Saving money has never been more important for most Americans, yet many forget how much they inadvertently waste through inefficient heating and cooling of their home. According to the Environmental Protection Agency, you could save up to $180 per year on your energy bill simply by upgrading an outdated thermostat to a programmable model. Newer models keep track of daily activities, lowering the energy output when you’re sleeping or away from home, so you don’t pay to heat or cool a space to optimum temperatures around the clock.
These modern marvels include 7-day scheduling options, clear digital displays, touch screens, and programmable default settings that let you quickly return the thermostat schedule to preferred selections. Some programmable thermostats connect to smart-home devices, like Amazon Alexa and Google Assistant, allowing them to learn from each other and design a comprehensive heating and cooling schedule that suits your family’s specific needs.
Keep reading for a primer on what to consider when shopping for these eco-friendly devices, and discover some of the best programmable thermostats for the home on the market today.

What to Consider When Choosing the Best Programmable Thermostat
There are several factors to weigh when choosing the best programmable thermostat for your home. Be sure to consider compatibility with your current HVAC system, scheduling options, ease of installation, the ability to connect the thermostat with smart devices, and the desire for extra bells and whistles. Read on to learn more.
HVAC System Compatibility
Whichever programmable thermostat you choose, it must be compatible with the home’s current heating and cooling (HVAC) system. The first item to verify is if the system is low voltage (24V), which is true of most heating and cooling systems, as opposed to line voltage (120V to 240V). In a low-voltage system, a single thermostat controls a large furnace that heats the entire house. In a line voltage system, a thermostat controls an individual electric space heater, such as a baseboard heater, with each requiring an independent thermostat.
For quick reference, both ecobee and Nest offer compatibility checkers; or you can check out this detailed guide on furnace compatibility.
Next, determine if you have enough wires for a programmable thermostat.
- In low-voltage systems, the same wires all run to the thermostat from the furnace, so you won’t have to worry about wire type. Just keep track of the terminal letter to which each wire is connected.
- High-voltage systems have four wires: two that correspond to line terminals and two that connect to load terminals. When connecting a programmable thermostat, be sure to label all wires before detaching them from their terminals so you know where they reattach.
While not an issue for programmable thermostats without Wi-Fi, most WiFi-enabled programmable thermostats require a closed circuit between the furnace and the thermostat, using a common wire (also called a C-wire).
To tell if there is a C-wire, remove the cover from your current thermostat, and look for the terminal labeled “C.” If there is a wire here, you’re good to go; if not, check in the insulation behind the thermostat, as the HVAC technician who installed the unit may have buried the C-wire if it wasn’t immediately needed. However, only check inside the furnace for the correct wire if you are highly confident in your HVAC knowledge.
If the current system doesn’t have a C-wire, consider hiring an electrician or HVAC technician to run one from the furnace to the thermostat.
Programmable thermostats offer several scheduling options, which help save money by conserving energy whenever possible.
- Basic thermostats offer day and night modes that automatically lower or raise the temperature depending on the time of day.
- 7-day thermostats schedule an entire week, with a different program for each day that’s geared to when family members are home and when they’re away.
- 5+2-day thermostats have two weekly programs, one for the Monday to Friday work week and one for the weekend. 5-1-1 thermostats offer similar scheduling options, except the two weekend days can be scheduled independently.
Alternately, smart thermostats learn weekly patterns and auto-adjust without users having to create schedules manually.
Readable, Wireless Control, and Intuitive Design
How you read, schedule, and control the thermostat, either via a simple illuminated display screen or a fully integrated smart-device system, depends on your personal preferences.
The best programmable thermostats provide an easy-to-read digital hub where users can check the temperature in the home and schedule changes that match routines to adjust for when the house is empty versus full.
The latest styles trend toward a large, simple display on a wall-mounted touch screen. If you spring for voice control and compatibility with smart-home systems, you’ll be able to make scheduling changes without touching the thermostat.
WiFi-enabled programmable thermostats may also display temperature and scheduling options through coordinating smartphone apps. These wireless controls allow for operation of the thermostat outside the home, which is a convenient feature if you forget to adjust the temperature before leaving for the day. They can also send alerts to your smartphone about heating and cooling patterns.
Ease of Installation
A professional HVAC technician or electrician installs programmable thermostats, or you can do it yourself in about an hour if you have basic electrical skills, such as those required to replace an electrical outlet. Before buying a programmable thermostat, review the instructions on the product website to understand what is involved in the installation and determine if it’s a project you can handle alone.
Programmable thermostats offer a range of additional features. Some provide geofencing technology that uses an invisible perimeter around a specific geographic location (i.e., your home) to determine when you arrive and depart. Others have additional room sensors for more precise temperature control. Built-in programs, like Amazon Alexa, can turn a simple thermostat into a fully operational voice service that is capable of accessing the internet and retrieving weather, music, phone calls, and more.

The thermostat will record these settings and “learn” from them, which essentially means compiling the data and creating a customized heating and cooling program to meet the users’ needs.
To use voice commands, integrate the programmable thermostat with a compatible smart-home system, like Google Assistant or Amazon Alexa. Users can set the thermostat with customized schedules that change every day, depending on personal preference, or leave it on the auto function to adjust the temperature according to the learned patterns. It also works with popular smart-home systems, like Apple Home Kit or Samsung SmartThings, as well as supporting applications like IFTTT.
- Operates with voice commands, mobile app, or touch screen
- Learns preferred temperatures and programs itself
- Automatically adjusts temperature if you’re home or away
- Easy installation
- Occasional issues connecting to Wi-Fi
Every room of a house has a different ambient temperature due to insulation, exterior walls, and ventilation.
