I had a really bad dream last night. I woke up and felt extremely hot due to the anxiety, I wanted my thermostat to do the cooling more than it usually does but it was already set to the maximum temperature. This had me thinking that why my nest thermostat is not cooling
However, that day passed but again I faced the same inconvenience and that too at night. Now my question changed to “Why is nest not cooling at night?” It is not like I haven’t dealt with any issue before. I have solved issues like when nest thermostat’s battery won’t charge up or the time when I wanted Nest to hold the temperature. But this was an unusual issue for me.

NEST AIR CONDITIONER NOT COOLING – TRY THESE FIXES!
Following fixes will help you in solving the problem very easily. Just make sure that you follow each and every step very carefully.
1. RESETTING THE SCHEDULE:
These self-learning thermostats learn your temperature patterns and then set a schedule accordingly. However, there is a possibility that your thermostat has set the temperature incorrectly so it is better to perform a reset as soon as possible.
STEPS TO FOLLOW:
STEP 1 – Navigate towards the “Settings” of your thermostat
STEP 2 – Go to the “Reset” option and select “Schedule”
STEP 3 – Now press “Reset” or “Clear” depending upon the model of your nest thermostat
This will clear your old schedule and you will be able to set a new one.
2. RESTARTING THE HVAC SYSTEM:
Sometimes an usual bug could cause an error in your HVAC system so it is better to perform the turn off – turn on trick. For this you will have to turn off your HVAC system for some time and then turn it on again in order to ensure its proper working.
STEPS TO FOLLOW:
To restart your HVAC system, follow the following steps.
STEP 1 – Turn OFF the HVAC system from your breaker box
STEP 2 – Repeat the same process for the thermostat as well
STEP 3 – Wait for some time and then turn it back ON
After doing this, adjust the thermostat accordingly and see if the problem is still there or not.
3. WIRING CHECK:
Sometimes the incorrect placement of wires causes issues like this. It is important to have a check and balance on the wiring part because without it your thermostat might show abnormal behavior. Either the wires are loosen up or shortened. Another reason could be that the C-wire isn’t installed. C-wire is important because it powers up the nest. For this you will have to inspect the wires carefully and see which wire is the troubling one. If the common wire is missing then make sure to identify it and install it.
4. AC REPAIRING:
If your AC is damaged or not working properly then it could be the main reason for why your thermostat is not cooling at night. Your thermostat’s AC needs more maintenance than anything else. You will have to buy new AC filters every month and along with this you need to keep the air filters clean so that any unnecessary stuff couldn’t block the cool air. Make sure you get them cleaned on and off and also buy new stuff whenever required.
5. CHECKING DRAIN LINES:
Due to excessive use the drain lines and panes could get clogged up with water and dirt. You need to flush away this stuff as soon as possible. So make sure you keep the drainage system clean by following the below steps.
STEPS TO FOLLOW:
STEP 1 – Remove the cap from your drain pipe
STEP 2 – Take a thin wire brush and brush the drain pipe
STEP 3 – Prepare a mixture of bleach and water (having equal amounts) and pour it in
STEP 4 – Wait for the mixture to sit and then turn ON the AC
6. BATTERY REPLACEMENT:
Sometime old batteries prevent your thermostat to do the sufficient cooling. If this is the issue then the easiest fix is to replace the old batteries with new ones. Make sure you bring high-quality batteries because cheap quality batteries cause more damage to your system.
7. ENERGY-SAVING BOX REMOVAL:
Energy-saving box, as the name suggests is a box which is placed to save the energy. This box will reduce the power supply as soon as it detects high-power consumption. Also the electricity is cheaper at night so this box could be preventing your thermostat to not do the cooling at night. Ask the related technicians to remove this box as soon as possible.
