Claim This BusinessAbout V.M. O'Leary Sheet Metal & Heating
Since 1946, V.M. O'Leary Sheet Metal & Heating has operated as a family-owned enterprise serving Cary, Crystal Lake, Algonquin, and surrounding McHenry and Lake County communities. The company holds a 5.0-star rating across 47 verified client reviews, reflecting a commitment to technical precision that spans three generations of the O'Leary family. Owner Vince O'Leary, a former union sheet metal craftsman, leads a team that handles both residential furnace repairs and commercial HVAC installations across Chicago's northwest suburbs.
What distinguishes V.M. O'Leary from typical HVAC contractors is their in-house custom sheet metal fabrication capability, a specialty that allows precise ductwork modifications and bespoke ventilation solutions unavailable through volume-driven competitors. The company offers Aeroseal duct sealing technology to address air loss in aging systems, alongside boiler, radiant heat, and snow melt installations that serve clients throughout northern Illinois winters. Their maintenance plans provide year-round system monitoring, while financing options make new equipment purchases accessible for homeowners facing unexpected furnace failures.
Customer reviews consistently highlight same-day response times and the owner's hands-on involvement. Jonathan Wuerger, a commercial project manager, described receiving furnace installation within 48 hours of his initial call, praising the craft quality and transparent pricing. Multiple reviewers cited Vince's direct involvement and his team's punctuality, with several noting the company resolved issues that previous contractors failed to diagnose correctly.
What Customers Say
Forty-seven reviewers award a perfect 5.0 average rating, with customers repeatedly citing Vince's same-day arrival during emergencies and fair, itemized pricing. Three recent reviews specifically mention furnace replacements completed within two days of the initial service request.
