Apparently you can’t block airflow with a Heating and A/C unit.
Dad put us to work to find up-to-date homes for the junk that was cluttering the air flow. As he was doing his inspection he pulled out our air filter, it was filthy and really hadn’t been changed since the last Heating and A/C repair call a year ago. The little old guy just shook his head and went out to his A/C and Heating van to grab a couple of up-to-date air filters, several for the A/C and 1 for the furnace. Dad called the lawn guy to come over and trim around the s outside while the little old farty guy started going through options for a up-to-date A/C component with Dad. I went skiing. When I came home for dinner almost everyone was rejoicing at the up-to-date A/C component enjoy it was the birth of their first child. Dad was all smiles and mom romanticly supporting his happiness and his way of showing he was proud of the up-to-date member to our family. Dad came over to supply the announcement of the AC’s birth as all of us entered the living room and proceeded to tell us about the need to do proper repair with a qualified A/C serviceman with a fantastic dealer. He gripped only briefly about the cost however raved about our farty little old A/C repairman enjoy he was his son. Both of us got that it was a fantastic thing to do repair however what all of us got more was that dad & mom were able to come up with the money with no worries to repair the A/C system.
