John Air Duct Cleaning & HVAC

John Air Duct Cleaning & HVAC operates from Encinitas, California, delivering specialized air duct sanitation services to coastal San Diego County residents. Though the company does not list a founding year or contractor license number in public records, their Google profile reflects 20 client reviews all awarding a perfect 5-star rating, a consistency rare in the trades. The crew maintains standard operating hours from 6 AM to 10 PM daily, providing weekend availability uncommon among regional HVAC specialists. Their service radius encompasses Encinitas, Cardiff-by-the-Sea, Leucadia, and neighboring Carlsbad neighborhoods, reaching homeowners within approximately 15 miles of their base.

Unlike broader HVAC companies offering repairs, installations, and maintenance under one roof, John Air Duct Cleaning & HVAC concentrates exclusively on duct sanitation and dryer vent clearing, a narrow specialization that rewards customers with focused expertise rather than divided attention. Reviewers consistently reference the technician's use of negative air machines capable of reaching deep into trunk lines and branch ductwork, a professional-grade approach distinguishing their process from superficial vent covers tidying. The company does not market manufacturer partnerships, rebate programs, or workmanship guarantees on record, nor does a public website exist detailing equipment brands or service certifications.

Several reviewers describe specific scenarios demonstrating the team's responsiveness. One customer credits technician Tom with professionally explaining how clogged ductwork strains HVAC systems and subsequently cleaning every return and supply vent using heavy negative pressure equipment. Multiple reviewers report noticeable reductions in utility expenses following service, with one customer noting immediate improvements on the first post-service billing cycle. The company completed work for families experiencing allergy flare-ups caused by accumulated dust and debris, delivering what one reviewer described as a seemingly brand-new HVAC system without requiring component replacement.
