Why am I not getting air through my vents?

How much airflow should be coming out of my vents?
How Strong Should Air Come Out Of Vents? The answer to this really depends on your system. But as a rule, the airflow from your vents should be roughly equal throughout the whole system.

Why is my central air not working?
If your AC indoor fan isn’t working, first check to make sure a breaker hasn’t been tripped. If all is OK, check your air filter. If it’s blocked, then you may be able to fix it yourself.
