  • Energy savings - How much will you save on your monthly energy usage with the thermostat? We look for products and devices that carry the ENERGY STAR seal for the most-efficient products.
  • Installation - How long does it take to install the thermostat? Is it DIY or does it require professional installation?
  • Price - How much does the thermostat cost and how does that pricing compare with any potential savings on your energy bill?
  • Learning capability - Does the Wi-Fi thermostat learn your routines and preferences automatically, or is it programmable?
  • Warranty - Does the brand offer a warranty on the thermostat, and if so how long does the warranty last?

Honeywell T10 Pro Smart Thermostat

Honeywell

Honeywell T10

The T10 Pro Smart Thermostat is one of the more popular offerings from Honeywell. It is a touch-screen smart home thermostat that helps provide energy savings and by working with their RedLINK Room Sensors to detect motion and focus heating, air conditioning, ventilation, and humidification in occupied rooms.

Why buy - The Honeywell T10 has been shown to reduce pockets of warm and cool air that can make for uneven air distribution. Installation is very easy so long as you have a "C" wire connection. For ease of use and consistent energy-saving functionality, the Honeywell T10 is an excellent option.

$180

Price - Through Honeywell, the T10 Pro Smart Thermostat requires you to contact a pro for pricing. Through third-party retailers like Amazon, however, the thermostat is priced around $180. Compared to the Google Nest and ecobee SmartThermostat, this is a slightly cheaper option to provide energy savings for most modern HVAC systems. There are some third parties that offer installation, which can increase the total price to $239.00.

Warranty - All Honeywell products come with a manufacturer warranty of 24 months. The warranty can be determined by the product date code. The only exception to the 24-month period is the hardwire contacts with comes with a 5-year warranty. The warranty covers defects in workmanship under typical use.

How it works - The Honeywell T10 works with most modern HVAC systems to make energy usage more efficient during heating and cooling. This is achieved through programmable scheduling, which ensures that the HVAC system is running only when it needs to be. Traditional HVAC systems may have fans that run continuously, raising energy costs along the way. The T10 Pro works with Honeywell's RedLINK sensors and the Honeywell Home app to learn your routine so it can adjust energy use to be more efficient.

Mobile app - You can control Honeywell smart thermostat with the Honeywell Home app. The T10 Pro Smart Thermostat works with the app's geofencing capability to detect when you are out of the house to reduce energy usage. The app also allows you to remotely adjust the temperature and provides alerts about temperature changes or when it's time to change the filter. The T10 also features compatibility with Amazon Alexa, Google Assistant, Cortana, and IFTTT.

Energy savings - The Honeywell T10 thermostat is ENERGY STAR certified. That means it has met the stringent standards required by ENERGY STAR to ensuring that energy usage is reduced for greater energy-saving capabilities. This can vary based on home size and HVAC system.

Installation - Like most smart home thermostats, the Honeywell T10 can be installed by a professional or can be done as a simple do-it-yourself project. Those looking to perform a DIY installation can expect it to take around 30-45 minutes from start to finish.

Honeywell T9 Smart Thermostat

Honeywell

Honeywell T9

There are a lot of similarities between the Honeywell T9 and T10 Pro, making it difficult to determine the true difference at first glance. There are a couple of important distinctions, however, between the two that make the difference. The T9 thermostat works with Honeywell Smart Room Sensors to help customize your energy usage for different rooms in your home.

Why buy - The differences between the T9 and T10 are minimal. The former comes with a C-wire adapter for easier installation while the latter does not. The T10, however, controls ventilation, humidification, and dehumidification whereas the T9 does not. For easier installation and a lower price, but more limited features, the T9 is your choice.

$175

Price - The T9 is slightly most cost-effective than the T10. Ranging between $140 and $180 depending on where you buy it, it is slightly cheaper than the T10. For those looking to get the smart thermostat experience without paying more than $200, the T9 makes for an excellent option.

Warranty - All Honeywell products come with a manufacturer warranty of 24 months. See the details on the warranty in the T10 Pro review for more information.

How it works - Like the T10, the Honeywell T9 uses touch screen functionality, a Wi-Fi connection, and the brand's smart phone app to provide convenience and home energy-saving capabilities. Users can complete the initial setup and then create custom heating schedules that fit their needs, cutting down on energy usage along the way. You can also install Smart Room Sensors that will allow the thermostat to adjust temperatures based on your routine. Best of all, it is meant to fit most current HVAC systems for ease of installation.

Mobile app - Using the Honeywell app, which is compatible with a variety of Honeywell smart thermostats and devices, users can create custom heating and cooling schedules with just a few taps. It also allows you to check current temperatures, access the features and settings remotely, and more. Initial setup is done on the unit itself but it can be controlled remotely from that point on.

Energy savings - The Honeywell T9 is also ENERGY STAR certified. That means you can use the T9 thermostat to make more efficient use of your home's energy and see savings on your bill each month. Pair with Smart Room Sensors for optimal performance and efficiency.

Installation - Like the T10, the Honeywell T9 can be installed either by a professional or as a do-it-yourself project. There are some third-party retailers that will offer installation as part of the price. Those looking to perform the installation on their own can expect a 20-30 minute installation as the "C" wire comes with the unit.

Honeywell T5 7-Day Programmable Thermostat

Honeywell

Honeywell T5 Programmable

It may seem that all smart thermostats are created the same. There are, however, some more basic options meant to deliver energy-saving functionality at an affordable price. The Honeywell T5 programmable thermostat can help you use energy more wisely with its smart response learning feature that allows it to remember your temperature preferences so it can adjust automatically.

Why buy - Those looking for simplicity in their smart thermostat without breaking the bank will like the Honeywell T5. It offers learning capabilities and a large, bright display that makes it easy to program. Despite the lack of a smart phone app, users can create custom schedules in no time.

$60

Price - The Honeywell T5 is much more cost-effective than the T9 and T10. Officially priced at just over $75, it can be purchased through third-party retailers for as little as $60. Compared to $150-$200 of some smart thermostats, it is one of the more cost-efficient options on the market.

Warranty - All Honeywell products come with a manufacturer warranty of 24 months. See the details on the warranty in the T10 Pro review for more information.

How it works - The Honeywell T5 has a basic backlit display that allows for setting the time, showing current temperatures, and even showing the temperature set point. The T5 also learns heating and cooling run times for proper scheduling.

Mobile app - The downside to the T5 is that it does not have remote access. There is no app functionality for the T5 and all programming and changes must be done at the console. Because it is more cost-effective than some of the other Honeywell thermostats, it is missing the ever-popular remote functionality.

Energy savings - Though the Honeywell T5 is not ENERGY STAR certified, there are energy-saving capabilities. Factoring in size of the home as well as the age of the HVAC system, you can still save up to 10% annually on your heating and cooling bill with a programmable thermostat.

Installation - The Honeywell T5 comes with standard mounting hardware and a quick install guide. Users can expect about 30 minutes of installation time for even the most novice of users.

Honeywell Wi-Fi Smart Color Thermostat

Honeywell WiFi

Similar to the T10 in a lot of ways, the Honeywell Wi-Fi Smart Color Thermostat has a few distinct differences. This thermostat features a touchscreen with customizable full-color display and works with the Honeywell Home app, Amazon Alexa, and Google Assistant.

Why buy - This is the Honeywell smart thermostat with all the bells and whistles. Users can set custom schedules, control settings, and do just about anything else through the smart phone app. It also features custom learning, picking up on heating and cooling schedules accordingly to maximize your energy efficiency.

$129

Price - The Wi-Fi Smart Color is similar in price to the T10, officially listed at $170. You can find it through third-party retailers for around $130. Combined with installation packages from third-party retailers, users can expect a price tag of around $229.99 with installation included.

Warranty - Though most Honeywell products have a 24-month warranty, the Wi-Fi Smart Color thermostat only has a 12-month limited warranty. It is meant to cover against manufacturer defects and issues arising from regular usage.

How it works - The Wi-Fi Smart Color has a big, beautiful color touchscreen display. Users can program a variety of 7-day schedules, set time and temperature, and just about anything else from the bright panel. It works with your home's current HVAC system to properly manage heating and cooling schedules for greater energy savings, and its smart response technology lets it automatically adapt your energy use to your schedule.

Mobile app - The Wi-Fi Smart Color thermostat makes use of the Honeywell Home smart phone app. Users can program 7-day schedules, adjust current temperature settings, change modes, and control the fan all through the smart app interface.

Installation - As is the case with other Honeywell smart thermostats, both professional and DIY installation are available. With the quick install kit, users can conservatively expect 25-30 minutes of installation should they do it themselves.

Additional Honeywell smart home products

There are two accessories in particular that make for helpful additions to your Honeywell smart thermostat: the RedLINK Room Sensor and T9 Smart Sensor.

Both room sensors are meant to detect the temperature in individual rooms in the home. Because there can be pockets of air that are warmer or cooler than the rest of the home, the smart sensor works to detect them and mitigate the difference. They also offer occupancy detection to help direct your HVAC system's energy to the rooms that need it. The RedLINK sensor also offers humidity detection.

Honeywell thermostat energy rebates

Depending on your energy provider, there may be smart home energy rebates available. These rebates will cover some or all of the costs of Honeywell smart thermostat. For more information, check with your energy provider to see what, if any, rebates they offer.
