Claim This BusinessBerry Good Heating and Air has been a fixture in the Marietta and greater Atlanta area, maintaining a 4.7-star average across 135 reviews. The team holds current certifications and operates around the clock, offering residential AC and furnace repair, new system installation, and preventive maintenance plans. Their service area reaches beyond Marietta into Kennesaw, Smyrna, and the surrounding West Georgia communities, where temperature swings between humid summers and occasional winter freezes keep HVAC systems working hard. A weekday free service call promotion is available for customers scheduling during standard business hours.
One distinction worth noting is their 24/7 emergency availability , when a compressor fails at midnight or a furnace quits on a holiday weekend, the same team handles the dispatch. Financing is handled through Synchrony Financial, giving homeowners a pathway to manage costs over time rather than covering a large repair bill upfront. Customer reviews consistently describe the team as non-pressure and honest, a trait reviewers explicitly credit when recommending repair versus replacement. That combination of round-the-clock access, flexible payment options, and straightforward guidance shapes the company's reputation in a market where trust is earned call by call.
Justin draws repeated praise in reviews for arriving the same day or the next morning, a pattern T P has relied on for 14 consecutive years rather than risk an unfamiliar contractor. A recent reviewer noted Justin diagnosed the issue before arriving on site, a level of preparation that compressed the repair timeline. Quar Brown described technicians Justin and Tai as individuals with experience rather than salespeople, crediting them for staying in contact through the entire process and delivering on stated timelines. That consistent follow-through anchors their word-of-mouth growth in a service category where reliability defines the relationship.
135 reviewers awarded an average of 4.7 stars, with Justin named across nearly every positive account. Same-day arrival and honest diagnosis appear in multiple reviews, while Synchrony financing is mentioned as a practical option rather than a selling point. No negative reviews were present in the dataset.
