For nearly a century, S.M. Lawrence has focused on getting it right the first time. And while we didn’t invent air conditioning or the light bulb, we have been around nearly as long as they have. 

Since 1917, we have been serving clients large and small with a simple philosophy... take care of the customer and the customer will take care of you. With our rich history in the contracting business and the design-build approach to construction, we have tackled just about every problem you can imagine. 

Today, we have grown into a nationally recognized full service mechanical and electrical contractor serving a majority of the United States. Our goal is to keep your facility running without interruption. 

Whether it is designing HVAC systems, electrical services, plumbing and piping systems, or maintaining your building once it’s complete... our dedicated team won’t stop until you are satisfied. 

As part of Comfort Systems USA with over 40 sister companies, S.M. Lawrence has the capabilities and the resources to be a part of any building project. In addition to an in-house engineering staff, we have electrical, plumbing, process piping, HVAC, and service capabilities to provide a single source for all of your mechanical and electrical needs. 

You can take comfort in our understanding of the ever-changing technologies and our grounded, time tested customer loyalty as we put our team to work on your behalf.
