AC Ghostbusters: Science vs. Myths

 During this season of witches and ghosts, the myths about air conditioning make a comeback too. Today we’re shedding some light —and not from pumpkins— on what’s true, what’s legend, and how to use your AC without scary surprises on your bill or your health, with Thermoaqua.

Air Conditioning Causes Colds

The classic one. Colds are caused by viruses — not your AC. What can happen is that cold or very dry air irritates your mucous membranes, making you feel more vulnerable.
Thermoaqua Tip: Keep the temperature moderate (23–26 °C in summer, 19–21 °C in winter) and relative humidity around 40–60% (use Dry mode or a humidifier if needed). That way you won’t turn your living room into an igloo… or your throat into a desert.


Sleeping with the AC On Leaves Your Throat Dry

It’s not the AC itself, but extreme settings (very low temperature, air blowing directly at your body) and dirty filters.
Thermoaqua Tip: Change the spell — use Sleep mode, aim the louvers upward, and set gentle airflow. And please, clean your filters regularly (every 1–3 months). You’ll discover the “monster” was just dust. Avoid going below 22–24 °C on mild nights.


Turning It On and Off Saves More Than Keeping It Stable

Imagine a vampire going in and out of his coffin every five minutes: he neither rests nor flies better. It’s the same with your AC. Inverter systems don’t suffer big spikes and work best with steady settings. Forcing short cycles only hurts efficiency and comfort.
Thermoaqua Tip: Go for stable settings and programming (use the timer or a smart thermostat). Turn it off if you’re gone for more than 1–2 hours; for shorter absences, just lower the load (Eco mode).


Dry Mode “Cools Less but Uses the Same Power”

Dehumidifying can improve comfort without dropping the temperature as much — and sometimes even reduce energy use. Used wisely, it can be your ace up your sleeve on humid nights. If your sheets feel sticky, try Dry mode before summoning the 22 °C spell.
Thermoaqua Tip: Alternate between Cool/Dry depending on the weather and how humid it feels.


The Colder the Setting, the Faster It Cools

If only! The setpoint isn’t an accelerator — it’s a destination. Setting it to 17 °C won’t make the compressor run faster; it’ll just make the room too cold… and your bill terrifying.
Thermoaqua Tip: Set the temperature 1–2 °C below your comfort goal and wait for it to stabilize.


“The AC Uses What It Uses” — and I Can’t Change That

Good news: you’re in control. Clean filters, sealed doors and windows, closed blinds, and annual maintenance can cut your energy use more effectively than any spell.
Thermoaqua Tip: Do an autumn check-up — small habits make a big difference: less noise, stronger airflow, and a compressor that won’t need resurrecting every season.


Anti-Broomstick Checklist

  • Clean filters and vents free of decorations blocking airflow.

  • Use Sleep/Auto mode at night.

  • Pre-schedule cooling before arriving home.

  • Moderate setpoints and louvers not blowing directly on you.

  • Professional annual maintenance.
