Ecobee calibrating heat cool disabled message has appeared? Don’t lose more time looking for a solution and keep reading.

By the end of this guide, we will surely have your Ecobee fixed as well as the issue explained in detail.

If your Ecobee is calibrating, the device is currently getting a reading of your home’s temperature. To fix the issue, simply wait for 5-20 minutes depending on your Ecobee’s performance and make sure your HVAC system is not cutting the power to the thermostat.

Before we proceed with the guide, make sure to wait 5-20 minutes.

Ecobee will calibrate every once in a while to get a proper reading of your household’s temperature and you should let it finish the check.

Why Is Ecobee Calibrating Heat/Cool Disabled?

As we’ve mentioned above, the calibrating of your thermostat is nothing to be afraid of.

It will usually run a check of your household’s temperature, which should not last longer than 20 minutes. Yes, it will disable your household’s heat and cooling, but only temporarily.

If the check persists for a while now and your Ecobee seems to be unresponsive, here are some reasons why that could be happening:

1. HVAC Power Issues

If the HVAC keeps cutting off your thermostat’s power supply, it won’t be able to finish the calibration process.

2. Sensors Problem

As you know, sensors of your thermostat would scan the temperature surrounding the device, but if there is an issue with them, your thermostat might be unable to get the reading.

3. Outdated Firmware

Ecobee initiates a calibration whenever it reboots. It could be happening due to outdated firmware.

4. Furnace Overheating

Quite rarely, but not excluded is the fact that your furnace is overheating, impacting your thermostat’s reading.

5. Condition Obstructions

If water has built up in your conditioner, it could be making your thermostat calibrate for longer than usual.

Having that said, let’s learn how to resolve the issue of your thermostat in a matter of minutes.

How To Fix Ecobee Calibrating Heat And Cool Disabled Issue?

Even though calibrating is the initial part of the process of your thermostat scanning the temperature, it could get really frustrating at some point waiting for your thermostat for hours to calibrate.

Luckily for you, we’ve extracted the best troubleshooting information you could come across and put it in the solutions down below.

Solution #1 Configure The Calibration

It is possible that the configuration of the calibration itself is not set up correctly.

Follow the steps down below to set up your Ecobee’s calibration the correct way:

  1. Go to the Menu of your thermostat.
  2. Tap the “Installation Settings” tab, located in the settings menu.
  3. Now locate the “Thresholds” tab and select “Temperature Correction”.
  4. Adjust the temperature to the correct one for your configuration.

Play around with the Temperature Correction feature’s temperature and see what fits in with your thermostat.

Solution #2 Reconnect The Power Cord

Now that you’ve configured the calibration of your thermostat, another quick solution to the issue is to reconnect the power cord.

This method is often referred to as a hard reset or power cycle because it will actively discharge your device.

Here is how to reconnect your Ecobee’s power cord:

  1. Locate the 24V C wire, which should be in red color, going in from the side of your thermostat.
  2. Disconnect the wire and wait for 5 minutes.
  3. Reconnect the C wire and test your thermostat.

Keep in mind that once you reconnect the wire and turn on the thermostat, another calibration will initiate.

If it keeps going on longer than 20 minutes, proceed with the next solution.

Solution #3 Clean The A/C’s Drain Pan

As we’ve mentioned above, if your A/C’s drain pan is full of debris, it could be affecting your thermostat’s ability to scan the surrounding temperature, thus the calibration process will persist longer than usual.

This is why our next recommendation is to make sure your A/C’s drain pan is clean.

Since there isn’t much we can do, due to your specific A/C and drain pan configuration, it is up to you to clear your system firmly.

Make sure to clean all of your A/C’s drain pans (if you have multiple ones) and test out the calibration afterward.

Solution #4 Update Your Ecobee

As you know, outdated firmware could always cause issues with your device’s OS.

You must make sure that your Ecobee is up-to-date, before applying any of the remaining solutions.

Ecobee would usually auto-update, but system issues might have prevented the notification from alerting you.

You must make sure that the thermostat is connected to Wi-Fi and as soon as the update is available, it will automatically apply it to itself.

Keep in mind that the internet connection must be reliable for the thermostat to start downloading. If there are outages, any updates might have been skipped and your software could be outdated.

Solution #5 Clean The Air Filter

Users report that your thermostat’s ability to scan the surrounding temperature will be obstructed if the air filter is filthy.

This is why we recommend running an overall check of the air filter and cleaning it of any dust and debris.

Here is how to clean your air filter:

  1. Go to the clogging hole of your air filter and take it out.
  2. Use a vacuum cleaner to get rid of the dust within the air filter.
  3. Manually remove any larger pieces of remains from the air filter’s fences.
  4. Install the air filter and screw it tightly.

Once done, reboot your thermostat and check if the calibration process has finished now and it will start heating/cooling.

Solution #6 Factory Reset Your Thermostat

If nothing worked so far and Ecobee calibrating heat cool disabled after all of these solutions, then you should bet on a factory reset to resolve the issue for you.

If the problem has something to do with the software of the device, you should definitely reset your thermostat and reset ALL of its features.

Here is how to reset your Ecobee thermostat:

  1. Go to the menu of your thermostat.
  2. Hit the settings.
  3. Scroll down until you find “Reset”.
  4. Choose “Reset all settings”.
  5. Choose a reset option. (We recommend going with an overall reset)
  6. Wait for your thermostat to finish.

Keep in mind that the calibration may not come up once your thermostat finishes resetting.

Perhaps from the second boot, your thermostat will start working as usual and fix the calibration issues.

Bottom Line:

To fix calibrating heating/cooling issues with your Ecobee thermostat, reconnect its power adapter, clean the air filter and the A/C’s drains. Next, check its internet connection and perform a factory reset.

Now that you know why Ecobee calibrating heat cool disabled, we hope you’ve managed to fix your thermostat’s calibration issues.

After all, your thermostat could have come to an end life and this is the first sign you should get a replacement as soon as possible!
