A regular hose is plenty in addition to some coil cleaner and you
really need to take the top off and shoot the water through the coils
from the inside.
(I know a lot of HVAC techs)

+1 Especially the old ICP units that had the old playing card size grill on
them.

Spray the coil cleaner on the coils, let it sit for a minute or two,
then hose it off. Repeat if necessary.

Probably will.

If you know how to check the refrigerant level, you can do the "$100
clean and check".

If ya got the gauges use em, if you know how to interpret the readings.

If that is $29-$39 expect a hard sell for something else and if it is
free, expect them to break something. ;-)


Like a cap? Contactor? Refrigerant top off?
