Even our new heating and A/C component is making myself and others guess old, then but that’s fantastic because this is the best quality heating and air that I have ever experienced; then that’s saying a lot because our old residential heating and A/C was top of the line when my friend and I had it installed some 25 years ago… Then that old heating and A/C component really did a wonderful job when it came to heating and cooling our home; then my youngsters grew up inside the central a/c of our house really comfortably thanks to that old heating and A/C equipment. And for that, I’m really grateful. But man, has heating and A/C technology ever come a long way in the past quarter of a century, and it’s difficult to guess it’s been that long since my friend and I had that residential heating and A/C installed in our home. Again, there are so many things these afternoons that remind myself and others that I’m closing in on 60 years old. But there are some things that get better with age. I can actually attest to the fact that the heating and the a/c in our house is far better these afternoons… Not only is the heating and cooling comfort in our house so much better but it comes at a much lower cost. The SEER rating on our new heating and A/C component is off the charts compared to the old 1. That means there is so much more efficiency built into this heating and A/C equipment, and so operating it is far less expensive than the old heating and A/C equipment. But it’s stuff akin to the zone controlled heating and A/C and the smart control component that have myself and others completely blown away. I still adore being a kid on Christmas day with some of this heating and A/C technology.
