Nick's Dun-Rite Air Services LLC

Nick's Dun-Rite Heat & AC Services has kept North Texas homeowners comfortable since 1990, building more than three decades of local expertise in Collin and Dallas Counties. The company holds proper licensing for air conditioning and heating work, and their technicians are EPA-certified to handle refrigerants safely. With 281 customer reviews generating a 4.8-star average rating, the contractor has earned consistent trust across the Plano, Allen, and Frisco communities. Their around-the-clock availability means help arrives whenever a system fails, whether during a sweltering July afternoon or an unexpected holiday evening.

What distinguishes Nick's Dun-Rite from neighboring contractors is their manufacturer breadth and specialized insulation division. They service every major residential brand including American Standard, Bryant, Carrier, Goodman, Lennox, Rheem, Trane, and York, meaning your warranty stays intact regardless of equipment age. Their spray-in radiant barrier installations reflect up to 80% of radiant attic heat while cutting attic temperatures 20-24 degrees, a meaningful advantage in Texas summers. The company also handles in-house air duct fabrication, addressing a common source of energy waste that can inflate utility bills by up to 30% when ducts are poorly designed or leaky.

Customer experiences reveal the human side of this operation. When Rebecca Friedman faced an unexpected HVAC breakdown, technician Robert went above and beyond to restore her system, earning a five-star endorsement. Kristen Smith found same-day relief when Nick personally diagnosed her AC issue, explained the problem clearly, and even provided future replacement quotes while on-site. However, one review from early 2026 describes a $3,000 pipe replacement that was never completed after technicians claimed her roof was too steep, with the customer reporting repeated missed callbacks. This single negative experience stands against largely positive feedback praising responsive emergency service and knowledgeable technicians.
