Default Air Conditioning question

I just purchased a 2017 RX350. The one warm day that we had, I turned on the air conditioning and was disappointed with the only coolish air coming out of the vents. I thought the AC needs a charge so I purchased a tank with gauge. I hooked it up and was surprised to see there was a full charge. Is the marginal AC an issue or something that. can be repaired. My next thought is to change the cabin filter and see if that helps.

2017 RX450h with cold air. Definitely check cabin air filter it might be so clogged it is restricting air flow.

In order to test the AC the outside temperature needs to be warm. Are you testing in current Ontario weather (Cold)?

The cabin filter is probably ok. Changing wouldn't hurt anything. Cheap and easy.

Try turning the temp button way up and then way down, if that doesn't work the blending door might be stuck.
