The Founders

Absolute Duct and ChimneyAbsolute Duct and Chimney Cleaning was founded in January of 2015 by husband and wife, Joseph & Christina Quero. Together, they started Absolute after many years of mastering the trade of Air Duct Cleaning, Dryer Vent Cleaning, and Chimney Services. Their goal was to help create a brighter future for their children.

Absolute’s roots all began in the Quero’s humble 800 sq ft home in El Cajon, CA. Christy answered phones and dispatched jobs while homeschooling her children. Meanwhile, Joe was the sole technician of the company. It wasn’t an easy journey by far, but God graciously answered their prayers along the way. In the span of 2 years, Absolute moved into it’s very own office space and tripled in team members and fleet. Christy no longer had to dispatch and Joe was able to retire his boots. Together, they worked very hard to build both a solid team and a business that could run efficiently on it’s own.

Recently, the Queros took a leap of faith, and moved to Missouri with their growing family. Joe presently serves as Absolute’s business coach to this day.
