Poor indoor air quality (IAQ) is a growing national problem caused primarily by negative pressure leaks and tight building envelopes. Without proper ventilation, a variety of harmful pollutants accumulate inside the ductwork attached to your HVAC equipment. If not adequately addressed, these contaminants continually recirculate through the system and can aggravate respiratory conditions such as asthma, allergies and COPD.
Our Air Duct Cleaning Services
A professional duct cleaning service will eliminate the dirt, dust, grime, pollen and mold that build up on the interior surface of your duct network over time. The duct cleaning process also removes contaminants from critical internal equipment components including:
- The plenum
- Heat exchanger
- Condensate drain lines and pan
- The interior of the air handler
- Supply and return registers
- Blower, housings and motors
- The evaporator coil
- VAV boxes
For every air duct cleaning remediation project, we send trained technicians equipped with cameras and mirrors to accurately assess the condition of your ductwork and HVAC equipment. If the system requires cleaning, the registers are sealed with a pressure sensitive tape, and access holes are cut into the supply and return duct lines.
When the ductwork is prepped, a powerful vacuum that meets NADCA standards is attached to the installed collar. Flexible forced air whips and mechanical brushes are used to agitate and dislodge any material that is stuck to the duct wall. The system is turned on, and the ductwork is placed into a substantial negative pressure. Dander, hair, debris and other impurities are pulled out of the ductwork and deposited into a sealed container.
The Benefits of Clean Ductwork
Periodic duct cleaning provides an excellent return on investment. Some of the more important benefits include:
- Improved indoor air quality
- Lower HVAC maintenance costs
- reduced utility bills
- Fewer furnace and AC repairs
- Extended equipment life
