1. Arrival, Customer Briefing and Setup

We arrive at your home with our POWERFUL VACUUM TRUCK. This is the most efficient way of removing large debris     from your duct system. We will need setup space in your driveway.

Technicians will perform a walk through with you to address any questions or concerns. After that is complete they will  protect your floors with drop cloths and continue the setup.

The vacuum hoses will stretch from our truck into your home to where your furnace is located.All dirt and debris taken from your duct system will be whisked outside to our truck where it is stored and taken with us.



2. Removal of  Vent Covers

5. Air Conditioning Coils


Cleaning of the air conditioning coils may help lower your energy costs as a dirty coil can restrict your airflow and make your system work harder.

The coils and coil drain pan are an ideal breeding place for mold and bacteria,  having this area cleaned is an important step in having the ENTIRE SYSTEM cleaned.

Many indoor air quality problems start with dirty coils and humidifiers. Learn more: The NADCA Energy Research Project
