Naughton Mechanical

Naughton Mechanical LLC delivers heating and cooling services across Northwest Indiana and the greater Chicagoland region from its base in St. John. The family-owned company has operated for over two decades under owner Mike Naughton, whose three decades in the trade exceed the business tenure itself, providing customers with deep expertise uncommon among regional contractors. Five verified five-star reviews anchor the company's reputation in Lake County, where they install systems ranging from modest residential units to twenty-ton commercial rooftop equipment serving restaurants and hotels.

The company holds exclusive product partnerships that shape equipment recommendations, including designation as a Trane Comfort Specialist offering Trane furnaces and air conditioners alongside Rheem water heaters, Aprilaire humidifiers, and Spaceguard filtration. This distributor-level access means technicians install brand-name components rather than second-tier alternatives. Generator services, indoor air quality assessments, water quality treatment, and custom ductwork represent specialized capabilities many Lake County competitors cannot match. A satisfaction guarantee backs every project, reinforcing their claim of doing work correctly on the first attempt.

Customer scenarios reveal technician specificity: Elissa Smith described a same-day furnace part replacement during a heating failure, while Mark Bertrand detailed a full furnace and condenser installation led by technician Jeff, praising the crew's precision with every component from glued pipes to threaded fasteners. Their emergency service operates around the clock, a critical resource when Lake County winters push heating systems to failure.
