This product should not harm the vegetation surrounding your unit unless you purposely spray it on directly. Also depending on what sort of vegetation is around the unit it could be interfering with air circulation to the condenser further reducing its inefficiency.
As it was used, I don’t need the window units to come out. Hope it will help
It hasn't ruined any plants around my system. Just don't overdue it with spraying.
You have a lot of I can't, this sounds like a service call I would get many years ago. The homeowner would show me the unit and say fix it and don't leave a mess. Sounds like you have yourself between a rock and a hard spot. You need to get the front cover off so that you can spray the cleaner on the evap. coil, the best suggestion is to get a spray bottle fill with warm water and spray the coil as best you can, go slowly so the water will go down the drain tube without overflowing. Don't know how you can clean the outside coil ( condenser) if you can't get to it. You may just have to put the whole unit out of the sleeve and take it outside to work on it. May need to get a friend to come over and help put the unit. Good luck.
Unless directly sprayed on grass any residual spray should not be harmful
Yes but I use every 4 to 6 months to keep clean.It does not go bad.
i think you can if it is dirty just wash it out
I used it on my a/c heat pump coils and it did a good job.
Yes it will clean the tray and line.
