New Zealand summers have a way of testing patience. One minute, you’re enjoying an ice-cold drink in the shade. The next, you’re sticking to the couch, wondering if you can sleep in the fridge. When the heat kicks in, most people turn to one of two things: a trusty fan or a proper air conditioning system.

Fans have been around forever—cheap, simple, and just effective enough to trick you into thinking they’re doing something. But are they actually keeping you cool, or are they just moving warm air around and hoping for the best? Let’s settle this. 

 

Why Do People Still Use Fans?

Fans have a loyal following. Some households treat them like family heirlooms, dragging out the same rattling pedestal fan every summer. The logic? Fans are cheap, easy, and “just as good” as air-con—except they aren’t.

A few common myths keep fans in the game:

  • “Fans cool you down just fine.” Not really. They don’t lower the temperature; they just push air around. If that air is hot, you’re just recycling the problem.
  • “They’re cheaper to run.” They use less power than air-con, but they’re also less effective. Running a fan all night while still feeling overheated isn’t exactly value for money.
  • “Air conditioning is too intense.” Some worry about air con being too cold or drying the air. The reality? A modern system is designed for efficiency and comfort—you’re in control of the settings.

For all their quirks, fans can be helpful in mild conditions. But when the heat gets serious, they don’t provide the cooling that most Kiwis crave. 

 

The Problem with Fans 

The hard truth? Fans aren’t just ineffective, they can sometimes be detrimental. As we’ve established, fans work by pushing air around. That airflow helps sweat evaporate, creating a cooling effect, but when the surrounding air is already hot, all you’re doing is circulating warm air like a convection oven.

In fact, research from the U.S. National Institute for Occupational Safety and Health (NIOSH) suggests that when temperatures reach 32°C or higher, fans can increase the risk of heat stress rather than prevent it. Why? Because instead of cooling the body, they push hot air against the skin, making it harder to regulate temperature and increasing dehydration. 

And what about using a fan overnight? That’s when things get even more uncomfortable. A constantly running fan dries out your nose, throat, and skin, potentially triggering allergies or sinus irritation. On the other hand, air con and heat pumps can be good for allergies because they actively filter the air, removing dust, pollen, and other allergens rather than just blowing them around. Modern air conditioning systems come with advanced filtration, such as HEPA or electrostatic filters, which capture airborne particles that trigger sneezing fits and itchy eyes.

 

The Benefits of Air Conditioning

If fans are the outdated flip phones of cooling, then air conditioning is the smartphone—sleek, efficient, and something you’ll wonder how you ever lived without. Unlike fans, air conditioning doesn’t just shuffle warm air around; it removes heat, bringing the temperature down to a comfortable level. But cooling is just the beginning.

  • Humidity Control – New Zealand’s summers aren’t just hot; they can be sticky and unbearable. Air conditioning reduces excess moisture, preventing that unpleasant damp feeling.
  • Better Air Quality – A good air conditioning system filters out dust, pollen, and pollutants, making it ideal for allergy sufferers or anyone who prefers breathing air that doesn’t feel like it came straight from a bus exhaust.
  • Energy Efficiency – Modern heat pumps and air conditioners are far more efficient than old-school models, using less energy to cool your space effectively. No more running a fan all night and still waking up drenched in sweat.
  • Year-Round Comfort – Heat pumps can warm your home in winter, too, making them a smart, all-season investment rather than a temporary fix.

At the end of the day, an air-con system isn’t just about staying cool—it’s about comfort, health, and a home that actually feels liveable, no matter the weather.

 

A Comparison at a Glance 

Alright, let’s break it down. If we put fans and air conditioning head to head, the winner is pretty clear.

 

Feature Fans Air Conditioning
Actually lowers room temperature? ❌ No ✅ Yes
Removes humidity? ❌ No ✅ Yes
Filters air/allergens? ❌ No ✅ Yes
Comfortable for sleep? ❌ No ✅ Absolutely
Cost-effective in the long run? ⚠️ Debatable ✅ Yes

 

As you can see, fans do something—but not much. They create the illusion of cooling without actually changing the temperature, making them a short-term distraction rather than a real solution. Air conditioning, on the other hand, does the job properly—cooling, dehumidifying, and filtering the air so you’re not just surviving the heat, but actually comfortable in it. When it comes to long-term value and actual relief, there’s no real competition.
