No more than idling a car in your basement.

It’s nothing like that.

Calgary should be fine, a rotting furnace is much less likely here. Its places like Victoria/Vancouver where you have salty acidic moist air that might find its way into your furnace - where you might want to replace things based on recommendations.

High eff are doubly finiky in Calgary because of our high altitude (low oxygen density). Literally getting a double capacity blower to keep the flames a nice blue might be a good idea.

Branden at Xtreme Furnace has been incredibly helpful to me dealing with all the issues on my high efficiency furnace. Recommended to me by another beyonder and he's been awesome.

So turns out I do have a low voltage system and can install an Ecobee.. however I don't have a C-wire running to the Thermostat, so I need to buy a Fast Stat Common Maker.. I can't seem to find it anywhere though.. anyone knows where I can buy a Fast Stat Common Maker?

you probably just need a transformer, i had to install one for my ecobee as well, i dont remember the details exactly but i am sure i found it via google, i think i bought the transformer from BE electric in town.

Option 2, transformer, I installed mine right on the furnace kill switch box and tapped in to the wires in the box. then i used my existing thermostat wires to pull a new run with 6 wires in it. i think it only needed 3-4 but its all i could find at home depot.

oh also, related to this thread DO NOT GET A CARRIER FURNACE, my inlaws got one in their house, brandnew house 10 years ago, they've already had several repairs at $1000+ each time... proprietary parts with huge markup... latest one is an inducer motor, cant buy just the motor which would be maybe $100, nope, you can only buy the whole assembly for $1150, that's just the part, install is extra.

I had to use one at my old house and I just ordered it on amazon. If you order today it will be here Thursday or Friday.

Do you only have two wires going up from furnace to thermostat or do you have a bundle with some spare unused wires? if you have a bundle with unused you won't need the Common Maker. The common maker is really only needed if you only have two wires and don't want to fish/pull a new bigger bundle up. At my new place i ended up hiring an electrician to pull some new 18/7 wire up. 7 wires is overkill for just heat control but doesn't hurt to have the extras in case you want to wire in your humidifier or add an A/C down the road.

Also do you have a C terminal on the furnace side? If your system is low voltage (24V) and not millivolt then you would already have a transformer and can just simply tap into that if your furnace doesn't have a control/motherboard with a labeled C terminal.

I only have 2 wires going up to the Therostat, but I do have a C-terminal on the furnace side. The Fast Stat would be the easier DIY way for me, although I can't find it anywhere. The Common Maker model is not on Amazon at all for some reason; just the 3000-5000 models. Not sure why it's so hard to find and they don't sell at Lowes/HomeDepot/Rona. Unless I can also use the 3000 models to add the Common...

We *might* install an AC this summer (pending if we can justify the cost)... maybe worst case I can wait until then as it sounds like they will need to pull more wires up anyway if we do get an AC..

interesting... i ordered mine from amazon a couple years ago but just checked and looks like it's not on there any more. I even went to my past order to get the link but now it says 'page not found'.

if you can't find one from somewhere else it's worth looking into hiring an electrician to fish some wire for you. I found a guy on kijij and he did it for me for $80 cash but i had to provide the wire. This is the one i ordered: https://www.amazon.ca/dp/B0069F4HEU/..._wE0rCbE4N6HBK

i went this way because i wanted my humidifer wired in and needed the two extra wires.

Lowes sells a transformer if you want to add a smart thermostat to your old furnace
