No—in fact, the opposite is true. A well-maintained air conditioning system improves air quality by filtering out dust, bacteria, and mould. Problems usually arise when systems aren’t cleaned regularly, allowing bacteria and fungi to grow on the coils and filters.
Outdoor units, especially on rooftops, can suffer from rust or damage if left unchecked, and components like drain lines and condensate pumps need maintenance to avoid blockages or leaks. Regular servicing keeps everything clean, safe, and efficient.

Not at all. Maintenance is essential to keeping your air conditioning system running efficiently and extending its lifespan. Regular checks help prevent costly problems like:
For a relatively small cost, maintenance keeps your system in top shape and saves money in the long run.
No—this is a common myth. Air conditioning is one of the most cost-effective ways to heat or cool a home. Unlike electric heaters, which are around 100% efficient (1kW in = 1kW out), modern inverter air conditioning systems often achieve 300–400% efficiency.
That means for every 1kW of power used, you get 3–4kW of heating or cooling. More comfort, lower bills.
Not necessarily. The system can only save energy if it’s used correctly. Setting the temperature too low (e.g. 18°C) forces the unit to work harder and run longer. For comfort and efficiency, keep your settings around 21–23°C.
Many systems include a “Powerful” or “Turbo” mode to cool or heat quickly—use that to get the room comfortable fast, then let it maintain the temperature efficiently.
Nope. A unit that’s too large will cycle on and off too quickly, causing temperature swings and overly dry air. A too-small unit will struggle to keep up, running constantly and wearing itself out.
Getting the right size unit for the room is crucial, which is why a professional quote and installation is always the smart choice.
No—air conditioning systems are meant to be used. Like a car, they have moving parts, refrigerant, and oil that need to circulate. Leaving the system idle for too long can lead to seizing or performance issues.
Even if you don’t need it, it’s a good idea to run your system occasionally—just to keep everything in working order and avoid surprises when summer hits.
Absolutely. Your system needs good airflow—air in and air out—to operate properly. Installing an indoor unit in a tight corner or where airflow is blocked by beams or furniture can cause:
Proper placement is key to keeping your system efficient and effective.
Nope—not even close. Modern systems offer heating, cooling and dehumidifying modes. They can improve comfort year-round, help with damp problems, and make the air feel fresher even when you don’t need cooling or heating.
Think of it more as climate control, not just a cooling system.
In the short term, yes—but long term, probably not. Budget units may work for a couple of years, but they often wear out quickly, need parts that are hard to find, and are less efficient, which drives up your energy bills.
Eventually, you end up paying for replacement units, extra installations, and higher running costs—spending more than if you’d gone with a quality unit to start with.
Air conditioning uses electricity efficiently, which lowers your carbon footprint when compared to electric heaters. But yes, it does use refrigerant gases, which are harmful if released into the atmosphere.
The good news? AC systems are sealed, so the gas circulates inside the system and doesn’t escape—unless there’s a leak. That’s why professional installation and maintenance are important. If a leak does occur, it must be repaired properly, not just refilled.
