My a/c vent where my filter is sucks so much air that my ears hurt.Could it be too much pressure?

Is the vent whistling or the pressure difference when it comes on makes your ears hurt? How long hasit been going on?

Sounds like maybe not enough or return is to small,, has it always been this way?is it a new system?

Its been going on for 3 weeks(since they change the a/c unit.when I change my filter,the suction is so powerful that my hair are sticking up!I called the a/c comp. who came to replace the unit and they said it was normal to have that much pressure...

It is a new system.. and that when my ears start hurting.. but could that be that powerful?I mean, my hair are sticking up when I change my filter!

Your hair shouldn't stand on end by any means... Are you shocking yourself, meaning static electricity, a lot when touching other people or things in your home?
