Engineered Design & Build
If you value time and results, Design/Build delivers on both counts. Different from plan and spec, the Thayer team is involved from the earliest stages of a project, this allows us to ensure that all factors and variables are considered in the design; that the components are of the highest quality’; that the installation is performed correctly and on time; and that your system will perform as promised. Single Sourced Design/Build is the most efficient method of delivering quality and efficiency in a construction project. It is about getting it done right the first time with a solution designed to your specific application

Equipment Maintenance
Unplanned HVAC/R equipment repair or replacement can derail even the most well-planned budget. A comprehensive preventive maintenance program has proven to reduce risk and operating costs by as much as 10-30%. Preventive maintenance is maintenance that is regularly performed on equipment to lessen the likelihood of it failing. Initiating a preventive maintenance program reduces the chances of little mechanical problems becoming big problems. Thayer Corporation recognizes and acknowledges the need for preventive maintenance, and is committed to providing customized maintenance agreements throughout the State of Maine to customers both large and small.

Lighting
Lighting is an often overlooked, underappreciated aspect of business. In reality, the importance of having the right commercial lighting is critical. When considering the choices for lighting a commercial space, it is important to be able to determine which lighting best fits your space or use. Between initial costs, energy expenses, replacement costs, lumen output, and color rendering accuracy, choosing the ideal lighting system can quickly become overwhelming.
Thayer Corporation has devoted team members to offer you energy efficient lighting solutions. Whether your current lighting system needs repair or you want to do a complete lighting redesign, we’re here for you.
