• Very loud and obnoxious
  • Rattles around all day and night
  • Frequently fills your home with stinky gas
  • Works inefficiently and wastes money—lots of it
  • Receives regular visits from the repair guy
  • Sputters and wheezes while working
  • Often refuses to show up for work at all

If any of these describe the actions of your heating and cooling system, then it’s a Klunker all right. And it’s time you gave it a rest!
