Question

Is a fan and keeping the window open a much healthier way to keep yourself cool than air conditioning?

Answer 1

I'd say it is healthier, unless you live next to a busy street. It certainly is much healthier for your energy bill. Maybe if you have an allergy like hay fever then you might want to use aircon with a hepa filter. Keeping fresh air circulating is something that air conditioning isn't good at.

Answer 2

The answer depends on several things. Is the air quality in your area good? Do you have asthma or allergies? Is it really humid outside? Do you live in a dusty area? The use of  A/C that has a good filter will 'clean' the air of pollutants, dust and allergens as well as dehumidify the outside air. On cool nights, we turn the A/C off and open the windows and use ceiling fans. We turn the A/C back on in the late morning to 'beat the heat' of the late day. It helps to keep the electric bill down this way.

Answer 3

Air conditioning gives you a filtered and clean air. Open your windos and have a fan blowing dust around and you may need a new computer at the end of the season. It is amazing how much dust is gathering inside the computer without having a fan on. Mine is getting noisier all the time and I have to clear dust from the fans inside my computer regularly.
