Claim This BusinessLee Mechanical Inc. operates as a comprehensive MEPF contractor based in Franklin, Wisconsin, serving southeastern Wisconsin and nearby communities with a full spectrum of mechanical, electrical, plumbing, fire protection, refrigeration, and prefabrication services. With a rating of 4.3 stars across 189 verified reviews, the company has built a strong reputation in the region since opening its doors. The company maintains a Caledonia Fabrication and Logistics Facility at 4321 Carol Rd, reflecting significant investment in in-house manufacturing capabilities.
What distinguishes Lee Mechanical from typical HVAC contractors is their vertically integrated service model and specialized commercial refrigeration expertise. As a Lennox dealer, the company handles everything from residential furnace and AC replacements to mission-critical systems for data centers, healthcare facilities, and industrial complexes. Their prefab shop allows same-day fabrication for custom sheet metal and pipe systems, dramatically reducing project timelines. The company operates a 24/7 emergency line for urgent service calls, and their fire protection division maintains the rigorous standards required for systems upon which lives depend.
Customer reviews highlight specific technicians who delivered exceptional service when it mattered most. Dave B. arrived at a homeowner's residence on the same day their 24-year-old furnace failed during winter, providing a quote with installation completed the following morning. Plumber Todd was praised for explaining costs upfront, addressing water hammer with modern devices, and thoroughly cleaning up after a laundry room faucet replacement. For commercial clients, the refrigeration team services supermarket equipment and commercial kitchen systems, handling jobs that require specialized technical knowledge and rapid response.
Of 189 reviews, five-star ratings consistently mention specific technicians by name and praise same-day response times, while lower-rated reviews cite business model changes that affected residential service availability.
