Things to Consider Before Buying a Thermostat

Though these devices may easily fit into our pockets and be held in our palms, they do possesses several features that can either make it the finest smart thermostat that you have ever gotten or the most awful. So how do you distinguish between these features? What to prefer and what not to prefer? Read below and find out!

The setup of your existing HVAC system and the thermostat

The initial thing to assess while buying a smart thermostat is the kind of HVAC system it supports and if it requires a c-wire for its operation or not.

1. Heating, Ventilating, And Cooling (HVAC) System

The kind of HVAC system will predominantly control the unit you will purchase. While some models support multi-stage systems, others support only single-stage systems.

2. C-wire

One of the main difficulties that you will face while buying a smart thermostat will be the type of power source it acquires. Many units require more power than a pair of batteries can give. So you cannot use power batteries. However, they also cannot be connected to a power source as that will most certainly overheat or overload the device. So how does this small unit get its energy?

Through the HVAC system! The c-wire or the common wire is a small wire which is connected to the system. It provides the thermostat all the voltage it requires to function properly.

You might also come across some thermostat models that have an r-wire (power wire). This type of wire uses a secondary source to provide the device with the energy it needs. However, r-wires are less efficient than c-wires –It can also cause permanent damage to the HVAC system.

So before mounting a thermostat, look at the wiring your existing thermostat has. If you cannot locate a c-wire, you should get one installed before buying a smart thermostat. It will make your job much easier.


These days, thermostats come in diverse shapes and dimensions. Some possess an LED screen that has buttons on either side, while others include a huge display touch screen. Though this is an individual inclination, you might want to check out the size, visibility, and touch/button response of the display.

You need to ask yourself several questions -Can you effortlessly read all that the screen displays? Is it discernible? Does it possess a night-mode? How responsive and how easy it is to use the buttons on the unit?


One of the chief reasons why people have started to switch from their ancient manual thermostats to the innovative smart thermostats is the freedom; the freedom to control the device from anywhere and at any time! All you need is a smartphone that has installed the brand’s official mobile application. That is it.

So while making a decision, check out if the unit can be easily controlled. You can judge this by whether it has mobile accessibility, automatic features, and if it can be managed using Siri, Alexa, or other virtual assistants.

However, different models support different types of operating systems so make sure to read the user manual to find out if the device you have chosen can work with your phone or not.

Installation Process

Some thermostats come with a comprehensive and easy to understand user manual while others do not. Some even come with labeled wires so you know where each of them goes. Make sure that you read the instructions and user’s experiences to get a picture of how easy or complex the set-up process is.

Though, if you do struggle with the installation process, you can always call a professional right away and have them set it up for you. Make this call if you do not mind spending money after-purchase.
