I was able to get the LCC reanalysis completed before I initially told you.

The attached tables and figures are for 3-ton split system central air

conditioners and heat pumps. The incremental manufacturer costs have

been increased. by 10 times their previous values. Retail costs have been

generated with markups that are identical to the previous (non-altered

manufactures- cost) analysis. Installation and maintenance costs are

unchanged as well.

Let me knout if you have any questions.
