How We Work
Every building automation project has its own set of requirements. Here is how we typically move from initial contact to a finished installation.
We start by reviewing your building layout, existing mechanical systems, and what the BAS or HVAC control system needs to accomplish. This shapes the scope before any work begins.
Once we understand the project, we map out the control wiring runs, panel requirements, and any low-voltage pathways. Clear planning prevents problems during installation.
Our electricians pull the necessary wiring, install control panels and enclosures, terminate sensors and actuators, and connect everything to your BAS or HVAC control equipment.
Before we wrap up, we verify that all wiring is correct and that the control signals are reading properly. We walk you through what was installed and how it connects to your system.
Frequently asked
Common questions get answered quickly so the page feels more trustworthy before someone reaches out.
Q1
A building automation system connects and manages mechanical systems like HVAC, lighting, and ventilation from a central point. Klein Electric 207 handles the electrical and controls wiring that makes those connections possible.
Q2
Yes. We work on commercial buildings of various sizes as well as residential properties that use zoned or automated HVAC controls. The scope changes depending on the system, but the electrical work follows the same standards.
Q3
Retrofit projects are common. We assess the existing mechanical and electrical infrastructure, then wire in the new control components. Many older buildings in Maine can be upgraded without a full electrical overhaul.
Q4
We serve clients throughout Maine, including Oakland, Augusta, Waterville, Bangor, Winthrop, Belfast, Rangeley, and Freeport. For larger commercial projects, we travel statewide from Kittery to Presque Isle.
Q5
Yes. On most BAS projects, we coordinate with the HVAC contractor and the controls vendor or integrator. Our role is the electrical and controls wiring. We are comfortable working as part of a larger project team.
Q6
We wire temperature sensors, humidity sensors, occupancy sensors, actuators, variable frequency drives, thermostats, and zone controllers. If it connects to a BAS or HVAC control panel, we can handle the wiring.
Q7
Most BAS and HVAC control wiring is low-voltage, but some components connect back to line-voltage power sources and panels. We handle both sides so the full controls circuit is covered under one electrician.
Q8
Call us at (207)250-4403 or send an email to office@kleinelectric207.com. Describe the building, the system you are working with, and where you are located in Maine. We will take it from there.
