Rule Changes

The initial concern with Heating, Ventilation as well as A/C was reducing energy costs that would in-turn, reduce pollution from the creation of electrical power.

In 1917, the “spitball” was outlawed, and this effectively ended the jobs of pitchers who depended on the saliva-laden pitch. The spitball was not needed by Bob Gibson, the Hall of Fame pitcher for the St. Louis Cardinals. Whatever he threw at batters in 1970 resulted in a 1.12 received run average (ERA) that still stands as a record. Witnesses to that season are amazed at his 22-9 record. The 22 wins were not unusual, rather it was how he managed to lose 9 games that year. The response by rule-makers was to lower the mound by various inches and reduce the size of the strike zone. This didn’t seem to affect Gibson. He won 77 games in the many years after his 1970 season, often called the greatest season by a pitcher in current history. Like the spitball rule, the “Gibson rule” shortened the jobs of several pitchers, however rule swings are the norm as conditions change and technology advances. In the Heating, Ventilation as well as A/C industry, there was a time when few rules regulated it and there was little concern about refrigerants. That changed in 1971 when the Clean Air Act (CAA) was passed authorizing the EPA to establish National Ambient Air Quality Standards (NAAQS). The initial concern with Heating, Ventilation as well as A/C was reducing energy costs that would in-turn, reduce pollution from the creation of electrical power. In 1987, the United Nations Montreal Protocol was established to protect the ozone layer by eliminating freon, the “spitball” of refrigerants with its ability to destroy atmospheric ozone. That same year SEER-10 was named as the measure of energy efficiency for Heating, Ventilation as well as A/C systems. It was the first national official for the Heating, Ventilation as well as A/C industry. The search goes on for the refrigerant that will be to Heating, Ventilation as well as A/C what Bob Gibson was to the Cardinals.
