Claim This BusinessAbout DG Service Company
DG Service Company operates as a heating contractor headquartered in Mattapoisett, Massachusetts, delivering HVAC and refrigeration solutions to both residential and commercial clients across southeastern Massachusetts. The company maintains an exceptional 4.8-star rating drawn from 252 customer reviews, reflecting consistent service quality in a region where temperature extremes demand reliable heating and cooling systems year-round. Their service model encompasses the complete project lifecycle, from system design and new installations to ongoing maintenance and emergency repairs, allowing clients to engage a single vendor for all phases rather than coordinating multiple subcontractors.
What distinguishes DG Service Company from regional competitors is their integrated approach combining design, installation, maintenance, and repair under one operational umbrella, supported by in-house technicians who handle every phase of a project. The company holds Better Business Bureau accreditation, indicating verified commitment to consumer dispute resolution. Their indoor air quality division addresses pathogen control through product installations targeting viruses, bacteria, and mold, a capability that gained prominence during increased awareness of airborne transmission risks. Commercial clients benefit from dedicated refrigeration system services, an niche offering many residential-focused contractors in the region do not provide.
Customer testimonials reveal specific service scenarios worth noting. One client with a complex multi-zone mini-split system described DG technicians as the only service provider they trust after experiencing persistent issues with the original installer, praising communication throughout the troubleshooting process. Another review documented a water damage incident stemming from an improperly cleaned condensate drain line during annual maintenance, resulting in ceiling flooding. The client noted delayed callback responses and disputed billing for emergency remediation of conditions they attributed to incomplete prior service. These accounts illustrate the range of outcomes homeowners may encounter and underscore the importance of verifying scope-of-work completion during service calls.
What Customers Say
Positive reviews consistently highlight technician communication and professionalism, with multiple five-star reviewers praising thorough explanations and respectful on-site conduct. Negative reviews cite billing disputes and response delays rather than outright repair failures, suggesting some clients experienced communication breakdowns rather than technical incompetence.
