Claim This BusinessRalph G Degli Obizzi & Sons has served the Wilmington heating and mechanical contracting industry for multiple decades as a family-operated business. The company holds appropriate state licensing for heating system installation and repair work, with 12 verified customer reviews generating a 4.3-star average rating. Based in New Castle County, the contractor serves residential homeowners and commercial property managers throughout Wilmington and surrounding Delaware communities including Newark, Bear, and the greater Christiana corridor.
With limited publicly available information about specific brand partnerships or advanced certifications, the contractor operates as a traditional heating and mechanical services provider without prominently advertised specialized equipment offerings. The family business model suggests personalized service attention, though prospective customers should verify specific capabilities and warranty terms during initial consultation. Given the absence of detailed website documentation, homeowners are encouraged to request comprehensive proposals outlining proposed equipment specifications, labor guarantees, and anticipated project timelines before committing to service agreements.
Customer feedback reveals mixed experiences. One reviewer recounts a long-standing personal connection with Dan Degli Obizzi, describing the team as approachable and down-to-earth. Another reviewer specifically identifies the company among the best mechanical contractors operating across the tri-state Delaware region. However, a serious safety-related complaint describes reckless driving behavior involving a company vehicle, which prospective clients may wish to discuss directly with management.
4 customer reviews demonstrate strong satisfaction, with three reviewers awarding 4-5 stars and specifically praising the team's family-oriented approach and mechanical contractor expertise. 1 review filed a 1-star complaint regarding driver conduct, representing the sole critical perspective across this sample set.
