Hentkowski, Inc.

Hentkowski, Inc. has served Wilmington and the greater Delaware Valley for multiple decades, building a reputation through word-of-mouth recommendations rather than advertising. With 133 customer reviews averaging 4.7 stars, this contractor operates 24 hours a day, seven days a week, providing emergency availability that local homeowners can rely on during extreme weather. The company handles residential heating and cooling systems throughout New Castle County, including Newark, Middletown, and the greater Wilmington metro area.

What distinguishes Hentkowski from larger HVAC companies is their diagnostic integrity and commitment to finding the most cost-effective solution for homeowners. Reviewers repeatedly praise the team for identifying warranty coverage that other contractors missed, potentially saving customers thousands of dollars. The company has built an embedded presence within the local community over years of operation, with a leadership team that reviewers describe as knowledgeable and accessible.

Customer stories from reviews illustrate the company's approach. Diana V. described how Kim used her heat pump's serial number to discover her unit was still under warranty, while John diagnosed the problem as electronic rather than a failed compressor, saving her from a $12,000 repair other companies had quoted. Dr. Abraham Philip noted technician Mr. Salman arrived on time, explained the maintenance process thoroughly, and treated the home with respect. Korinne Ross mentioned her oil-to-gas conversion resulted in the warmest her house had ever been, with the team being "the kindest people to work for us."
