At Future Supply, we work only with wholesale HVAC partners — including contractors, distributors, and supply houses. Our extensive inventory features CSA-approved 600V TC-ER wire, thermostat cables (18-2 to 18-10), adjustable aluminum heat pump stands, and professional-grade silicone sealants. Every product is sourced for quality, priced for wholesale advantage, and backed by fast, reliable shipping. We don’t sell to the general public — we exist to help HVAC trade professionals complete jobs faster, increase margins, and keep their customers satisfied.
