My air conditioning unit is not blowing very well, some vents feel like nothing others you can feel, but not with the very low power. The air is does not seem to be cool. I have already checked the filters, and I do change them, they were not bad. I also turned off the unit to see if it had frozen up, but it did not seem to change, but in the early morning it seemed to kick on and got cool, but then this moring around 6 am it was just the same as last night. I really hate to have to put alot of money in. I'm moving in 2 weeks.
