Fast shipping!
I first ordered a part for my air conditioner via Amazon and it said it would take 5 days for delivery. Five days in the middle of summer in Florida would not cut it!! I ordered the part from the Supply House because of a video I saw in YouTube and received it less than 2 days!

Fantastic product!
This was installed for me by a SCE contractor. I had an old (ancient) thermostat, old house, and no common wire. This product is ingenious! Now I have a smart thermostat that I can operate from anywhere. Very happy.

Great buy and price
I bought this product to gain a "C" wire for my HVAC. Easy to install and does exactly what it was designed to do. I would recommend.

It helped me with a set of wires with a bad lead in the set.
It worked as expected, it went in pretty easily and saved me a visit from an HVAC tech.

Great product, great support!
This device allowed me to purchase and use an updated network thermostat and forget about batteries. A nice, practical product with great support. It's pretty straight forward to install...I did have a small problem but I called did a live chat session, sent a couple pictures and they discovered a wiring error on my part. Made the correction and everything is working perfectly. Well worth the cost.
