I have never been any good at Science and Math.

Even simple geographical directions can be a challenge , for me and I was the last among my peers to learn to read the clock.

As a kid, I thought the clock was the wickedest, most confusing thing ever invented. I don’t have a scientific mind or a head for figures, clearly. That is probably why I am so impressed by modern inventions and the people who invent them.Take the HVAC industry for example. Years ago, you could hardly find a home with a HVAC system which did not have extensive ductwork. Now, The focus seems to be on going ductless. Ducts often tear and leak air, thus reducing the quality of indoor air being provided. The HVAC system works harder to provide air and the homeowner ends up paying increased electricity bills. All over the world, people have begun using ductless HVAC systems, as opposed to forced air which involves the use of ductwork.According to their inventors, ductless HVAC systems provide perfect air quality and are superior in terms of energy efficiency. Comparatively, ductless HVAC are more compact and easier to install. There is the outside condenser and the indoor cooling/heating unit, with a pipe between the two. During warm weather, the system collects the warm air from inside and channels it outside. It does the opposite in warm weather, so the heat exchange is self-explanatory. I think these arguments are most compelling but in this case, it’s like preaching to the converted: We already have a ductless mini split system at home!
