We believe that air duct cleaning is about technology and service. Therefore, we developed the exclusive INGRA Vacuum Technology® and the 5-Step Ironclad Commitment®.
Our only focus is to improve the quality of the air you breath at a price that all homeowners can afford.

We took a commercial vacuum system and strengthened it to an industrial grade (IN-GRA). We utilize this proprietary technology for all our residential, commercial, and industrial customers in sectors such as food processing, senior housing, and automotive manufacturing. On average, our INGRA® vacuum suction power is 50 to 150% stronger than that of a similar truck-mounted duct cleaning system.

Though we began our cleaning journey 57 years ago, air duct cleaning remains a relatively new concept for many homeowners, with some trying it for the first time. Unscrupulous contractors capitalize on this by intentionally keeping information vague, leading to overcharging and under-service. We pioneered the 5-step Ironclad Commitment® based on customer feedback and inspired by best practices from other service industries, aiming to eliminate uncertainty when selecting the right cleaning company. Our business model focuses on generating ongoing volume through repeat business and referrals, rather than seeking excessive profits from a single service call. Indeed, repeat business and referrals form the bedrock of our company.
