Claim This BusinessAbout D&J Heating & Air LLC
D&J Heating & Air LLC serves residential clients throughout Greenville, South Carolina, earning a flawless 5.0-star rating across 67 client reviews. The company specializes in heating and cooling system repairs, maintenance, and installations for homeowners in the greater Greenville metro area. Technicians at D&J approach each service call with a diagnostic-first methodology, identifying the precise root cause before recommending repairs, a practice multiple reviewers noted prevented unnecessary part replacements and kept final costs reasonable.
What distinguishes D&J Heating & Air from competitors in the region is their transparent pricing structure and refusal to recommend work that homeowners do not need. Several reviewers compared their quotes against competing contractors and found D&J's estimates significantly lower, with one client noting another company attempted to charge $600 for motor housing cleaning that D&J included as part of their standard service. The company also avoids markup on OEM parts when alternatives meet manufacturer specifications, passing those savings directly to clients.
Reviewers consistently highlight two technicians by name: Jimmy and Donovan. Jimmy has responded same-day to heat emergencies, arriving on time and completing repairs during the initial visit. Donovan solved a prolonged mystery for one homeowner, identifying mold growth in ductwork that had contributed to years of unexplained health issues. Another client called D&J after receiving an inflated quote elsewhere, and Donovan provided a fair estimate that saved approximately $1,200 compared to the competitor's proposal.
What Customers Say
All 67 reviews award 5 stars, with Jimmy and Donovan each appearing in multiple positive accounts. Clients frequently mention same-day service availability, transparent quotes, and repairs completed on the first visit without follow-up appointments.
