A thermostat lets you lot control a dwelling's climate past connecting it to the heating and/or cooling systems. Whether it's an analog slider or digital push buttons, a thermostat allows you to conform the temperature for heat and/or cooling.

Thermostats are, from a user'southward standpoint, relatively uncomplicated, straightforward instruments. To increase or subtract the temperature of a room, you simply turn a dial or move a slider to a temperature range or basic settings for cool, hot, or off.

Simply they can also exist complex. Many thermostats today are smarter and actually require little interaction from our part. Some tin can be programmed to operate on a schedule, while more than advanced, "smart" thermostats tin can be controlled from a smartphone or even learn your household's daily habits and accommodate the temperature automatically. These advanced thermostats let you tune into the exact temperature. Yep, there is a big difference between 65 and 70 degrees Fahrenheit — just inquire whatever dad.

The best overall

Amazon

The Google Nest Thermostat East has an impressive set of high-end features and a mid-range cost tag.

The Thermostat Due east (T4000ES) is Google Nest'south affordable offering but information technology offers much of the same outstanding functionality as the Learning Thermostat, Google Nest's flagship and pricier model.

Performance-wise, the Thermostat Eastward operates similar the Learning Thermostat. For the lower price, you lot don't get color options (it comes in just white), it'southward made out of plastic instead of metallic, it has a lower resolution display that isn't sharp (information technology's harder to read, especially from a distance), and it's compatible with 85% of HVAC systems (compared to 95% for the Learning Thermostat). Yous besides can't pull up the time or weather on the display, as you tin on the higher-stop model.

However, every bit long as your HVAC system is uniform and you lot can practise without the frills, the Thermostat E offers the same groovy smart functions as its sibling including remote command, auto temperature adjustment, and the power to learn your household habits and arrange the climate appropriately. We also don't think the white plastic looks bad; in fact, subjectively, we think it'south sleek-looking.

All you need to command your dwelling house's HVAC system is the feature-rich Nest App. From installation to making adjustments while in bed or out of town, the app makes it easy to salvage energy. To simply plough the temperature up or downward, you can also just turn the dial on the unit itself.

In the app, you tin set a unproblematic schedule that adjusts the temperature based on your comfort and habits. The thermostat will accommodate to a more energy-saving temp when you get out. The app's free energy history provides useful data about your energy employ and what y'all tin can do to salvage money. And, Nest'due south unique learning power makes adjustments based on your preferences.

Pros: Attractive appearance, easy to install, learns your preferences and adapts, adjusts the temperature based on whether you're habitation or away, outstanding app

Cons: Display can be hard to read, limited compatibility with not-Nest smart dwelling house devices

How to install a Nest thermostat

The best non-programmable

Amazon

If y'all don't need the bells and whistles of a smart thermostat, save yourself hundreds of dollars with the Honeywell Digital Not-Programmable Thermostat.

While we are big fans of smart thermostats and believe they pay for themselves in free energy savings, you might prefer to avoid the hassle of using an app or programming your thermostat. For an affordable, barebones workhorse, the Honeywell Digital Non-Programmable Thermostat (RTH111B1016/E1) should go the job done.

The Honeywell Digital Non-Programmable Thermostat is simple to use. Just two buttons allow yous adjust the setpoint and there are only 2 switches, one for heating and cooling and another for turning the fan on or setting it auto. That'south it. Installation is every bit unproblematic, and because information technology doesn't have any complexity, it should be reliable.

I drawback is that the Honeywell Digital Non-Programmable Thermostat does not work with electric baseboard or estrus pump systems.

Pros: Like shooting fish in a barrel to read display, affordable, intuitive operation, simple installation, maintains temperature if the power goes out, nifty for rental backdrop

Cons: Not programmable, incompatible with electrical baseboard or heat pump systems

The best with Alexa

Amazon

The Ecobee SmartThermostat with Voice Control not only has an outstanding app and intuitive programming, just it also has built-in Alexa and a speaker with proficient audio quality.

What sets the Ecobee SmartThermostat with Phonation Command apart from other smart thermostats is the born smart speaker. Essentially, it'due south a hybrid device that combines a thermostat with Amazon'southward Alexa smart assistant for vocalism calling, messaging, music streaming , and more.

The SmartThermostat comes with a sensor that measures temperature readings wherever it is installed. The thermostat and then adjusts the heating and cooling based on the reading and whether the room is occupied. Yous can purchase boosted sensors, too.

Though I had some initial problem getting the SmartSensors to connect — a bug that Ecobee has since fixed — I've found they are accurate and do a cracking job of regulating the heat in my large, drafty house. After a little tinkering, the temp controls are fully-automatic; I rarely need to brand adjustments to the schedule.

The voice control is a squeamish luxury, just for me, it'south more of a novelty. It's fun to tell the SmartThermostat to communicate to a robotic vacuum that I want it to start cleaning. I'one thousand more beholden of the speaker, though. My thermostat is located in the dining room, and it'due south great for background music during dinner.

Pros: Integrates into the near pop smart home system, user-friendly app, speakers that really sound decent, built-in Alexa, dual-ring WiFi

Cons: Problem connecting SmartSensors, not compatible with all HVAC systems

What else we considered

All-time Purchase

While researching this guide, nosotros considered many thermostat models, and almost included many of them. These five are high-quality options that just missed the cutting:

Google Nest Learning Thermostat (Third Generation) : The Learning Thermostat was our previous top choice, and there's a lot to like nearly information technology. Information technology has several of the same benefits as our top pick, including geofencing and compatibility with Alexa. However, we chose non to include it because the Thermostat E offers similar functionality for less money. We also constitute heir-apparent complaints about it malfunctioning and causing homes to dip to dangerously low temperatures.

Lux Programmable 5-2 Twenty-four hours : This is some other model we previously recommended. We similar it because it's an affordable programmable non-smart option and its unproblematic blueprint makes it easy to use. But we dropped it because we think the Orbit Articulate Comfort is more visually appealing, and the Lux has quality control issues. Specifically, the unit of measurement will flash low battery, even after installing fresh batteries. Fortunately, a factory reset unremarkably fixes this problem.

Aprilaire 8600 Programmable Touchscreen : This thermostat because is two-wire compatible, allows y'all to program heating and cooling schedules simultaneously, and has a touchscreen. However, other than the touchscreen, we didn't see any reason to include it in our guide over the Orbit Clear Condolement, which costs less.

Honeywell RTH8560D1002/E T5 Touchscreen : This non-smart programmable thermostat has intuitive programming that allows you to schedule heating and cooling at the aforementioned fourth dimension. The display is easy to read and impact-enabled. Plus, the layout is convenient. But there are heir-apparent complaints about inaccurate temp readings.

Lennox 13H14 Comfort Sense 7500 Touchscreen Multi Phase : This non-smart programmable thermostat is unique in that it tin handle multi-stage HVAC systems. It'southward easy to set-upwards and program, has an attractive high-contrast display, and performs well. All the same, it requires a C-wire to operate, doesn't offer holiday settings, and is more than expensive than many smart thermostats that take better features.

What we look for in thermostats

Whether testing thermostats firsthand or evaluating other reviews, there are a few performance metrics and features nosotros look for. Here are the most important attributes:

Installation: Being able to install a thermostat without enlisting the help of a professional can save you hundreds of dollars. So, the unit must be easy for even the novice homeowner to install in minimal time. The thermostat shouldn't crave yous to have whatsoever specialized tools on mitt and should come up with unproblematic-to-follow step-past-stride instructions. (There are exceptions, like when you need to take a C-wire installed)

Compatibility: We won't recommend a thermostat that only works with one blazon of HVAC system; this isn't useful for virtually buyers. Instead, we look for models that piece of work well with a broad variety of systems. Still, take a moment to read the production folio to double-bank check that a thermostat will work with your HVAC system and wiring. And, make sure y'all take the option to return the product if you end up ownership a thermostat online that isn't compatible.

Programming: A smart mode to relieve on energy costs is to turn down the heat or AC when you are sleeping or abroad from abode. Since most homes are empty during the mean solar day while occupants are at work or school, you want to be able to schedule your system to regularly switch to less comfortable, more eco-friendly temps at these times, and switch back an hour or and so before the family unit gets home. Therefore, if you choose a programmable thermostat, it must offer options that fit your lifestyle.

Performance: A thermostat should practise what the manufacturer says it can practice, and do it well, such as maintaining accurate temperatures. In the instance of smart models, the unit of measurement must maintain a Wi-Fi connexion and the companion app needs to part seamlessly. With programmable units, the setpoint should accommodate at the precise time you lot want information technology to.

Readability: You lot desire to exist able to glance at the thermostat from across the room to hands run across the current temperature and whether it's currently heating or cooling your domicile. When programming the device, it should exist easy for you to come across what you're doing.

Smart features: If you're going to pay top dollar for a smart thermostat, you'll desire as many smart features as possible. Look for geofencing, extreme temperature alerts and other notifications, intuitive app command, smart home compatibility, and even learning and automation.

Since there are so many similar models, continue a close eye on the model number to make sure yous're getting the thermostat you desire.

Types of thermostats we considered

Non-programmable thermostats come in two varieties: mechanical and digital. You volition need to manually adjust the setpoint for these, and in that location's usually a switch for alternating between hot, cold, and off. Y'all can find either for less than $xx. Digital units require a power source, while mechanical thermostats practise not. Mechanical thermostats are notoriously inaccurate in their temp readings, so nosotros didn't include any in our guide.

Starting at around $40, programmable thermostats allow you to ready a schedule, and some even let you set abode/away and vacation preferences. Some programmable thermostats are battery-powered, so the device volition keep operating if your home loses power (though your HVAC system probably won't).

Smart thermostats are the newest iteration. You tin unremarkably install one on your ain using in-app footstep-past-step instructions. A touchscreen and user-friendly interfaces make programming simple and some models have "geofencing," which can sense when you are abode or non and adapt your temperature settings for optimal energy utilisation. If they are Wi-Fi-enabled, you lot can also control the thermostat remotely. Working in conjunction with a smartphone app, yous can track your energy use and follow toll-cutting tips. The best smart thermostats also work with room temperature and occupancy sensors to ensure that occupied rooms are at the preferred temp, and they back up voice administration and smart home ecosystems.

But smart thermostats tend to exist two or three times more expensive than the alternatives. You also typically demand a C-wire, or common wire, to install the thermostat yourself, which provides continuous power to the thermostat.

My house is quite old, then when I upgraded to a smart thermostat, I had to beat out out hundreds of dollars to have an HVAC contractor install the C-wire. Still, factoring in energy savings, this might be an selection worth considering. If you are strictly looking for smart thermostats, nosotros have a separate buying guide devoted to them.

While researching thermostats, we looked at hundreds of buyer and expert ratings and reviews of countless models. Our guide features units that have a track tape of accurate performance, high-dissimilarity displays that are easy-to-read, and effortless operation.
