New Heating / Cooling install.

I just had a new furnace/coil/condenser installed and had a question. I had a number of different estimates given so I felt good about the sizing. Now, with the system in for less than a week I have a question.

I have some shrink wrap up on some windows in the house still and when the furnace starts to blow the pressure in the house changes quickly and the shrink wrap pulls out towards the exterior. When it stops blowing it lets up again just as quickly.

What is this telling me about the pressure in the house and how the HVAC system is acting to have this effect. I don't even to really know how to ask this correctly.

Thanks in advance for any help.
