Straight from the Hart — Case studies and success stories from contractors using Positive Air Duct Cleaning® and the RamAir system.
From struggling with traditional methods to 2 homes per day with one technician
Bob Jordan of PuroClean was using conventional negative air equipment on residential jobs. The process was slow, physically demanding, required multiple technicians, and often damaged modern flex ducting. Margins were thin and jobs took too long.
After adopting the RamAir Positive Air system, Bob transformed his operation. One technician now routinely completes two full residential jobs per day. The non-invasive method protects flex duct, eliminates the need for large external machines, and delivers visible results customers can see in real time.
A large casino with 60,000 CFM rooftop units was quoted 3 months and a very high price using traditional methods. David Hart’s team completed the full remediation in just 10 days using Positive Air — at roughly half the quoted cost.
Multiple homeowners reported dramatic improvements after Positive Air cleaning. One mother shared that her son’s asthma symptoms were “all but gone.” Others noted significantly less daily dusting and better breathing within days.
