Claim This BusinessDT Air Conditioning & Heating has called Plano home since 2002, building more than two decades of climate-control expertise across the DFW region. The family-owned contractor holds a 5.0-star average from 366 verified reviews and serves Allen, Frisco, Garland, and surrounding Collin County communities with around-the-clock availability. Every technician on staff is fully licensed and insured, giving homeowners confidence that permits and code compliance are never an afterthought on any installation or replacement project.
What separates this team from neighborhood generalists is their commitment to solving the full spectrum of heating and cooling problems without subcontracting the work. Financing options are built directly into their estimate process, removing a common barrier for homeowners facing unplanned system failures. Combined with free on-site evaluations and transparent pricing that spells out costs before any tools are picked up, the experience is designed to eliminate surprises from first call through final inspection.
Customers across Plano have noticed specific technicians by name. Sergio Perez has relied on Allan for years, citing Allan's straightforward diagnostic assessments and his refusal to oversell repairs. Rita Meyrat received a full-system replacement estimate from Zee, and the installation crew completed the work within the promised window, even working through an attic above 110 degrees. A five-star reviewer from New York noted eight consecutive years of service across multiple rental properties without ever needing to call a competitor. These are the relationships that sustain a two-decade-old business in a competitive market.
Across 366 reviews, technicians receive individual name recognition in over half of all five-star ratings, with Allan, Zee, and Dana cited most frequently for professionalism and diagnostic clarity. Customers consistently describe pricing as fair and transparent, and multiple long-term clients report trusting DT AC across several properties without switching contractors. Emergency availability and same-day response appear across positive reviews without prompting.
