Thermostat Wire
When installing or upgrading your thermostat, running a new cable from your furnace to the thermostat is crucial for ensuring proper function. Typically, the C-Wire (common wire) is responsible for delivering constant power to your thermostat, enabling it to operate efficiently and set heating and cooling schedules. At Jackson Systems & Supply, we offer a wide variety of thermostat wire options to meet your specific needs. Whether you’re a contractor or a DIY enthusiast, we provide multiple wire weights, lengths, and custom wire length options tailored to your project.
