It is amazing how fast technological developments are moving. There was a time when having a landline cell phone was quite a status symbol, however nowadays, maybe ninety percent of the population owns – not just a mobile cellphone – but a cellphone which is frequently smaller than its owner! The setback is that paying too much attention to these cellphones while driving, can be disastrous. I am all for new technology. It is hard to see myself using my hands to do the laundry or writing a letter to communicate, instead of by SMS, text or a cellphone call.
Heating, Ventilation, plus A/C technology is something which has come a very long way. There was a time when the window air conditioner component was ideal for keeping the house cool in summer. Then came central heating. A central Heating, Ventilation, plus A/C system can keep you cool in summer, in addition to supply warmth plus heat while both of us were in the blistering freezing winter, but before long, the ductless mini-cut Heating, Ventilation, plus A/C system came along. This form of temperature control required no ductwork, gave zone control plus better energy efficiency, with a smart control component which could be regulated from many miles away.
Not to be left out is radiant heat, the one I prefer best. Warm air is supplied to space through heated water being passed through pipes installed below the floors. I would also prefer to experience camping in style in an Heating, Ventilation, plus A/C efficient cabin, by going glamping.
