I want to tell you that I am super impressed with today’s central heating and air conditioning systems. They are so much better than the central heating and air conditioning systems of even 10 years ago. Heating and cooling technology has changed so much and has brought so much to the table. Radiant heated floors as well as heating and cooling zone control (also known as zoned heating and air conditioning systems) are 2 of my personal favorites and really amaze me! Who would have thought that you could actually have heating coming out of your floors all mostly generated from hot water pipes? That is like a major energy saver. If they would only make them cheaper everyone would have radiant heated floors and put the energy companies out of business eventually for the most part. And that would be a great thing with the high cost of energy use these days. Then you have heating and air conditioning zone control or zoned heating and air conditioning systems. This is where you can have different temperatures with several thermostats throughout your home as if you had a single central heating and cooling unit for every single room. But the fact is there is only one heat and air conditioning system running it! These are high in energy use but are a great thing if you have a house that has uneven temperatures and needs indoor climate control that would be impossible otherwise. Today’s heating and cooling is simply amazing!
