People have different opinions when it comes to, well, everything. Including heating and air conditioning, as I found out a few days ago. My friend and I talk about all kinds of weird subjects, and a few days ago we were talking about different types of heating and cooling devices. I am not sure how we even got on this subject, but we started talking about HVAC technology. We were in agreement about everything until we reached the subject on what kind of HVAC equipment is better, that is when we started disagreeing. My friend went on and on about how much better central heating and air conditioning was, and how it is the most popular form of HVAC because of that. But honestly? I disagreed. I knew that the central cooling device was far more common, but I liked zoned heating and A/C. A lot of disputes over the thermostat or over the heating and cooling systems can be settled with zoned HVACs. Zoned heating and air conditioning is probably less common because it is expensive, but in my opinion it is definitely worth it. My wife and I love our zoned air conditioner, because we can have whatever temperature we want, and not be uncomfortable. But my friend doesn’t think highly of the zoned A/C device. He enjoys the central air conditioning and has had it all of his life, he said that it has never let him down and he never wants to get a different system. To each their own.
