Air conditioning

Gold Coast Electrical provides professional installation of air conditioning units to residential, commercial, schools, retail environments, showrooms, and offices.

We have the required facilities and qualified team to design and install systems to suit your needs.

Split system air conditioners

A split system air conditioner is the ideal affordable option. It consists of an indoor unit, connected through refrigeration pipework to an outdoor unit, allowing you the freedom of placement.

Their flexible design offers you a wide range of choices for the perfect solution to your air conditioning and heating needs.

Split system AC benefits:

  • Affordable and reliable

  • Individual temperature control to each room

  • Quiet operation

  • Fantastic energy efficiency

  • Low maintenance

Finding the right size air conditioner

Use the chart below to approximate the required cooling and heating capacities for differently sized rooms:

Room size m² capacity

Cooling (C)/Heating (H)

3.0m x 3.0m = 9m²


5.0m x 5.0m = 25m²

3.5kw(C)/3.7KW – 4.3KW (H)

5.5m x 5.5m = 30m²

3.5kw(c)/3.7KW(H) – 5.0KW(C)/6.0KW(H)

6.3m x 6.3m = 40m²

5.0KW(C)/6.0KW(H) – 6.0KW(C)/7.2KW(H)

6.7m x 6.7m = 45m²

6.0KW(C)/7.2KW(H) – 7.1KW(C)/8.0KW(H)

7.1m x 7.1m = 50m²

7.1KW(C)/8.0KW(H) – 8.0KW(C)/9.0KW(H)

7.7m x 7.7m = 55m²

8.0KW(C)/9.0KW(H) – 9.2KW(C)/10.0KW(H)

Energy saving tips

With rising power costs, it’s more important than ever to adopt smart behaviours to increase your air conditioner’s efficiency.

Increasing the efficiency and effectiveness of your system will prolong the life of your air conditioner and ensure optimum operating conditions.

Optimal set temperature

Setting your system to cool to 18° will not cool any quicker that setting it to 24° on a hot day.

A setting of 18° will have your system working longer to achieve a temperature that may not be reachable. Also try setting your system to 25° compared to 23° or 24° during peak conditions. Each degree you raise your setting will increase the efficiency of your system.

Take control of heat loads

Do your best to control excessive heat into your conditioned space. Closing window coverings, blinds and awnings will reduce the amount of heat transferred into your home. If you have a ducted system, closing zones and doors to unused areas will increase efficiency.

Use the cooling or heating mode

Most air conditioning systems have an ‘Auto’ mode which cycles the system between cooling and heating. This function can sometimes switch to either cycle, especially during a change of season, keeping the motor under load. It can also lead to some confusion in the general setting for the operator.

We recommend you set your system to “Cooling” during summer months and “Heating” during winter months.

The simple things

Keep your eye on the weather forecast. If you know it is going to be a hot day, and you are going to be at home, turn on your system in the morning rather than waiting until you feel the need to. It is easier for your system to maintain your desired temperature than for it to work hard to achieve that temperature.

The same principle applies to leaving your home. If you are only heading out for a short period, leave your system running rather than switching it off. Once again, your system will find it easier to maintain the temperature rather than letting the home heat up and then converting the temperature back to your set point.

Regular maintenance

Regular preventative maintenance inspections will ensure your system is operating under its optimum conditions. A dirty filter can affect airflow and refrigerant running pressure, causing increased power consumption.

We recommend that your filters be cleaned every three months. A domestic air conditioner should be maintained by a professional at least once a year, while commercial systems will vary depending on the application.
