It still sort of blows my mind all that I’ve seen take arena technologically during my lifetime. And I’m only 55 years old. It’s been particularly sort of staggering just where we’ve come since I was in highschool. My highschool didn’t even had central air conditioning. There was radiant heating in the winter time plus then nothing. It could get sweltering prior to school being let on for the Summer. Now, I hold an amazing laptop in my hand plus also use it for a iPhone plus a camera. Then, I know about my dad. This woman grew up way down south separate from any sort of residential HVAC. And if you’ve ever been through one of those Summers, you’d understand just how strenuous that would be. I don’t live that far south plus I can’t imagine what I’d do separate from central air conditioning much less any residential HVAC. But the heat pump has come a long way. While it’s still such a magical mixture of genius engineering plus physics at it’s basic form, innovations have pushed HVAC technology. My buddy and I updated the heat pump last year plus the SEER rating alone was more than three times what it was on the old one. That’s all due to advances in HVAC technology. Now, I have a smart thermostat which precisely manages that residential HVAC so the efficiency these afternoons is simply remarkable. That saves me money as cooling a apartment can get lavish separate from enjoyable efficiency. For people like my dad, the best she could hope for was a arena under the fan inside, and or maybe a enjoyable afternoon breeze plus a shady spot under plus oak tree, then yea, residential HVAC has come a particularly long way.
