Again basic good video but a couple of added comments.
The foam insulation covers look very tatty in your specimen., There are new covers available from MB to do a really nice presentational job for not much money .
The other is get a can of foaming coil cleaner from Home Depot if you want cheap, otherwise BG Frigi Fresh if you want that like new car A/C-Heater smell.
If on the other hand if you want to impress the cab interior with a hospital like smell or English Country Garden then Zep's Zepanamatic , big can & good for cleaning the dash as well is nice.
Spray it on exposed evaporator coil section once you have the filter removed .
As it foams up it will not only clean the coils/matrix improving A/C performance but leave the cabin smelling very fresh when you turn on the blower fan.
As with a lot of thing fixing cars for profit or DIY satisfaction, presentation is everything.
I/We have a selection of these according to car & customer.
High end Lux car, BG Frigi fresh +$$$
Like new Sprinter, Zep $+1
For TIN vans and for those that don't like emptying your chem toilet then its a Home Depot & Zep Combo. Cheap' n Cheerful.
Good video again.
