McDonough HVAC Company's Patent-Pending Diagnostic System Cuts Callbacks 90% and Delivers a 99% First-Time Fix Rate

Absolute Best Air owner, a third-generation HVAC contractor and former firefighter-paramedic, built the software in-house

MCDONOUGH, Ga., Oct. 22, 2026 /PRNewswire/ -- Absolute Best Air, Inc., a residential HVAC company serving Henry County and South Metro Atlanta, today highlighted results from AI IAQ, a proprietary diagnostic system the company developed in-house. A patent application for AI IAQ is pending with the U.S. Patent and Trademark Office.

AI IAQ helps Absolute Best Air technicians diagnose repairs on both heating and cooling systems, and lets them complete the company's 151-point inspection in about 30 minutes, down from roughly three hours. Since deploying the system in March 2026, Absolute Best Air has reduced callbacks and return trips by 90% and achieved a 99% first-time fix rate.

Over the past year, Absolute Best Air has also grown from 123 to 715 Google reviews while maintaining a 4.9-star rating.

AI IAQ was built by company owner David Longino, a third-generation HVAC contractor who learned the trade from his father, who learned it from his grandfather. Before leading Absolute Best Air, Longino served as a firefighter and paramedic and ran air conditioning calls between 24-hour station shifts.

"Homeowners deserve to know exactly what's wrong with their system and why, not a guess," said Longino. "We built AI IAQ so every recommendation our technicians make is backed by real measurements, and so we fix it right the first time. If a repair will do the job, we'll tell you. If replacement makes more sense, we'll show you the numbers."

Absolute Best Air is a BBB Accredited Business with an A+ rating. It is an authorized dealer for Daikin, Goodman, Trane, and Mitsubishi Electric and is a Honeywell Pro. The company offers 24/7 emergency service dispatch.
