We had a unit for years, it was recently upgraded when I was about to graduate from high school, but I heard my mum say that the unit had been serving us for years, dad interjected and confirmed that it had been approximately twenty years since the air conditioning installation was done. The Heating and A/C unit had served us well as I only saw the air conditioning technicians once a year or occasionally twice when we were on spring break or during fall. There was a dial thermostat mounted on the wall in the corridor. This was a good spot as the regulator is not meant to be located somewhere where there is direct sunlight as it will provide incorrect readings. The unit had come to the end of the road. It’s years had been spent, my dad had ordered a new air conditioning from the air conditioning company at the local supplier and dad was excited as he had received a discount for being one of the 100 customers to purchase the all-new ductless multi-split. The a/c workman was impressed with the condition of the old unit as though it was old, it looked new because our parents had adhered to the proper air conditioner service that is required to enhance the function of any unit. The experts had just come from installing another commercial air conditioning in the new commercial building in town. Since they knew more about air conditioning, the experts suggested that the two of us continue scheduling proper air conditioning service to enhance the function of the unit and reduce the repairs. After all this was done, I asked the specialist why they were not increasing the regulator to which he answered that the regulator was still functioning and there would be no need to change it.
