My good friend recently retired from many years in the heating and air conditioning business.
He was a certified heating and cooling specialist who started out working for various heating and air conditioning companies and then eventually became an independent heat and a/c worker and started his own HVAC business which grew pretty well.
Upon his retirement he threw a party to celebrate and invited all his close friends and family. I was of course one of those invited. The most amazing thing was that he always had the latest and greatest in heating and air conditioning technology and this showed even today at this party. Because he had an amazing central heating and air conditioning system that kept us all feeling the great indoor comfort while we were there. He said it was one of the newest heat and a/c units on the market and that he had just got one right before retiring. It had a smart thermostat and even smart air vents! The smart air vents were really cool to see. Because these smart air vents have a mind of their own in a way. They adjust themselves based on sensors to make the air flow work perfect as needed to keep the house all one perfect steady temperature. This is for sure the future of central heating and air conditioning I would say in my opinion! I am happy for my friend though and hope he enjoys his retirement. He sure deserves it after all the long and hard years he worked in the HVAC business.
