I did this the other day and it made a HUGE difference!

Clean Out Your HVAC Box

 

thats good info

 

great post, will be trying my hand at that very soon.

 

Hey guys, i'm confused,
what exactly did it do, make the a/c colder or something

 

I pulled all of my vents out, turned the blower on high and smacked the bottom of the box, got about 20-30 palmetto leaves out of it (florida truck) those things make some noise when they get stuck in the ducting......

 

what about cleaning the drip pan side out? the elbow backed up some junk in it and water will run out of the door that opens when you turn it on max ac. i'm sure cleaning the evap off will help but i need to get the junk out the engine compartment side to get the water out.

 

mines already done from when i did my heater core about 2 months ago but stil a great write up!
