I consistently remember the superb old heating, ventilation plus A/C system stuff that I grew up around.
Today heating, ventilation plus A/C system has become so much more advanced I honestly do not like it as much to be honest.
Call it me being old maybe, however I would much rather have a window a/c for my cooling and a heating system or maybe even a warm water boiler for my furnace instead of having central heating, ventilation plus A/C system. I find central heating, ventilation plus A/C system to be so much of a hassle to handle. With all the stuff you have to do just to maintain a central heating and a/c not only does it cost a ton of money in the long run, but it is just too much to remember to get done in the first locale! Then if you forget what ends up happening is the central heating and a/c risks splitting down. I can not remember to get my central heating and a/c unit tuned up and checked up 3 to 4 times per year. Then on top of that having to get the HVAC duct cleaned all the time is another headache and another few hundred bucks or so. With a heating system, warm water boiler and window air conditioning system unit you need not ever worry about that stuff. I wish all of this was the way it still was. But time moves on and many things change. And this goes triple for heating, ventilation plus A/C system equipment!
