DND Heating & Air Conditioning LLC

DND Heating & Air Conditioning LLC has built a solid reputation in Knoxville, Tennessee, earning a 4.8-star rating across 23 verified reviews. The family-owned and operated business specializes in residential heating and cooling systems, serving homeowners throughout the greater Knoxville area and surrounding communities. Their team prioritizes honest diagnostics and transparent service, focusing on solutions that save customers money on utility bills rather than unnecessary replacements. Licensed technicians arrive in marked vehicles, equipped to handle both routine maintenance and unexpected breakdowns with equal care.

What distinguishes DND from competitors is their customer-first approach to service calls. Unlike contractors who nickel-and-dime homeowners for every issue, DND waived diagnostics and labor charges when Dani Palmer's system malfunctioned due to clogged filters, a minor fix that other companies might have inflated. Technicians provide upfront pricing comparisons against nearby competitors, and multiple reviewers specifically mention savings on electric bills after DND properly serviced their AC units. The company responds rapidly, with same-day arrival standard and holiday-weekend availability for emergencies.

Customer stories reveal the hands-on nature of lead technician Daniel (also called Danny). When Soren Alsina's heat failed during a holiday weekend freeze, Daniel arrived within 30 minutes, having his daughter in tow heading to dinner, to restore temporary heating until a new thermostat could be installed. Kaylan Sarge noted Daniel arrived exactly on time, something rare in the service industry. Robert Payne, a customer tired of repeated misdiagnoses from Sears Blue Crew and other companies, called DND the first contractor in over five years to properly service his AC unit, resulting in correct cooling cycles and reduced energy costs.
