Claim This BusinessDean Plumbing Heating & Cooling, now operating as part of All-Star Heating & Air Conditioning after a 2024 merger, serves Knoxville homeowners from its Neal Drive location with full licensure (TN 76977, TN 4951) and a 4.5-star average across 280 reviews. The contractor's service footprint extends across neighborhoods including Farragut, Powell, Karns, and hard-to-reach areas like Tellico Village and Whispering Hills, offering both HVAC and plumbing under one roof. Weekend and holiday response is standard, not exception, for this locally-rooted operation.
What distinguishes Dean / All-Star is their commitment to rapid turnaround and equipment breadth. They handle ductless mini-split systems alongside traditional heat pumps and furnaces, while the indoor air quality lineup includes UV lights, air scrubbers, and whole-home dehumidifiers, addressing Tennessee's humid summers and transitional seasons unlike standard filter-change-only contractors. Their membership program provides scheduled maintenance with priority scheduling, and the merger expanded their plumbing capabilities for one-company resolution of mixed HVAC and pipe issues.
Reviewers specifically named technicians who arrived when other companies couldn't. Bryan diagnosed and repaired a radiant-floor boiler in a 79-year-old home in 2019, while Nathan reached a homeowner within one hour of calling in 2021. During a July heat wave, Megan Doran's AC was diagnosed same-day when competitors quoted three-week delays, saving her Fourth of July weekend gathering. Owner Moody is noted as personally available by phone for ongoing clients.
Positive reviewers cite fast same-day response and named technicians Bryan, Nathan, and Moody. Negative feedback centers on pricing transparency and diagnostic disagreements. Five-star reviews mention heat wave emergencies and radiant heating expertise; the single 1-star review involves a billing dispute over coil diagnosis.
