Furnace Emergency Safety Update

The phrase, "In fact, most furnaces die in middle age" is one example of personification. "I'll actually make money on this in the long run anyway" is an example of a metaphor.

A few things come to my attention while reading this. The first is the author's credibility. The whole offer makes me a little skeptical. It really just seems like it is too good to be true. The author does a good job at making his case. He points out all the benefits of his service and mentions his competition's higher prices. To top that he even goes as far as making a risk free money-back guarantee. These are all good things for the consumers, but something just isn't right about the situation. It is almost as if the author is a bit too biased, which we would expect I suppose. However, I do believe there may be details the author is leaving out.

Another thing that came to my attention was when the author mentioned how his business is slow in November. Being a heating company would make me suspect that November would be a pretty busy month since that is about the time everyone usually starts looking into heating their houses. I also don't quite understand how stripping out everything except the raw costs of the company would be a wise idea. If the author claims November is a slow month, how can he afford to pay is technicians and still offer such a great deal?
