Why is no air coming out of my AC vents?
If you may have mistakenly set your system to a higher temperature, your system won’t know to begin cooling the space. Make sure all windows and doors to the outside are closed. Even just one or two open windows can bring in enough heat to result in your AC struggling to cool your indoor space. Clean or replace the filter, if needed.
What does it mean when your AC is running but not Cooling Your House?
Your thermostat is switched to ON. If your thermostat switch is set to ON, that means the blower will run constantly—even when your system isn’t cooling your home, which will result in warm air blowing from your vents. How to fix it: Switch your thermostat to AUTO (see image below), so air only blows from your vents when the AC is cooling.
Why is my air conditioner not blowing cold air?
Check exhaust hose for kinks or blockage: If hot air can’t get out of the vent, the air conditioner won’t be able to cool off your room air. If your AC is blowing cold air out of the top vent, but your room still isn’t getting cold, your room is probably too hot or too large for the heat capacity of your air conditioner.
Where does the coldest air come from on an AC unit?
The rooms closest to the unit will receive the strongest and coldest air flow, while those farthest away will unfortunately get the weakest air flow. One way to balance out the air flow to all the rooms in your house is to close the vents in the cooler rooms partway.

Why does my air conditioner keep blowing cold air?
Make sure the fan setting is set to “auto” not “on”, which will cause your AC to blow air even if it’s not being cooled. 2) Check your air filter — If the air coming out of the supply vents is weak and not very cool, check to see if the air filter is dirty and change it if necessary.
