American Air Plus

American Air Plus has earned a flawless 5.0-star rating from three client reviews, operating as a licensed HVAC contractor in Los Angeles under the direct leadership of owner and chief technician Greg McCullough. The firm has cultivated lasting relationships with homeowners across multiple cities, including dedicated service relationships in El Cajon, where the team installed a complete zoned system for an out-of-area client. This long-tenured contractor specializes in supporting aging systems for clients who prefer to extend existing equipment before committing to full replacements, offering both repair expertise and new installation services for residential properties throughout Southern California.

The company's owner-operated structure means Greg McCullough handles every project personally, from initial consultation through final installation. Client reviews confirm that American Air Plus provides fixed pricing upfront, eliminating the uncertainty of time-and-materials billing. The firm stands behind completed work unconditionally, with Greg returning to address any issue at no charge, whether it falls strictly within HVAC scope or not. This accountability model, combined with transparent quotations, distinguishes the company from contractors who subcontract installations or rely on hourly billing structures.

Reviewers specifically named two technicians who delivered exceptional outcomes under difficult circumstances. When a 100-year-old Spanish historical property required central air in Los Angeles, 'Cowboy' navigated coved ceilings and a narrow driveway that required crane equipment, calculating proper unit sizing and completing an installation that cools the entire home in minutes. Greg McCullough similarly earned high praise for nursing a temperamental older system through years of repairs before guiding the client smoothly into a new replacement, then appearing at no charge months later to fix an unrelated dryer knob. Both technicians demonstrate the willingness to go beyond standard HVAC scope when clients need assistance.
