(The Rankine scale uses Fahrenheit-sized degrees and absolute zero as zero, with ice melting at 460R and water boiling at 640R, but almost nobody uses Rankine anymore, so you are welcome to forget you ever heard about it.) As a general rule, little or no permanent deformation (creep) occurs when the temperature (in Kelvin or Rankine!) is less than about half the melting temperature, and creep occurs rather easily when temperatures exceed about three-quarters of the melting temperature
Ideally, your AC and heating system should be professionally tended to twice a year to extend their life span, reduce utility costs, prevent future breakdowns, optimize temperature regulation and prevent unwanted chemical odors
