any gaps, and install fine mesh screens where necessary.

You can partially clean the ductwork yourself using a dryer vent brush and a high-powered vacuum cleaner. However, without the proper equipment, you won’t be able to reach deep inside the ductwork for a thorough cleaning. A professional air duct cleaning company can remove all the dust and debris from your ductwork and address rust before it becomes a more significant issue.

While most air conditioners can last between 10 and 20 years, they will only last this long (or longer) if properly taken care of. Routine maintenance and inspections help keep your AC unit running in tip-top shape but understanding what factors will decrease its lifespan will also help keep your unit running cool.

Some things that shorten your AC’s lifespan include:

Extreme outdoor conditions, like high humidity or extensive salt spray
Improper installation
Extended run times, either by the unit being too small or the thermostat setting too low
Not performing required maintenance

Seeing black dots around the air vents is alarming, but don’t worry. It’s probably just a build-up of soot and darkened dust. Soot is just a byproduct of burning organic materials, so it tends to form in the winter months.
