Let us go over the rest of it down below.

Why Do You Need To Replace Your Old Thermostat?

Thermostats have a lifespan of 10 years on average. During that time, your thermostat may get damaged enough that you will have to replace it. The following are some signs that you need to replace your thermostat:

  • Faulty readings on the thermostat
  • The system keeps turning on and off on its own
  • Continuous changes in temperature
  • Utility bills are going high for no apparent reason
  • The thermostat is not responding to the changes in the settings
  • The thermostat’s lifespan is over
  • Your HVAC system is short-cycling

Steps To Choosing The Right Thermostat For Your HVAC System

Now, let us discuss the steps involved in the process of buying and installing a new thermostat:

Step 1 – What Type Do You Want?

You first need to see what type of thermostat you want for your HVAC unit. You can choose from various types of thermostats out there. The following are some of the main categories:

Programmable Thermostats

A programmable thermostat is one that automatically adjusts the temperatures throughout the day. These kinds of thermostats are quite efficient as they can be programmed to switch off when no one’s in the house. The thermostat will lower or increase the temperature by itself, so you do not have to worry about it.

Manual Thermostats

As the name suggests, these old thermostats need to be controlled manually. Although there have been many developments with thermostats since the manual one, these are still pretty popular as they are ideal for people who prefer fixed temperatures and are often at their homes.

Learning Thermostats

Learning thermostats are also known as smart thermostats. These are programmable, but you do not have to program them yourself. As you use them, they learn your preferences with the HVAC system and create a schedule that caters to them. These are the most advanced thermostats. They can also be controlled remotely with wi-fi.

Remote Thermostats

These thermostats can be controlled remotely, as the name suggests. You can connect them with wi-fi and then control the settings like mode, temperature, and such from your mobile, PC, tablet or any other smart device. 

Digital Non-Programmable

This is quite like the manual thermostats, as this is a non-programmable type of thermostat. But unlike the plain old manual thermostat, you get a digital screen here for the various settings. Since this is non-programmable, you will have to change the setting manually.

Those were the main types of thermostats for you to choose from. Do keep in mind to only go for the one that is perfectly compatible with your HVAC system.

Step 2 – See What Works For Your HVAC System

The next step in the process is to figure out what thermostat will work with your HVAC unit. This is very crucial, as getting a thermostat that does not work with your unit is as useless a purchase as any. Following are some things to keep in mind while narrowing your options down to the thermostats that are fitting to your unit:

Your System’s Voltage

The first thing you need to check is the voltage of your system. Cross-check that with the options available for you.

The Location Of The Thermostat

You also need to check if the new one will fit in the spot of the old one so that you do not need to get any rewiring done.

The Stages Of Cooling And Heating Your System Have

The last thing to check in the thermostat you are interested in buying is whether its wiring is compatible with the number of stages your HVAC system has for cooling and heating.

Step 3 – Get It Installed

The last step in this process is getting the chosen thermostat installed. Although this may seem like something that is all too easy, you must not take this step lightly. A slight malfunction could be a big problem later that could require not only repair for your thermostat but also your HVAC system.

So, you should only lean on professionals like us for thermostat installation in your home. This way, you can be sure that there will be no problems involved in the case.

Features To Look For In A Thermostat

Before you settle on a thermostat for your HVAC system, the following are some features you should look for in a thermostat:

  • App control
  • Voice control
  • Geofencing
  • Automatic changes in temperature
  • Relevant reminders
  • Ease of use
  • Intuitive controls
  • Auto changeover


That was all for a comprehensive guide to buying a new thermostat for your HVAC unit. We went over the reasons why you’d need a new thermostat, how to choose one and what features to look for in it.
