Most people never give plumbing a thought until something goes wrong. If you have leaks, drips or major failures, you need expert help immediately. At L&L Mechanical we have the friendly, professional specialists you need to handle any type of residential or commercial plumbing maintenance, repair or replacement. 


Here in Minnesota, consistently comfortable indoor heat is crucial during the winter, at home and at work. At L&L Mechanical, we can install a high-quality, high-efficiency furnace and perform clean-and-check service each fall to ensure worry-free heating throughout the winter. And if your furnace needs repair, we can do that, too–promptly.


Hot, muggy Minnesota summers demand air conditioning so you can be comfortable at home or at work. At L&L Mechanical, we can install a high-quality, high-efficiency air conditioner and perform preventive maintenance each spring to give you worry-free cooling all summer long. If your AC ever needs repair, we will be there promptly.

“L&L did all the plumbing on my new house. They have great workers and did a wonderful job. Very reasonable on changes throughout the job. It’s the small things like running 5/8″ to the outside lawn faucets instead of 1/2″ really puts them a step above the competitors. Overall a great company to work with.”
