When it comes to commercial air conditioning, there is no shortage of opinions floating around. From facility managers to business owners and even staff, everyone seems to have a theory about how to save energy or fix performance issues.
The problem? A lot of that advice is outdated or just plain wrong.
At Vartech Air Conditioning, we have been installing, servicing and repairing HVAC systems across Auckland for over 25 years. We have seen the impact that misinformation can have - higher power bills, breakdowns and systems that just do not do what they are meant to do.
Here are five of the most common myths we hear and the truth behind them.
Myth 1: "If I set the thermostat lower, the room will cool down faster."
Reality: Your HVAC system cools at the same rate no matter what temperature you set.
Dropping the thermostat to 16°C will not cool your office any faster, it will just keep running longer and drive up your energy bill.
The smarter move is to set a comfortable target (typically around 22 - 24°C for commercial spaces) and let the system do its job. With a properly maintained unit and clear air flow, you will reach your target temperature efficiently without overloading the system.
Myth 2: "Maintenance is optional - I will only call when something breaks."
Reality: Waiting for a breakdown is one of the most expensive ways to manage your HVAC system. Emergency callouts, lost productivity and short notice parts replacement all add up.
Regular servicing is the best way to keep things running smoothly and prevent major faults. At Vartech Air, we carry out full system checks including refrigerant testing, coil cleaning, fan inspections and more. This keeps your system efficient, extends its lifespan and gives you peace of mind.
Myth 3: "All air conditioning companies do the same thing - just pick the cheapest."
Reality: Choosing based on price alone is risky business. Some contractors cut corners by using lower quality parts, rushing installations or skipping safety checks.
At Vartech Air Conditioning, our team is fully qualified and we work only with premium suppliers. Every job is backed by a workmanship guarantee and we meet all Building Code and IQP compliance requirements. We are not the cheapest - we are the most reliable.
Myth 4: "If it is blowing cold air, it is working fine."
Reality: Just because cold air is coming out of the vents does not mean your system is operating efficiently. There could still be hidden problems like dirty filters, a failing fan motor or a refrigerant imbalance.
These small issues put stress on your system and lead to bigger failures over time. That is why it is important to schedule professional servicing even if everything seems okay.
Think of it like your car - it might drive fine today but you still change the oil and check the tyres.
Myth 5: "New systems do not need servicing for the first few years."
Reality: Even brand new commercial HVAC systems need regular maintenance. Dust builds up fast in commercial environments and filters can clog within months. Skipping those early checks can void warranties and lead to premature wear.
At Vartech Air, we offer tailored maintenance schedules that match your system size, building use and occupancy levels. That means you protect your investment from the start.
Knowledge Is Power and It Saves Money!
The more you know about how your HVAC system works, the better decisions you can make for your business.
That is why we always take the time to educate our clients, not just service them. We want you to feel confident that your system is delivering what it should - clean air, comfort and cost control.
