A/C not cooling.

Turned on my central air unit but not cooling the house. The fan outside is running and the filter inside is clean just replaced. I did notice that air coming from the unit outside is not hot so o don't think it's sucking out the heat from inside . any advice will be great .

The fan running outside would indicate it’s getting a call to run. Make sure the compressor is actually running.

See if the contactor is pulled in, and the compressor is pulling amps.
You should be able to hear the compressor running as well

First off, feel the suction and liquid lines. Is the suction line cold? Is the liquid line warm?
The contactor will be in the electrical cabinet in the condenser. There will be live exposed high voltage in that panel.

You should have a meter and be ok around high voltage. May be a capacitor.

It is not easy to fix a 'not cool' problem. It can be caused by many different issues. so you may have to call an AC tech to help you.
