The company holds Minnesota Master Plumber license PM061218, Plumbing Contractor license PC653521, and Mechanical Contractor license MB657602, ensuring every job meets state code requirements.

What distinguishes L&S from competitors is their commitment to transparent, no-pressure service. Technician Joe once spent over twenty minutes on the phone guiding a customer through troubleshooting a furnace he installed nearly a decade earlier, saving the homeowner an unnecessary service call. Several reviewers specifically mention technicians Mac and Joe arriving promptly, offering fair pricing without upselling, and completing work correctly on the first visit. The team handles water heater replacements, boiler maintenance, furnace repairs, leaking pipes, sump pumps, and full re-pipes for remodels and new construction projects.

Customers consistently mention specific technicians who went above and beyond. When Teresa's AC failed during a warm stretch, Mac had her system running again within minutes. Alexander's furnace stopped working, and Joe walked him through diagnostic steps over the phone for more than twenty minutes, successfully getting the unit running within an hour. Jim noted Mac was knowledgeable and never attempted to upsell him, while also offering a cash discount. Multiple reviewers describe the team as professional, timely, and reasonably priced.
