Experienced and qualified installers usually take somewhere around 3-4 hours for a straightforward back-to-back (where the indoor unit and outdoor unit are positioned directly opposite each other on the interior and exterior of a wall) Heat Pump installation. More complex Heat Pump installations will take a bit longer.
Ducted systems can take between one to two days depending on the amount of spaces to be ducted. Installing a Heat Pump is a complex process requiring qualified trade professionals so must ALWAYS be undertaken by a reputable accredited installation company.
