A small heat pump, including the duct system, now costs $2,800 to purchase and install. It has a useful life of 12 years and incurs annual maintenance expenses of $75 per year in real (year-zero) dollars over its useful life. A compressor replacement is required at the end of years 4 and 8 at a cost of $600 each in real dollars. The annual cost of electricity for the heat pump is $720 in year-zero dollars. Electricity prices are projected to increase at an annual rate of 9%. All other costs are expected to increase at 4%, which is the projected general price inflation rate.
