The world is a technological whirlpool. TEchnological gadgets and inventions are always swirling all around us. Sometimes it is hard to keep up with everything. Cars practically drive themselves, you can talk to your phone and have it translate your words when you travel. Even heating and cooling technology is getting better and better every day. When my mother was young and starting out in the world, the most advanced form of air conditioning was the window a/c unit. Those still exist, of course, but nowadays, most places only have window ac units as a backup in case the primary HVAC system needs repair. When I first ventured out on my own, central heating and cooling was the top-notch air conditioning. Now, when my kids go out looking for their first homes and begin raising their families, they will have a whole lot more HVAC technology to choose from. Nowadays, you can smart thermostats that learn your heating and cooling habits and program the a/c and furnace themselves. You can install HVAC with zone control, which can help you be more efficient and more environmentally friendly. In fact, I recently needed to have my central heating and cooling replaced, and I chose to get an upgraded unit with xone control. The HVAC with zone control has cut my utility bill by 30%! I have set up my air conditioning to only cool the vacant bedroom to 84 degrees, while the rest of the house is at 72. In this way, we don’t waste money cooling off the whole house when there is no need to. When we have visitors, I change the HVAC thermostat settings and cool off all the rooms to the same thermostat reading. I think my HVAC with zone control is great!
