To address the issue of a Honeywell air conditioner not cooling, the primary culprit often lies in a dirty air filter that necessitates replacement. A clean air filter ensures optimal airflow, which is crucial for efficient cooling. Additionally, other potential problems may include a clogged condensate drain, which can impede proper drainage and affect performance. Low refrigerant levels are another common concern, as they prevent the system from cooling effectively. Lastly, a faulty evaporator coil can also disrupt the cooling process, requiring professional inspection and possible repair. Regular maintenance can help mitigate these issues and keep your air conditioning system running smoothly.
Why is my Honeywell not blowing cold air?
- The first reason could be that the filter is dirty and needs to be replaced.
- The second reason could be that the coils are frozen and need to be thawed out.
- The third reason could be that the compressor is not working properly.
Why is my Honeywell thermostat on cool but not working?
If your Honeywell thermostat is on cool but not working, there are a few things you can check to troubleshoot the issue. First, make sure that the thermostat is set to the correct mode for cooling (usually marked with a snowflake icon). Next, check that the temperature is set lower than the current room temperature.
If both of these settings are correct and your thermostat still isn’t working, it’s possible that the batteries are low and need to be replaced. Finally, if your thermostat is still not working, you may need to call a professional for help.
Why is my air conditioner running but not cooling the house?
One of the most common questions we get from homeowners is, “Why is my air conditioner running but not cooling the house?” While there could be a number of reasons for this, the most common cause is that the air conditioner is low on refrigerant. When an air conditioner is operating, it pumps refrigerant through its system.
This refrigerant is what actually cools the air inside your home. So, if your air conditioner is low on refrigerant, it can’t cool the air properly. There are a few other potential causes of this problem, such as a clogged air filter or a problem with the air conditioner’s evaporator coil.
But the most common cause is simply that the air conditioner is low on refrigerant. If you think your air conditioner might be low on refrigerant, the best thing to do is call a qualified HVAC technician for service. They will be able to diagnose the problem and, if necessary, add more refrigerant to your system.
Why is my AC not working Honeywell?
If your AC isn’t working, there could be a few different reasons. Check to make sure that your thermostat is set to “cool” and that the temperature is set lower than the current room temperature. Also, check to see if the fan is set to “auto” or “on.”
If it’s set to “on,” the fan will run continuously, even when the compressor isn’t running. If the fan is set to “auto,” it will only run when the compressor is running. Next, check the outdoor unit to make sure that the condenser coils are clean, and the fan is running.
If the coils are dirty, they won’t be able to transfer heat properly. If the fan isn’t running, the coils will eventually overheat and the compressor will shut off. The problem is likely with the indoor unit if everything looks good outside.
Start by checking the air filter. A dirty filter can restrict air flow, causing the evaporator coils to freeze. If the filter is dirty, replace it and see if that fixes the problem.
If the filter is clean, the next step is to check the evaporator coils. Airflow is restricted if they’re covered in frost or ice. Turn off the AC and let the coils thaw.
Once they’re thawed, clean the coils and make sure that there’s nothing blocking the air flow.

How to set Honeywell thermostat to cool
If you want to cool your home with a Honeywell thermostat, there are a few things you need to do. First, you’ll need to set the thermostat to the “cool” setting. Then, you’ll need to adjust the temperature to your desired setting.
Finally, you’ll need to make sure that the fan is set to “auto” By following these simple steps, you can keep your home cool and comfortable all summer long!
Thermostat says cool on but no air
First, check to see if your fan is set to “auto” or “on.” If it’s set to “auto,” the fan will only come on when the system is cooling. If the fan is set to “on,” it should be running constantly.
Next, check your air filter. A dirty air filter can restrict air flow, causing your system to work harder (and use more energy) to cool your home.
Replacing a dirty air filter with a clean one can often fix the problem. If your air filter is clean and your fan is set to “on,” the most likely culprit is a problem with your air conditioner’s compressor.
The compressor is responsible for circulating refrigerant through your AC system. If it’s not working properly, your AC system can’t do its job.
Sometime trying to fix the problem yourself could make it worse, so it’s best to leave it to the pros.
Honeywell thermostat set to cool but heating
If you have a Honeywell Thermostat and it is set to cool, but the heating is coming on, there are a few possible explanations. First, check to make sure that the system switch is in the correct position. The system switch should be set to “heat” if you want the heating to come on.
If the system switch is in the correct position, the next step is to check the set point. The set point is the temperature that you have set the thermostat to. If the set point is set too high, the heating will come on.
Finally, check to see if the fan switch is in the “auto” position. If the fan switch is in the “on” position, the fan will run continuously and the heating will come on.
Honeywell rth6360 not cooling
If your Honeywell RTH6360 isn’t cooling, there are a few things you can try to fix the problem. First, check to make sure that the thermostat is set to the “cool” setting.
Next, check to see if the filter needs to be replaced. If the filter is dirty, it can prevent the unit from cooling properly.
Finally, check to see if the coils are dirty. If the coils are dirty, they won’t be able to absorb heat properly, and the unit won’t be able to cool effectively.
Honeywell thermostat fan on not working
If your Honeywell thermostat’s fan isn’t working, there are a few possible causes. First, make sure that the thermostat is set to “Fan On.” If it is, then check to see if the batteries need to be replaced.
If the batteries are fine, then the problem may be with the thermostat itself and you may need to call a professional for help.
Honeywell thermostat not working
If your Honeywell thermostat isn’t working, there are a few things you can check to try to troubleshoot the issue. First, make sure that the thermostat is set to the correct mode for heating or cooling. Next, check the batteries and replace them if necessary.
Finally, check to see if the thermostat is set to the correct temperature. If none of these things solve the problem, you may need to call a professional to help you troubleshoot the issue.
Honeywell thermostat stuck in delay mode
If your Honeywell thermostat is stuck in delay mode, there are a few things you can do to try to fix the issue. First, check to make sure that the batteries are fresh and that the thermostat is properly plugged into the wall outlet. If the problem persists, you may need to reset the thermostat by pressing the “RESET” button on the back of the unit.
If the thermostat is still not working properly, you may need to replace it with a new one.
Honeywell pro series cool on blinking
If your Honeywell Pro series cool is blinking, it may be an indication that the system is not working properly. Here are some things to check:
- Make sure the power is on.
- Check the circuit breaker or fuse box to ensure that the power to the unit is not interrupted.
- Check the batteries. If the batteries are low, they may need to be replaced.
- Check the filters. If the filters are dirty, they may need to be replaced.
- Check the thermostat. If the thermostat is set incorrectly, it may need to be adjusted.
- Check for leaks. If there are any leaks in the system, they will need to be repaired.
Next Steps
If your AC isn’t cooling, there could be a variety of reasons why. It could be that your AC unit is too old and needs to be replaced, you may have a clogged filter, or your AC unit may be low on refrigerant. If you’re not sure what the problem is, it’s best to call a professional to come take a look.
