The primary function of Emerson thermostats is to save energy, which reviews prove to be true for the Sensi Touch series. Compared to Honeywell variants, Emerson is likely to provide higher efficiency.

Additional Features

Most recommend Emerson thermostats for individuals who want more features on a smart thermostat that are still easy to operate and understand. For advanced programs and customizations, reviews suggest Honeywell as the better option.


Both brands are relevantly easy to navigate, but Emerson's simple design makes it quicker for users to understand its additional functions, while Honeywell thermostats are more effortless to set up.

Value For Money

Honeywell, offering more thermostat choices, is a good deal if you want an affordable unit. Tests show they are efficient, making them an excellent value for money.

While Emerson thermostats are pricier than others, they provide a range of features worth the cost. If you have a few more dollars to spare for a smart thermostat, you might want to add this to your choices.

Honeywell thermostats need a C-wire, so you might have to request additional installation or purchase a separate adapter. However, they are said to have an easier installation.

Maintenance And Repair

Emerson recommends that their users request repair and maintenance from their OEM-certified technicians. They also offer remote assistance but suggest using original parts for replacement.

Honeywell thermostats can be maintained and repaired even without the help of their team as long as you follow the right processes. Although, they have a support program open for further assistance.


If you prefer a simple design with just enough features to make it customizable and don't mind the price tag too much, Emerson thermostats might be the one for you.

But if you're on a tight budget and prefer flexible control or more function options, you may want to check out Honeywell thermostats!

How Do I Find A Good Thermostat?

Usually, the best thermostat for your home varies on its current condition and your personal preference. You can choose several types, each offering benefits that might be just what you need!

To sum it up, here's a guide on the things you should keep in mind when shopping for a thermostat:

1. Weigh The Options

Thermostats can come with simple or complex systems, which often determines their price ranges. A programmable thermostat is likely to have fewer features but is easy to use and affordable, while smart thermostats give you control and can adjust to your habits at a higher cost.

Narrow down your options by checking what each thermostat offers and picking out the best fit for your needs (features, size, user-friendliness, etc.) and budget!

2. Consider Your HVAC System's Needs

One of the main factors that affect your choice is your heating and cooling system.

Although most thermostats work on typical HVAC systems, some models may have specific exceptions, especially with smart variants. If your heating and cooling systems are separate, you might need a thermostat for each of them and their zones.

If you need more thermostats, consider cheaper options to cater to each location and system in your home. But a smart model is a convenient and good long-term choice if you only need one or two and have a large budget.

3. Evaluate Existing Wiring

Next to your HVAC system, you will also need to check your current wiring, especially if you already have an existing thermostat. That way, you can identify the adjustments you need to make before installing different units.

For programmable thermostats, they can work with at least two low-voltage wires, making them compatible with older heating and cooling systems. On the other hand, newer models, such as smart thermostats, require C-wire to provide power for displays and Wi-Fi features.

You can also contact an HVAC technician to evaluate the wiring for you if you aren't sure about what wiring you have.

4. Choose What Fits Your Interior

Some homeowners value the importance of aesthetic impact, so they pick a thermostat that fits well with their existing interior. Fortunately, most thermostats now come in different styles and sizes, giving you various designs to choose from.

Note that this isn't always necessary, but having a nice-looking thermostat is undoubtedly a plus!

Does It Matter What Thermostat I Buy?

Yes, the kind of thermostat you buy matters if you want to ensure you're getting a good deal out of your money. One of the top reasons to get a thermostat for your HVAC system is to maximize cost and energy efficiency, so evaluating your options is essential.

With the right thermostat, you'll be able to save on years worth of extra heating and cooling costs. At the same time, it will keep temperatures within your home constant and comfortable even during the most drastic seasons!

Listed below are the basic types of thermostats available:

Non-Programmable Thermostat

Non-programmable or manual thermostats are ideal if you spend more time at home. They offer the most straightforward operation but require you to adjust the settings manually whenever you want to change the temperature.

Some non-programmable thermostat models communicate with your HVAC system to keep the temperature within your preference, achieving higher energy efficiency for a small expense.

Programmable Thermostat

You can set a programmable thermostat to adjust temperatures automatically by schedule, including day or night, daily, and weekly. They are favorable for homes in locations with frequent fluctuating temperatures.

Wi-Fi Thermostat

As the name suggests, Wi-Fi thermostats are programmable thermostats that function when connected to wireless networks and can be operated through them, meaning you can control the settings remotely.

Smart Thermostat

The most modern thermostat available so far are smart thermostats, which operate using automated tools and advanced technology. The distinct feature of a smart thermostat is the ability to learn your habits and adjust temperatures from there.

These functions and features make them the most expensive option but can surely help you save on heating and cooling costs for a few years.

When Should I Replace My Thermostat?

If you already own a thermostat but are considering replacing it, you should consider a few things. A thermostat usually lasts a few years or longer with the proper maintenance, but here are a couple of factors that may urge you to have it changed:

Wear And Tear

Replacing HVAC Units

When installing a new HVAC unit, you may want to replace your thermostat with a model that handles the system better. Depending on which works best with your new heating and cooling system, you can choose between low-voltage, line-voltage, and millivolt thermostats.

Mismatched HVAC System And Thermostat

Not all thermostats respond to all HVAC systems, commonly when using a newer thermostat with an older HVAC unit. In this case, look into the setup's wiring to find which thermostat is compatible with your system.

Thermostat Upgrade

It's OK to replace your thermostat if you want to upgrade your current system. A thermostat that functions better with your system will likely offer you more savings and convenience!
