 Are you tired of being tired? Go to adventnose.com. There's unfortunately a large number of companies that if you call them for a tune-up, they will come out there. And if your air conditioner is above a certain age, regardless of its condition, they're going to tell you it needs to be replaced. The idea that every single piece of equipment over a certain age needs to be replaced is nonsense. I'm not afraid of telling someone with an old system that they can go ahead and keep running it. It doesn't hurt my bottom line. As long as I'm taking care of that person, I'm going to see them whenever it's time.
