Apparently you can’t block airflow with a Heating & Air Conditioning unit, however dad put us to work to find current 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 & actually hadn’t been changed since the last Heating & Air Conditioning service call a year ago. The little aged guy just shook his head & went out to his A/C & Heating van to grab a couple of current air filters, more than one for the A/C & 1 for the furnace. Dad called the lawn guy to come over & trim around the air conditioners outside while the little aged farty guy started going through possibilities for a current A/C device with Dad. I went skiing. When I came home for lunch almost everyone was rejoicing at the current A/C device love it was the birth of their first child. Dad was all smiles & mom lovingly supporting his happiness & his way of showing he was proud of the current member to our family. Dad came over to give the announcement of the AC’s birth as we entered the kitchen & proceeded to tell us about the need to do usual service with a qualified A/C serviceman with a great corporation. He gripped only briefly about the cost however raved about our farty little aged A/C repairman love he was his son, then the two of us got that it was a great thing to do service however what we got more was that dad & mom were able to come up with the currency with no worries to service the A/C system.
