Case Study: Typical Installation in an Eltham Home

Consider a mid-terrace house in central Eltham. The homeowner wanted a wall-mounted air conditioning unit in the living room. After a site survey, the installer recommended a discreet location above a side window, keeping the unit out of direct view from the street.

The outdoor condenser was mounted on the rear wall using vibration-dampening brackets to reduce noise for both the homeowner and neighbouring properties. The project was completed without the need for planning permission, and the family now enjoys efficient cooling throughout the summer months.
