Claim This BusinessDale Sims Heating & Air Conditioning has served Chamblee and the broader Metro Atlanta region since 1982, making it one of the more established commercial HVAC contractors in DeKalb County. The company holds Georgia license CN210230 and maintains a 4.3-star rating gathered across six customer reviews, a respectable track record for a business operating in a demanding technical field. All service technicians at Dale Sims complete five years of training at the Mechanical Trades Institute, and the team brings an average of 30 years hands-on experience in their respective specializations. This depth of institutional knowledge positions the contractor to handle complex retrofits and specialty systems that newer competitors often lack the expertise to approach.
Dale Sims sets itself apart through specialized credentials in building automation and energy management. The company employs three Niagara AXCertified Technicians and operates as a KMC service provider, offering open-systems architecture with industry-standard protocols like BACnet and Niagara. Their VRF and ductless split system capabilities include factory training and certification for brands spanning LG, Sanyo, Daikin, and Mitsubishi. The contractor also offers free energy audits for commercial facilities and provides 2-hour emergency response for data center operations, a critical differentiator for businesses where cooling downtime translates directly to revenue loss.
Customer reviews highlight Logan as a technician who goes beyond the initial complaint to diagnose root causes. In one review, Logan resolved a system-freezing issue and traced a separate humming noise during heat call to a buildup of dog hair in the ductwork, addressing both problems in a single visit. This methodical approach, identifying the underlying cause rather than treating symptoms, echoes the company's stated philosophy of training technicians to get the job done right the first time.
Two published reviews, both 5-star, praise specific technicians (Logan) and detail problem-solving that went beyond the original complaint, with one customer noting thoroughness resolving both a freezing system and an unrelated noise caused by duct debris.
