What is the Most Reliable Smart Thermostat?

Today’s homes are becoming increasingly connected as further innovations within the smart technology industry are brought to market. These devices allow us a seamless and worry-free control-hub in which we can navigate and simplify our overall lives.

One of the leading smart devices on the market today is the smart thermostat. With all of the benefits they have to offer it is no surprise that the smart thermostat market is estimated to be worth a whopping 2.8 billion dollars by the year 2025. Some of the leading brands – Nest, Ecobee, and Honeywell, produce the most reliable thermostats on the market.


Every smart thermostat that I list below is made out of durable plastic designed to withstand years of contact with the touchscreen. The long-lasting materials used in construction not only look good, but it guarantees you have a reliable piece of equipment that will keep you and your home comfortable for years to come.

In today’s growingly mass-produced world, one may start to think that a reliable product is a thing of the past – something only our parents and grandparents know about. This cant be further from the truth when looking at the products that made this list.

From longtime crafters to the new guys, you can count on any one of these products or their neat features to improve your life and keep you feeling good.


Apart from being able to save a chunk of money on your energy bills, smart thermostats do offer additional advantages. From looking nice on the wall to offering insider tips on how to increase air quality, these thermostats can make more than just one aspect of your life better.


Many smart thermostats inform you about the temperature and humidity levels of the air outdoors. More than likely you walk past your thermostat at some point in the morning, so instead of sitting through the depressing news just for the forecast, you can get the 7-day rundown right there in your hallway.

Some thermostats, like the ones offered by Tado, even inform you about the quality of the air outside. It does this by projecting information, such as the pollen level, on the screen of the thermostat.

Air Quality

Many smart thermostats on the market today assist the user in ensuring the indoor air quality of their home stays at an optimal level. Aside from the saving money thing, this is by far my favorite thing the smart thermostat has to offer.

Maintaining healthy indoor air quality is important – especially in today’s world. We breathe enough harmful airborne chemicals in our day to day lives, why shouldn’t we be able to at least breathe clean air inside our own home?

Smart thermostats have the ability to detect the level of particulates inside the air in your home and they send you an alert when this level reaches an undesirable amount. You can then take the necessary steps in reducing the level of particulates, by circulating the air through your HVAC system.

Another air-quality advantage of the smart thermostat is that it will actually send you reminders on your phone for when you need to change the air filter. This is especially important if you are anywhere near as forgetful as me.


Smart thermostats require wi-fi in your home, and any existing smart hub devices you may have, be that Google Home or Amazon Alexa. While the smart hub is not necessary in order to have a smart thermostat, it does offer additional features such as voice control that you won’t have access to without.

While you can use your new thermostat without a smart hub, you cant access any of its features without a wireless connection. If you don’t have wi-fi then your smart thermostat isn’t going to be anything more than a fancy looking thermostat on the wall; you will still have basic temperature control, but you won’t be able to control it remotely or have access to any of the additional features.

Cost of Installing a Smart Thermostat

As with the installation of anything, there are different factors that play a role in the overall cost of installing a smart thermostat, and while it can be a sizable investment on the high end, I think you will be pleasantly surprised with how cheap installing one can be – especially if you do it yourself.


Installing a smart thermostat is actually pretty simple, and if you are comfortable with wiring a regular thermostat then you can handle the job with no problem. They wire up just like a regular electronic thermostat and require a c wire. Take a picture of how the old thermostat is wired before you start because they will connect to the respective terminal on the new thermostat.

  • Line the mounting bracket up on the wall. You may want to check it with a level – when satisfied with the placement mark the holes on your wall with an ink pen or screw.
  • Drill out the holes where you made the marks and insert some wall anchors to ensure a sturdy install.
  • If the hole placement on the mounting plates lines up with the previous holes then you don’t have to mark the holes and can instead go straight to screwing the mounting plate to the wall.
  • Pull the wires through the back of the mounting plate and screw it to the wall.
  • Referencing the photo you took of the old thermostat and how it was wired, you will need to connect the wires to their respective spots on the new thermostat.

If you have any trouble with the installation, and the installation manual that came with the thermostat is not helping – you may need to contact the manufacturer’s customer support line or a licensed HVAC technician.

Additional Costs

If you have to hire an HVAC technician or an electrician to come out and install the smart thermostat for you, then you’re going to end up spending more money on the overall installation – but with the extra cost comes the peace of mind in knowing that the job was done right.

The cost of the job will vary by company so it is important that you call around and get free estimates so you ensure that you are getting yourself the best deal on the job. You might also want to make sure it is a flat rate, as hourly jobs can get out of hand should they encounter an unexpected issue during the installation.

Now that you are aware of all the great benefits that a smart thermostat can offer you and your home it is time for me to go over some of the most reliable smart thermostats on the market today. After reading what follows you will be equipped with the product knowledge you need to confidently invest in a new thermostat for your home.
