Detailed HVAC install — complete setup of a residential air conditioning system. This time, we started the installation in a new-construction home where the refrigerant lines had already been run by someone about two months ago. From wiring and drain connection to brazing and pulling vacuum before startup — every step is shown in detail. Real job footage for those who enjoy watching the full AC installation process — from attic work to outdoor unit setup. #HVACInstall #ACInstallation #Refrigeran
