Materials
The most important thing that you should take into consideration is quality.
There are many ways that you can do to determine if the model that you like is a high-quality product. The quality of the product can be checked through its build. Most of the time, good quality products are made of high-quality materials. Another thing that you can do is to check the aesthetics of the product.

No matter how expensive the product is if it is not compatible with your HVAC system, it is still useless. Compatibility should mean that the product should seamlessly work well with your heating system and your air conditioning system. There are other brands that can work well with gas, oil, and electric HVAC. Several others are only limited to a number of systems.
Another thing that you should take a good look at is if you are using a multi-stage heating and air conditioning systems. You have to know if the product that you like supports this setup. There are brands that can support a couple of stages. There are others that can back three stages and some other support more.
C-wire Requirement
The majority of the thermostats in the market today entail much electrical power more than a pair of batteries can produce. Luckily, they do not really require so much power than necessary to be placed into the wall. Instead, they depend on the low-voltage power supplied by your HVAC system. Some of the models of the latest thermostats today require a dedicated C or common wire.
Although some brands can suck power from an alternative source, this practice is often the cause of some issues with the HVAC system that includes long-lasting damage. If you wish to have the best smart thermostat and you found out that you have no C wire, it is best that you install one. While it is not required, most manufacturers highly advise to utilizing one.
Home System Integration
Most of the models nowadays are equipped with an application so you can manipulate it using your tablets, smartphones, and other mobile devices. However, the best smart thermostat models are those that can be integrated with other home devices and home systems. Aside from controlling temperature, it can also integrate with digital assistants like that of Google Home or that of Amazon and use a voice command to adjust the temperature. It can also be linked to the smoke detector or include IFTTT support.
Ease of Use
The days where the user interface of a thermostat is consists of numbers are long gone.
A good device should help you understand crucial information in a jiffy and could easily adapt to your needs.
Another crucial factor that you should consider in choosing is that it should not be hard to install. Look for the model where the manufacturer provides all-inclusive but easy to understand guidelines and instructions that include photographs and illustrations to help you through the entire process. The product itself should plainly indicate the wires and where they should be placed. There are companies that put labels on these wires so you can easily attach them to the wires in the wall as you remove and disconnect the old thermostat. It is also important that the wires are color coded. Some users take a picture of the old model to use it as a reference before removing it.
Style
This factor is not really important if you are the type that is not very particular with the design.
However, if you want to make the most out of your money, picking a well-designed product is a way to. You can choose a design that could complement the motif of your home so it would not look out of place. In choosing a design, it is also important that it does not only look good but it is also functional.
Among the design considerations that you should factor into includes a great display. The latest models now have digital displays. The display should be easily readable or visible even if you are from afar. It would also help if it comes with a backlight so you can still clearly see it even if the lights are off.
Another important design consideration is the controls. The controls should be easy to use so you will not have a hard time controlling your desired temperature. The mount should also be durable and could be easily affixed on the wall. It should also be secure so you will not wake up with your thermostat on all broken on the floor.
Advanced Features
One of the reasons why you would like to acquire the best thermostat is because you are fascinated by its features.
These features include connectivity to Wi-Fi, compatibility with virtual assistant devices and other voice operated platforms, and automatic functionalities. Other features include the ability to learn new routines, and programmability. There are brands that can support more than one voice control device.
Geofencing
This particular feature utilizes the app of the thermostat and the GPS of your smartphone to build a border around your home or workplace. When you are away from that established perimeter, you no longer need heat or cooling. Geofencing enables you to adjust the temperature of the place to prevent itself from operating unnecessarily. As soon as you reach the perimeter again, your HVAC system can spring into life so you will feel cold or hot or comfortable when you arrived home.
System Complexity
Another important feature that you would want to consider is its system complexity. The list of products included in this guide support HVAC systems, heat pump systems, and multi-stage heating. If your homes are built on different zones that are either cooled or heated separately from each other, you will need a thermostat for every zone. This multiple zones could be easily controlled by a single app.
Remote Access
The remote access feature of a thermostat allows you to manipulate the temperature of your home or workplace even if you are far from the actual place. You can adjust or check the level of temperature wherever you are in the world as long as there is an internet connection.
Sensors
While Geofencing is good, it is only functional if everyone who is residing in the place has a smartphone. Another feature that many users like about this new breed of the thermostat are their sensors. These radars provide another way to determining if you or a family member is at home. The first thermostat from Nest was heavily criticized because it depends so much on the motion sensors. Several models have the capacity to use windows, doors, and motion sensors for the home’s security system. There are also others that are equipped with proximity sensors. This triggers the thermostat to turn on its display when someone walks past it. Some users use this as a light to their pathway during night time.
