New air conditioner or replacing an old one? Norris Electrical installs and replaces all types of air conditioning systems across Sunbury and surrounding suburbs.
A quality air conditioner installed correctly makes a genuine difference to comfort levels and energy bills. Whether you are installing air conditioning for the first time, upgrading an ageing system, or replacing a unit that has failed, Norris Electrical provides professional air conditioner installation and replacement services for homes and businesses across Sunbury and surrounding areas.
We install a wide range of air conditioning systems and work with all major brands to help you choose the right system for your space, your budget, and your energy efficiency goals.
Air conditioners typically have a service life of 10 to 15 years. When an older system starts to require frequent repairs or its efficiency has dropped significantly, replacement is often more cost-effective than continuing to repair it. Norris Electrical makes the replacement process straightforward:
Modern air conditioners are significantly more energy-efficient than units from 10 years ago, meaning a replacement often pays for part of its cost through lower running bills within a few years.
The right air conditioning system depends on the size of the space, the layout of your home, your budget, and your energy efficiency priorities. Norris Electrical helps clients navigate these decisions honestly:
Site assessment and system selection
We assess the room or area to be cooled or heated, calculate the correct system capacity, and recommend the most suitable model for your space, budget, and energy efficiency goals.
Electrical preparation
A dedicated circuit is installed from the switchboard to the installation location, including an isolator switch adjacent to the outdoor unit, prior to the air conditioning unit being installed.
Indoor and outdoor unit installation
The indoor wall unit is mounted and the outdoor unit is positioned and secured. Refrigerant lines, condensate drain, and control wiring are run between the units and connected.
Commissioning and test run
The system is commissioned, refrigerant is checked, and a full test run is carried out in both heating and cooling modes before we hand over and walk you through the controls.
Air conditioner installation involves specific electrical requirements that Norris Electrical handles as part of every installation:
If your switchboard does not have capacity for a new circuit, we will advise on what is needed before installation day.
