About Gregory & Martin Inc
Gregory & Martin Inc operates as a heating contractor serving Derry, Pennsylvania, and surrounding communities. The business holds a 4.5-star rating drawn from 18 customer reviews, indicating consistent service quality that residents recognize and recommend. Customers interact with team members including Bev who handles initial contacts, and technicians like Justin who tackle complex heating system repairs. The company maintains standard weekday hours Monday through Friday from 8 AM to 4 PM, with Saturday and Sunday reserved for emergency callback service. This scheduling structure reflects a focus on predictable service windows while retaining flexibility for urgent situations that customers cannot predict.
The contractor distinguishes itself through responsive same-day service capabilities and transparency throughout service calls. Reviewers consistently note that technicians explain what they are doing rather than performing work without homeowner awareness. One review describes a scenario where the team overcame difficulty locating parts for a heating system repair, demonstrating persistence rather than suggesting the job was impossible. This approach aligns with what multiple reviewers describe as fair pricing and willingness to see repairs through to completion.
Customer stories from reviews highlight specific technicians and the scenarios they handled. Justin earned recognition for repairing a heating system when parts proved difficult to source, keeping the homeowner informed throughout the process. Greg addressed an AC unit that was not working properly, arriving promptly and maintaining professional conduct. Reviewers also mention Michael and Bill handling a furnace replacement under warranty, describing the service as fast and professional. These named scenarios demonstrate that the contractor sends identifiable team members who follow through on problems rather than offering temporary fixes.
What Customers Say
Seven of eight reviewers award 5 stars, with same-day service and explanatory communication appearing as consistent praise. Negative feedback centers on callback responsiveness rather than diagnostic skill or pricing.
