On a hot day it can be extremely frustrating when your Ecobee is struggling to blow cold air into your home. This is especially true when your house is sizzling hot and even with your windows open it is still warm!
You might even start to wonder, “Why is my Ecobee is not blowing cold air?” We reveal the 9 main reasons why!
An Ecobee might not blow cold air if the temperature is not set to overcool, the thermostat might be in heating mode, the temperature is set too high, the thermostat is not connected to HVAC, the blow motor failed, the air/lint filter has faded, the thermostat is not in cooling mode, the temperature is set too high or the barometric pressure has changed.
You may think you’re getting an honest answer from the experts at Ecobee when they tell you to schedule a service call. But rest assured, there are many reasons why your ecobee not blowing cold air, and making a service call might not be entirely necessary.

9 Main Reasons Why Your Ecobee is Not Blowing Cold Air
1) The Temperature Is Not Set to Overcool
If the temperature is not set to overcool, you will feel warm air even if your blower is running. To solve this problem, adjust the temperature setting to match the current temperature by using your ecobee3, Ecobee3 lite, or Smart-si thermostat’s touchscreen display.
2) The Thermostat Might Be In Heating Mode
Make sure that your ecobee thermostat is not in Heating Mode and that you have it turned on for cooling rather than heating. While your ecobee thermostat can be programmed for both heating and cooling cycles per day, it will only blow cold air when the unit is in cooling mode.
3) The Temperature Is Set Too High
A common issue is that the temperature is set too high, and the ecobee thermostat is not cold enough. Turn your thermostat down before scheduling a service call so you can save money on cooling bills and ensure that you are comfortable by turning off your heat during the cooling season.
4) The Thermostat Is Not Connected To HVAC
Make sure that your thermostat is connected to the HVAC system. If you’re still not getting cold air when the blower kicks on, this issue may be your valve being stuck open.
5) Blower Motor Failed
The blower motor is responsible for driving air through the ventilation system. A blower motor failure can cause the system to underperform and not provide the proper airflow levels necessary for adequate heating or cooling comfort levels.
Part D44-16 of the National Electrical Code states that a replacement blower motor for a single-stage furnace should be installed by an electrically qualified person.
6) The Air/Lint Filter Has Faded
The lint filter, also known as an air filter, is located anywhere on and around the furnace and blower. It is used to trap and keep small debris from entering the ventilation system. When not properly cleaned on a regular basis, it will begin to fade and result in faster wear on all of your home’s components.
A solution is to vacuum the furnace and/or blower chamber every month or so with a vacuum cleaner that doesn’t create excessively.
7) The Thermostat Is Not In Cooling Mode
Make sure that your ecobee thermostat is in Cooling mode and that you have it turned on for cooling rather than heating. While your ecobee thermostat can be programmed to run both heating and cooling cycles per day, it will only blow air when the unit is in cool mode.
8) The Temperature Is Set Too High
If you have it set too high, then the temperature won’t register correctly on the screen. Your thermostat may show a higher temperature than what is actually inside your home, which will cause many calls for service because you feel like your system isn’t working properly.
This can also waste energy because you may get hot when there are no actual reasons for being hot, or you may turn up your thermostat to a higher degree than what is necessary and end up paying more on your energy bill.
9) Barometric Pressure Has Changed
The barometric pressure in your home determines how much pressure there is inside compared to the outside air pressure. An increase in barometric pressure can result in the heating system working harder and running longer than usual.
As a result, you will have to run your system longer and contributing to higher heating bills. A solution is to turn on the AC before leaving for work or overnight since that is when the most energy is being used for cooling operations.
Why is My Ecobee Not Blowing Cold Air? Conclusion
You are always a step away from addressing a cooling system problem, and with most cooling systems, you should be able to fix the problem within three minutes. Understanding the common causes will help you to spend less time troubleshooting and more time enjoying your home! Stay cool!
