How To Fix It

Why Ecobee Thermostat Not Holding Temperature?

Ecobee thermostats are handy devices that allow you to control your home’s temperature anywhere. As long as they’re connected to WiFi, you can control them from your smartphone or other smart devices, like Alexa. But you may have noticed that your Ecobee thermostat isn’t holding its temperature, which is something you need to fix.

Your Ecobee thermostat may not be holding its temperature for several reasons. For example, it won’t maintain its temperature if you don’t set it up correctly or if you need to update your device’s hold settings. However, there could also be an issue with your HVAC system.

This article will discuss the main reasons an Ecobee thermostat doesn’t hold its temperature and the solutions. So, keep reading if you want to learn more!

1. You Didn’t Set Up Your Ecobee Thermostat Correctly

First and foremost, you must ensure you’ve set your Ecobee thermostat up correctly. Once the device is installed in your home, it’s relatively easy to set it up the way you want. There are different things that you can set up on your Ecobee, including:

  • The schedule
  • Smart recovery

Both of the above can impact your Ecobee’s temperature hold. 

Firstly, let’s talk about the schedule option. You can set a schedule for your Ecobee thermostat, so it’s constantly at your desired temperatures. For example, you may work from home on Mondays and prefer to have the heat set to 70 degrees F (21.1 degrees C). But for the rest of the week, you might work in the office and want to keep the home at 62 degrees F (16.67 degrees C) to save on energy costs. 

In that case, you could set a schedule so that your home is always 70 degrees F (21.1 degrees C) on Mondays. You could also set it to 62 degrees F (16.67 degrees C) for the rest of the week. If you haven’t set your schedule correctly, your temperature won’t hold as you want it to. 

Now, let’s talk about the smart recovery option. The smart recovery setting allows the thermostat to predict the most appropriate settings for your home, but it can take some time to work correctly. So if your thermostat is new, it might not set to the proper temperatures for a while, and it likely won’t hold the right temperature.

The Solution

If the issue is that you haven’t set up a schedule properly, you can set up a schedule correctly by going to the Ecobee website and logging into your account. From there, you can add preferences depending on the day and time. 

Also, you and no one else should interfere with the temperature when there’s a schedule set because it will mess with your temperature settings.

If your issue is caused by smart recovery, the best option is to turn it off entirely until your thermostat has had enough time to get used to the surroundings.

2. Your Ecobee Thermostat Needs To Be Reset

If you know that your settings are all correct, your Ecobee might just need to be reset. A reset will remove all your preferences and settings, so you can start over again. This will also help if you have a lot of different settings and aren’t sure which ones are causing issues.

You can do different resets, but the best one in this instance is the reset schedule and preferences option.

The Solution

Here is a brief and easy guide on how to reset your Ecobee thermostat:

  1. Go to your Ecobee device.
  2. On the main menu, navigate to the settings tab.
  3. From there, you can choose the reset option of your choice.

You can also do a full factory reset if you wish, but beware that this will wipe the device, and you’ll need to start everything from scratch.

3. Your Ecobee Thermostat Needs an Update

Thankfully, Ecobee thermostats receive updates automatically once they’re connected to the internet, so it’s unlikely that this is your issue. However, if your Ecobee isn’t connected to the internet and misses an update, this could be why it isn’t holding its temperature. 

Therefore, it’s good to make sure it has a secure internet connection. Plus, it won’t have many other functions when it’s not connected to the internet.

The Solution

Ensure your Ecobee thermostat is up to date by ensuring it remains connected to the internet at all times. There’s no need to manually update your Ecobee because it will do so automatically over WiFi. If you realize your Ecobee was disconnected from the internet, it should update once you reconnect it.

You might be wondering how you can check the internet connection on your Ecobee, and luckily it’s easy. All you need to do is go to your Ecobee device and navigate to the About tab (which you can find on the main menu). From there, you can check the internet connection.

4. You Need To Update Your Hold Settings

A hold occurs when you manually choose the temperature on your Ecobee thermostat. The amount of time a hold lasts will depend on your settings. For example, some holds may last for a few hours, while others may last until you make a change.

So if you have a schedule and then change the temperature manually (thereby interfering with the schedule), your device will be in a hold temperature. If you do this but notice the temperature doesn’t hold for more than an hour, it means you need to change your hold settings so that they last longer.

The Solution

If your hold setting doesn’t last as long as you’d like, you’ll need to change the settings. To change the hold settings, follow these steps:

  1. Go to your Ecobee thermostat.
  2. Navigate to the preferences settings tab.
  3. From there, you can find the hold settings.
  4. Change the hold settings to your preferences.

Once you change the hold settings, the temperature should hold for as long as you want.

5. There’s an Issue With Your HVAC System

If you’ve gone through this article and aren’t sure why your Ecobee thermostat won’t hold its temperature, there may be an issue with your HVAC system rather than the thermostat itself. There are several things that could be broken, including:

  • The air filter. The air filter is important because it removes small particles (like dust) from the air. If the air filter is damaged, your HVAC unit could experience issues.
  • The blower. The blower essentially blows warm or cold air into the atmosphere of your house. The blower must be working if you want the HVAC to work correctly.
  • The coils. HVACs have different coils, and all of them must work correctly. An example is the evaporator coil, which absorbs heat.
  • The heat exchanger. This component transfers thermal energy, so it’s another essential part of the HVAC system. If it’s not working correctly, you may experience issues with your Ecobee. 

If a component of your air conditioning unit is broken, you might notice that the temperature doesn’t hold when you want it to be colder. On the other hand, you might notice warm temperatures don’t hold if a component on your heater is broken.

The Solution

To fix this problem, you should hire a professional to look at your HVAC unit. If you know how to, you could inspect it yourself. However, it’s not worth it if you don’t know what you’re doing because you might worsen the problem.

If you want to check it yourself, check for things like broken or damaged wires and the fuse box.

There are different reasons why your Ecobee thermostat might not hold its temperature. Here are some of them:

  • You haven’t chosen the correct settings
  • You need to reset the Ecobee
  • The Ecobee needs an update because it’s disconnected from the internet
  • You need to change the hold settings
  • A component of your HVAC system is broken

Thankfully, each issue has a resolution, which I have discussed in this article. You should call an HVAC professional if no other solution has worked.
