There has been plenty to witness & experience over the 77 years that I have been alive.
Lots of changes have happened over the course of the past 77 years.
When I was born, residential Heating, Ventilation & A/C as both of us assume it didn’t absolutely even exist. There were heating units & there were fans for the summer. Recently, an Heating, Ventilation & A/C experience at one of my children’s lake house absolutely brought that all back to me. My oldest built a beach house now that her youngest is off to college. The beach house is absolutely well thought out & quite sustainable. To that end, the heating & cooling machine is also state of the art Heating, Ventilation & A/C technology that looks to be entirely efficient. My daughter’s current lake house uses a geothermal heat pump to both heat & cool the house. A geo heat pump uses a long tube buried under the ground to extract heating & cooling energy. This Heating, Ventilation & A/C technology uses the near constant temperature of the earth as a most consistent source of heating & cooling energy. While more valuable on the front end, the geothermal heat pump will supply significant heating & cooling savings for the next 30 plus years. What blew me away & took me back to my youth was the radiant floor heating. The two of us had radiant heat from a boiler when I was a little girl & that radiant heat is the most comfortable I’ve ever felt. The fact that the heat comes up from the floor is even better than the radiators both of us had when I was growing up. It’s amazing how things come full circle.
