Electrical servicing

Electrical servicing jobs can include changing plugs, powerpoints, appliance testing, test tagging, hot water systems, wiring and rewiring, kitchen lighting, dining lights,  dimmers, installing LED’s, pendant lighting, smoke detectors, landscape lighting, sensor lights, deck lighting, soffit lighting, security lights, security alarm systems, cameras, installation of heatpumps, bathroom fans, ventilation, under floor heating, spa pools, pool pumps and all your home electrical needs.

Have you got enough power load to your house? With years of servicing experience, knowing how much power supply your appliances will need and how much you have is key for all appliance types, for example the latest ovens, the key is to allow enough current to your switchboard for extra loads that modern appliances require.  Don’t get caught out and overload your power supply by not knowing how much current your appliances put out? Our Nexa Team can help you with all the latest requirements.

Retrofit electrical

She’s an oldy but a goody. A do-up. Moving home and renovating. Worst house, best street. Feel like a change.

Where to start?

Nexa Electrical have great advise when it comes to a retrofit.  We can have a qualified electrician come around and establish what it is you are wanting and let you know exactly what will be required. There are a broad range of questions you may want to ask us. These are just a few we get:

• What kind of wires does your house have?
• Is it a full refit of wires. Does the switchboard need replacing?
• Do you have enough plugs or do you need a couple extra?
• Would you like a sensor in your pantry and/or in your hallway?
• Where and what are the benefits of lighting and dimming?
• What size cabling do you need for your appliance capacity?
• Are you smoke alarms needing replacing and updating?
• Is there a fire hazard?
• Is your house meeting health and safety living requirements?
• Is your home heated sufficiently? We supply installation of heatpumps.
• Are your heatpumps operating at their most energy efficient capacity?

The Nexa experts are here to help and provide knowledge and key information for helping you make the best decision for your home minimising any extra surprises.
