About Greg Key Services
Greg Key Services operates as a family-run air conditioning contractor in Norcross, Georgia, delivering residential cooling solutions to the Atlanta metro area. Owner Greg Key works alongside his son, forming a father-son team that has served customers for more than two decades. The company maintains 24/7 availability Monday through Saturday, providing emergency response for heat-related breakdowns. With 11 verified customer reviews generating a 3.9-star average rating, the business has built a local reputation among homeowners in Norcross and surrounding Gwinnett County communities.
What distinguishes Greg Key Services is the direct hands-on involvement of the owner in every job. Unlike larger operations where homeowners interact only with dispatchers, customers work directly with Greg himself from diagnosis through final installation. The company offers same-day installation for urgent replacements, completing projects within 24 hours of customer contact. Recent installations include Goodman HVAC systems, which the team prices competitively while standing behind their workmanship. This owner-operated model allows for personalized service adapted to each property's specific cooling requirements.
Customer reviews reveal specific scenarios the team has handled. For one lake property owner, Greg installed a new cooling system despite being out of town, taking the initial call and providing remote troubleshooting guidance. Another customer received a same-day Goodman system installation with just one day's notice when their existing unit failed during a heat wave. Long-term customers like Kenneth Picken, who has known Greg for 30 years, describe Greg as someone who supports employees and performs free work for those in need, reflecting a character-driven approach to small business service.
