I have a central A/C unit that needs cleaning (not the duct work). Can
this be done by a homeowner or is this really a job for a pro A/C

service and in the end I end up doing things myself.
I have a 3 ton American Standard.


You can do considerable damage if you are not careful & don't know what
can happen
First, always cut all power off to the unit.

Never use detergents on coils & fins as there are oils etc., that will
leave an insulating film on them.
We use special coil cleaners, and some of those are powerful & dangerous
to use.

Keep the water stream straight with the fins or it might bend them.

My advice: Call a HVAC contractor to service the entire system. - udarrell
