Indoor Coil Cleaning on Carrier Furnace/AC

jim97gst

I have a Carrier Furnace/AC unit. I recently had the board replaced because the furnace wouldn't come on. The technician said that it needed "indoor coil cleaning". He wanted $350 to do it, but said we could do it ourselves but it would be a lot of work. He said to buy a special brush, use simple green, and be very careful to not bend the fins. I don't know for certain what I need to take apart to get to the indoor coils. Picture attached for reference. Any help would be greatly appreciated.

Need to delete that icon of a picture you posted, and put in post a real picture.

You should seriously consider paying a tech to clean this for you.
You can damage you furnace or evaporator coil attemting this...

Remove the 5/16"screws


Expose the coil



The top is shown removed here but you need to remove the triangular front panel to clean it.



I prefer the pumpdown and removal for cleaning outside method. It will cost more but end up much cleaner.
