Heating & Cooling in New Castle, DE

Expert HVAC Care for Delaware's Historic River City

Who keeps New Castle, Delaware comfortable through every season? Hentkowski Inc. brings Carrier Factory Authorized HVAC expertise to this storied Delaware River community, where colonial-era architecture meets modern comfort expectations. Founded by Dutch settlers in 1651, New Castle's rich heritage is reflected in its beautifully preserved homes and buildings — many of which present unique heating and cooling challenges that require experienced, knowledgeable technicians.


With approximately 5,800 residents and a median home construction year of 1963, New Castle's housing stock spans centuries of building styles and methods. The city's renowned Historic District contains some of the highest concentrations of well-preserved colonial and Federal-period buildings in America, alongside mid-century and modern homes in surrounding neighborhoods near Route 9 and the Delaware Memorial Bridge approaches. Each era of construction demands a different HVAC approach, and our team has the versatility to serve them all with equal skill.
