What Is Negative Pressure Duct Cleaning? And Why It Matters

If you look around your home or building, you can see dust on surfaces and vents, but not what is happening deep inside the ductwork.

You usually notice it on the first really hot or cold day.

Duct Sealing vs. Duct Cleaning: Which One Does Your Home Need?

Dust that won’t quit, rooms that never feel quite right, or mystery odors every time the HVAC system starts, when your ducts are involved, it’s easy to assume they “just need a good cleaning.” Sometimes that’s true.
