Are you sure that an ordinary thermostat "turns your heater on" right away? I know that my furnace, regardless of thermostat, doesn't audibly "turn on" right away. The burners fire up right away (which you can only hear if you're standing next to the furnace) and then the blower turns on some minutes later. In the summer, the Nest turns on the air conditioning unit right away.

Oh definitely, because I'm not just standing there waiting for it to turn on immediately. There have been times when we're freezing, and I tell my wife "just turn the temperature all the way up" and then she says "I did a while back" and when I go to check, it's on 90. So we're talking 20 mins having passed and the heating unit barely coming alive, when in reality it should be on the whole time attempting to heat up to 90.

  I had a similar issue, but it's because I had setup the nest incorrectly. It asked about my equipment and about my setup, and I got it wrong. So when it would try to turn on the heat it would not turn the blower on. Once I fixed the configuration error it works instantly.

    Thanks, I'll check this out. I had mine professionally installed, so I generally trust the company that did it, but always good to double check.

      I set mine up myself (easy setup was a perk I noticed when buying it a few years ago) and in the application, there are several details you want to fill out on initial setup. A big one is the type of heating/cooling you have in your house because it adjusts behavior in response. Over time it "learns" the quirks of your setup such as how responsive it is and adjusts to compensate. At least that's how it's supposed to work and how mine works. The "90 minutes" or "2 hours" or whatever it shows is supposed to be based on its estimate based on how it's modeled your house's hvac setup.
