Special Projects

The vast majority of our corporate focus is aligned with providing HVAC-R services to commercial and industrial clients. We offer a number of preventative maintenance programs in an effort to extend the life of equipment and when repairs aren’t going to provide optimal performance, we put together retrofit plans that will prevent downtime and business interruption.

Since 1997 Lor-Mar has been a one-stop source for HVAC repairs, retrofits as well as plumbing installation/repair for your mechanical systems. In addition, we offer sheet metal design, fabrication and installation. Planning and meeting retrofit deadlines is critical to most businesses and with Lor-Mar you get an experienced team and eliminate the planning and coordination of scheduling multiple suppliers.

Occasionally we are asked to review complicated mechanical system challenges for clients out of our traditional commercial customer base. We refer to these as “Special Projects”. We approach every job with the goal of providing long term solutions and client satisfaction and look forward to meeting all of our client needs.
