In order to understand air duct or HVAC vent cleaning, it’s important to first understand what HVAC stands for:
Heating
Ventilation
Air Conditioning
HVAC systems are responsible for airflow within a building; they ensure that the air is both safe and at a comfortable temperature. From a central unit, air is distributed throughout a building through a range of air ducts. Because of the way air ducts serve an entire building, if even small amounts of contaminants are present, they can filter into the overall airflow, affecting many people.
