Dual stage heat and AC
Just what I needed to run dual stage heat and dual stage AC. I needed this after updating a unit and the HVAC guy didn’t update the wiring, leaving me with single stage heat. I found that running reverse staging was more efficient too.

Stop Twirling Dog Fence Wire
Instead of wrapping two lengths of dog wire together to negate the transmission, I had the idea of buying something like this and it worked perfectly. Don't waste your time "twirling" lengths of dog fence wire.

Made in USA high quality.
Worked out great. No issues with the wire. I needed to rewire 2 thermostats in my home to upgrade to 5 wire for 2 new HVAC units installed.This wire worked fine, stiff enough to push it through the existing conduit without a problem.
