wanted to see a videoHow do i change air-con filter at home?
I don't know where a video would be, but if this is central air try this. On the unit inside the house there should be 2 panels on the front of it. They will usually be lift and pull out to remove them. The bottom one is where the filter usually is, but you normally need the top one out to get the bottom out. You should see the filter when you remove the bottom panel. They are usually a size like 16X25X1. The filter should show it's size on the side. Go to your hardware store, or a Lowes or home depot. You can get a replacement filter there. They have the ones that are like a blue fiberglass filter, I don't recommend those. I usually get the 3M Brand filters. They have a filter efficiency number on the filter. The higher the number, the better the filter. I use 1250 or 1700. You should just be able to slide the old one out, and the new one in. Replace the bottom panel and then the top panel, and make sure the system turns on. There is a switch you will see that one of the panels, usually the bottom, presses against. If the system doesn't turn on check to make sure both panels are on all the way.
