What to Look for in the Best Programmable Thermostat under $100

Best Programmable Thermostat under $100

If you are searching for the best programmable thermostat under $100, then you are likely requiring simplicity and usefulness – all while sticking to a budget. Here is what you should be looking for:

  • Number of Programmable Days

The first thing that you will have to look for is over how many days this unit can be programmed. Let’s say that you are away five days a week, and are only home for two days, during the weekend. In this case, you might want to choose a programmable thermostat with a 7-day span.

Plus, some units allow you to program through times of the day as well. For example, if you are away for most of the day and only get home during the evening, then you may set the thermostat to only release warmth or cool air after 6 or 7 PM, for example.

  • Connection System

Before buying a thermostat, you need to make sure you have all it takes to hook it up on the wall. For example, some thermostats are simple and do not require any special wiring. On the other hand, there are those that require a C-wire to be installed – an operation that might require the help of a professional.

  • Display and Controls

How do you want the unit to be controlled? Do you want to go for a touchscreen model, or do you wish to go for a standard, button-pressed one? Bear in mind that touchscreen units tend to be more expensive, but at the same time, are a bit easier to use.

  • Extra Features

Can you access the thermostat through an app or a web browser? Or can you only use it by going to the thermostat itself? Maybe you want to connect it through Amazon Alexa, as it is always listening to your surroundings. You can easily find a useful thermostat at around $60 – but the more features it has, the more expensive it will be.

Wrap Up

Finding the best programmable thermostat under $100 is simple as long as you know where to look for it. The advantage of these models is that they don’t have any complicated features, making them quite easy to use. Still, even though they are not as expensive, it does not mean that they cannot be highly efficient at their job.
