Dickerson Heating & Air

Dickerson Heating & Air serves Kennesaw, Marietta, and surrounding Georgia communities as a full-spectrum HVAC and plumbing contractor. With 545 verified reviews yielding a 4.9-star rating, the company has earned a reputation for technical precision and responsive service across residential and light commercial projects. Their service menu spans air conditioning, heating, heat pump systems, indoor air quality solutions, and an array of plumbing services including water heater installation, leak detection, and whole-home water treatment. The company operates Monday through Friday from 8 AM to 5 PM and maintains a financing program alongside a protection plan for ongoing system care.

What distinguishes Dickerson Heating & Air is their multi-trade capability. Rather than limiting service to heating and cooling alone, they handle plumbing needs that many HVAC contractors subcontract out, including bathroom remodeling, repiping, backflow testing, and water quality systems. Their indoor air quality offerings extend beyond standard filters to electronic filtration and UV light systems. The company also provides ductless mini-split installations for homes without traditional ductwork, a growing niche in the Atlanta metro area. Customers mention same-day response for urgent issues and a determination to see problems through, even when repairs require multiple visits.

Reviewers consistently name specific technicians who handled their situations. Jacob appears across multiple reviews for diagnostic clarity and system restoration. For one homeowner, a heat pump installation involved Jacob explaining options upfront, followed by Sam and another technician completing the install, with Devon arriving same-day when a thermostat issue surfaced days later. Another reviewer describes Devon and Alex tackling a particularly stubborn wiring challenge that required three separate visits running wire from the attic through walls to the thermostat. A third customer credits Jason and Chris with a decade of maintenance care, noting they treated her home as if it were their own. These named accounts reflect the hands-on, problem-solve ethos pervading the reviews.
