Should I replace my furnace?
Think of investment options. Stocks, bonds, mutual funds, money market, 401k, 403b, annuities, IRA, life insurance, real estate, egads!
The choices of investment options to earn money are endless. Wall Street finance lingo mixed with risk and uncertainty can be overwhelming! So what is a really good investment with an assured strong return?

Pay off those high rate credit cards? You bet! The guaranteed ROI (return on investment) can be significant. What about a savings account or CD offering an assured ROI at a pretty low rate?

How about investing in a hard necessity that can yield a very attractive ROI?

No fancy Wall Street words, just simple math. A new Armstrong or Amana furnace could save $320 or more on an annual heat bill of $2000 with an investment of $2,800*! The ROI is a pretty fair 11.4% when you divide the annual cost savings of $320 by the initial investment of $2,800*.

In nine years time this $320 annual savings becomes $2,880* – more than the cost of the new furnace! That doesn't account for any repair costs for the old furnace in the next nine years.

These numbers are based on replacing an 80% AFUE furnace with a new 96% AFUE Amana furnace and taking the generous manufacturer rebates and Focus on Energy rebates.
