Bests & Worsts Reviews from Amazon

I am NOT even close to the home improvement type. So if things go south I'm in trouble. I looked over the Honeywell box and Honeywell wisely stated your HVAC wiring to the thermostat MUST have a "C wire" or the new thermostat would not receive power and would not function. So being the cautious person I am I asked three wandering separate Home Depot guys "If there was anyway I could "tell" if I had a C wire. The first guy said, "oh if you have AC you have to have a C wire." I continued reading the box and another walked by and asked if I needed help. I asked him the same question. He said, "If your home is new you definitely have one". I then asked #3 and he said, "you should". And then gave me the "you could always return it". So I took the shot and bought it. I followed the directions carefully. I saw plenty of wires going to the existing thermostat so I assumed I was safe as I saw more than 4. I disconnected the old thermostat and began to affix Honeywell's supplied wire stickers -with a lot of different letters in the alphabet that matched all the letters on the existing and figured I was safe and this would be a simple "swap out". Well guess what? My new, state of the art home had everything but a C wire. Nervousness sets in. I rip through the quick setup guide and read about "alternative wiring options for those without C wires. It was a very nicely done YouTube video that tells me I will have to use the "G" wire in place of the missing "C" wire. And by doing that I would lose the ability to only run the fan manually. No biggie. Then the video sends me down to the furnace to do the same G to C move on the main panel and then jump the "Y" to "C" with an 18 gauge wire. Yeah I have tons of those laying around my house. Now panic begins to set in. Putting the old thermostat back or worse having no heat in Northern Utah over night in end of Winter or worse, having to call an H VAC guy on a Sunday for "after hours" home service that "costs the same" while I listened to a lecture about not being trained to do this and getting a $300.00 bill did not appeal to me. To finish this long story my neighbor is an electrician. He speaks mostly Spanish but after reading the Spanish enclosed instructions and watching the YouTube video like 4 time he got it to work. Otherwise an excellent WiFi thermostat system -which I can do and fully understand. It will help a good deal while I am traveling. I am an empty nester. So word from the now wiser, if you aren't comfortable with this stuff leave it to those that are.
