Put in 4 years ago by ace air. This is the second time I've been without a/c the second time I've had to wait the day of no air till the second day. We also purchased 3 new registers, we got 3 vents so all the air goes into the room with the not able to adjust vent. We had to block a portion of the vent with foil so the other rooms get a/c. Now the new intake and filter. Cheapest built. already wont stay shut and hold the filter in. This sucks being's I paid thousands for this work to be done...use them at your own risk. When called this in to them, they wont do anything to correct the registers. Also they are very happy to charge me to fix this 4 year old boat anchor. to bad so sad they have been paid.
