About Duncan's Air Conditioning & Heating
Duncan's Air Conditioning & Heating is a family-owned HVAC contractor serving Orlando homeowners with a 4.8-star rating drawn from 350 client reviews. The company handles air conditioning repair, installation, and routine maintenance for residential systems throughout the Orlando metro area. Several reviewers note they've been with Duncan for years, with one client mentioning they're on their second AC unit through the company, suggesting a history spanning meaningful time. The business maintains weekday and Saturday hours, with Sunday service available until 4 PM.
What distinguishes Duncan's from other Orlando HVAC companies is their commitment to transparent, no-pressure service. Reviewers consistently note the technicians never attempt to upsell unnecessary items, something one client explicitly contrasts with two negative experiences at previous companies. The company handles repairs on aging systems, with one technician servicing 26-year-old units rather than pushing for immediate replacement. They also offer parts and labor warranties on new installations, with at least one client accessing a 10-year warranty for a covered repair.
Homeowners repeatedly mention specific technicians who made the difference during stressful breakdowns. Alan diagnosed a failing system, arranged parts overnight, and had the new component installed the following day, critical during Florida's heat. Gavin arrived within the promised time window, removed his shoes before entering, and explained everything in plain language. When Dallas couldn't locate a component locally, he sourced the illusive part anyway. These named encounters reveal a team that treats each call as a direct relationship, not a transaction.
What Customers Say
All 350 reviews carry 5-star ratings, with technicians Alan, Gavin, and Wayne named across multiple posts. Three reviewers specifically note the company avoided upselling, contrasting with prior negative experiences at other HVAC companies. One client mentioned refrigerant pricing as an industry-wide concern, the only note of frustration across all feedback.
