Proposed Response Text:
Thank you for your inquiry about capping cooling/A/C lines and electrical lines for protection.
After reviewing your inquiry, the necessity of capping A/C and/or coolant lines to prevent contamination from entering the system – the short answer is yes, it is an included operation.

Masking & Capping Electrical Connections is NOT INCLUDED

Masking & Capping open AC & Cooling Lines is INCLUDED.

“We think about this one more like ‘Protect open hoses, lines or openings to prevent contamination intrusion.’  Mask, cap, cover, seal – whatever verb you want to use.  It’s a necessary workshop practice.  Many OEM procedures call it out and it is observed in most time studies.”
