Buyer’s Guide

When purchasing a thermostat, it’s important to consider how each product’s design and features affect its performance. Here are three factors to think about before buying a thermostat.

Thermostat Type

Thermostats are generally split into three categories: smart thermostats, programmable thermostats, and non-programmable thermostats.

Smart thermostats are a popular choice for many homeowners because of their compatibility with other smart home devices and their ability to regulate your home’s internal temperature. Smart thermostats are usually controlled by mobile apps or voice assistants, such as Google Assistant or Amazon Alexa. Many smart thermostats also provide you with energy consumption statistics so that you can track how your home heats and cools itself. The drawback to smart thermostats is their price, which usually far exceeds programmable and non-programmable models.

Programmable thermostats are convenient because they let you set a specific heating and cooling schedule based on the time or day of the week. You set this schedule using the buttons and switches on the thermostat’s body.

Non-programmable thermostats are basic models that allow you to set your home to your desired temperature. These thermostats are mostly limited to showing you the current and set temperatures. However, the benefit of these thermostats is their affordable price.


Before picking a thermostat, look at its installation process to decide whether to enlist professional help or complete it yourself. While installing a thermostat on your own can seem daunting, most modern thermostats require few tools and include step-by-step instructions.


Your thermostat should have an easy-to-read display so that you know your home’s current temperature and your thermostat’s current settings. Most smart thermostats include a backlit display for viewing the temperature in low light.

Frequently Asked Questions

How does a thermostat work?

A thermostat sends a message to your heating and cooling system based on the temperature you set it to. For example, if you set your thermostat to 72 degrees Fahrenheit, the thermostat will turn your system on when it’s higher or lower than this temperature.

How do you know if your thermostat is broken?

If your thermostat won’t turn on or is unresponsive, this may signal a problem. Additionally, if your air conditioner or heater won’t turn on or is running when it shouldn’t, you may have a faulty thermostat. If you’re unsure if you have a problem, call an HVAC professional.

Where is the best place to put a thermostat?

The best place to install a thermostat is on an interior wall of your home. If you install your thermostat on an exterior wall, the thermostat’s internal thermometer might be influenced by the temperature outside, which can cause your HVAC system to run unnecessarily.
