FAQS

Yes. Just like a car that’s left sitting for a year may not start when you finally need it, an air conditioner that goes unused still needs regular maintenance. Dust, moisture, and wear can affect its performance even when idle. To protect your investment, we recommend servicing your cooling and heating systems at least once a year. Preventative maintenance is far more affordable than unexpected repairs or replacements — especially during peak summer months (March through August), when emergency callouts are most common.

Breakdowns can happen for a variety of reasons — from poor installation and substandard materials to lack of maintenance, electrical faults, or incorrect system sizing. Sometimes, the issue stems from bad design or choosing the wrong indoor/outdoor location for your unit. That’s why it’s so important to work with a reputable company like Robertson Air Conditioning. We don’t just have a licence — we have over 40 years of hands-on experience ensuring your system is installed correctly, safely, and efficiently.

Not often. Our customers who stay on regular maintenance programs rarely face emergency breakdowns during the hot season. Quality installation, correct system design, and routine servicing dramatically reduce the risk of failure when you need your air conditioner most.

Australia’s climate can be harsh — especially on the Gold Coast, where humidity and long hot spells are common. Most issues arise when systems are incorrectly sized (too big or too small), poorly installed, or not built for local conditions. Robertson Air Conditioning only supplies high-quality systems designed for Australian weather, ensuring energy efficiency and durability. We’ll help you find the ideal temperature range (typically between 22–26°C) and humidity balance for year-round comfort — without sending your energy bills soaring.

Humidity plays a huge role in how comfortable you feel. Even on mild days, high humidity can make you feel hotter. The right air conditioning system, correctly sized and installed, can help reduce humidity to a comfortable level. At Robertson Air Conditioning, we’ll help you choose the best solution for your space — and we’ll never push a specific brand for incentives. We recommend systems based purely on what’s best for you.

Insulation can help reduce heat gain during the day, but once the space warms up, insulation alone can trap heat inside. It won’t replace the need for cooling or heating, but it can improve air conditioning efficiency, lower energy consumption, and reduce system size and running costs. We recommend combining insulation with an efficient air conditioner for optimal comfort and savings.

Here are a few key things to keep in mind:

1. Correct capacity (kW): This must be calculated by an experienced professional who considers insulation, window orientation, and construction materials.
2. System type: Decide between split systems (wall, ceiling, or floor-mounted) or ducted systems (with or without zoning).
3. Brand selection: Not all brands have a complete range to suit every space — we’ll help you choose one that fits your needs and style.
4. Installation quality: Ensure the company installs the system themselves — not subcontractors. Robertson Air Conditioning handles every job in-house for consistency and quality.
