Top Customer Reviews

I'm an HVAC contractor who's installed and troubleshooted this product in customer's homes for the past couple years and experienced the good, the bad, and the ugly. Let's start with the good.

Pros:

-It looks great. Personally I don't really care what my thermostat looks like but I know that is very important to many people and the Nest is unmatched in this area.

-When it works, it is hands down the easiest thermostat to install. The ability to sense wires and automatically configure the thermostat is a cool feature you don't see too often. They have a nifty wizard on their website that where you check the wires you have and it figures out what type of system you have and whether or not it will be compatible. Not that I really care, since this is what I do for a living, but for DIYers who have never done something like this before, it's nice.

-In theory, it can control quite a wide range of HVAC systems, including 4 stages of heating, 2 stages of cooling, dual fuel systems, and humidification/dehumidification.

-The customer service reps do genuinely seem to want to help, and there have been cases of them giving refunds even outside of the return period, or paying for visits by HVAC contractors to troubleshoot issues or repair damage caused by the thermostat.

-The auto away and auto learning seem to work as advertised for the most part and IF, a big IF, you didn't program your previous thermostat, they will save you energy. However your money would be put to much better use by spending 10 minutes reading the manual of your traditional thermostat and programming it (even if its unintuitive, it's not something you have to do often).

I received and installed my second-gen Nest thermostat about three weeks ago and was initially very happy with it. Simple to install, beautiful, easy to use, it is certainly all that. Unfortunately, it lacks one characteristic that a thermostat MUST have. It is not robust. It fails under circumstances that a $50 hardware store thermostat would have no problems with, and when it fails it DOES NOT FAIL SAFE - which is a pretty major problem when you're talking about a device that is controlling expensive heat and cooling (and, in a cold climate, keeping your pipes from freezing!)

I was pretty surprised to come home today to a sweltering-hot apartment when the outside temperature was in the mid-to-high sixties. It's a brand-new apartment, very well insulated, and initially I simply thought that all the sun streaming through the skylights and windows was responsible for the high temperature. The Nest indicated that it was 86 degrees inside and of course, with a set point of 50 degrees, it was obviously not heating. (Right?) I set the temperature to 75 and switched it to cooling mode. Cool air started streaming from the AC vents - great. Should cool down in a little while. (Right?) After thirty minutes with the AC on, I was if anything more uncomfortable, so I went over to the Nest again - imagine my surprise when I saw that the inside temperature had gone up to 89 degrees! At this point I knew something was very wrong. It took only a few seconds to determine that the Nest had my heating on full bore - even while the AC was cooling. No wonder the place was sweltering!

The manufacturer commented on the review below
As a certified licensed HVAC contractor for 32 years and Certified Nest Reseller in Scottsdale Arizona I have personally re-installed and troubleshot over 50 of the Nest thermostats. We like the Nest and it's concept though we have been experiencing multiple problems with regards to error messages, units operating erratic, systems switching from ac to heat, compressors cycling into internal overload, burnt up control boards and relays to name a few. I do admit it's great for business, though once we show up for service, we now own the call and are responsible for making the system work. The newest problem was this last week on a commercial building with 4 new AC units on the roof and 4 new Nests. We have logged in 6 additional non chargeable hours to troubleshoot and replacements in a 1hr job to change out all 4.
To keep it short, these are the facts;
*Installed 4 nests, all AC units are same brand, 2 Nests are functioning
*Nest #1, installed, ran for 1 day went into heat, troubleshot replaced control cable and determined bad base, replaced with new from supplier. Installed new Nest, ran 3 cycles, began chattering compressor contactor relay (shorted from 26v to 16v) and compressor went off on overload. Replace Nest with conventional thermostat, unit is now operational for last 2 days.
*Nest #2, customer wanted nest in his office, shut off system power, removed Nest head, relocated line in office, reinstalled base and applied power to system, Nest displayed error message on G terminal as no power and system had no fan, removed head metered lines and jumped fan circuit and fan came on. Replaced Nest with conventional thermostat, unit is operational.
