Extracted text: Mohamad, owner of an residential furnished apartment's in Dubai, performed an economic analysis 4 years ago when he decided to place an new eefficient central AC unit for each apartments instead of old split units windows type in each room. The estimates used and the annual worth analysis at MARR = 12% are summarized below. Two different AC brands were compared. LG York Cost and installation, $ Annual maintenance cost, $ per year -800 Salvage value, $ Electrical power savings, $ per year 25,000 35,000 Useful life, years -26,000 -36,000 -300 2,000 3,000 7 10 The spreadsheet in below sheet is the one Mohamad used to make the decision. York was the clear choice due to its substantially larger AW value, hence York AC units were installed. MARR 12% LG York Annual Repair savings Repair maintenance savings Investment Investment Annual and salvage and salvage 0$26,000 Years maintenance $0 $800 $0 $36,000 $0 $0 $25,000 $25,000 $300 $300 1 $0 $0 $35,000 2 $0 -$800 $0 $35,000 3 $0 $800 $35,000 $25,000 $25,000 $0 $300 4 $0 $800 $0 $300 $35,000 $35,000 5 $0 6 $0 $25,000 $25,000 $25,000 $800 $0 $300 -$800 $0 -$300 $35,000 7$2,000 $800 $0 $35,000 $35,000 $35,000 8 $0 -$300 9 $0 |$300 10 $3,000 $300 $35,000 AW element $6,068 $800 $25,000 |$7,025 $300 $35,000 Total AW $18,701.17 $28,499.52 During a quick review (year 4 of operation), it was obvious that the maintenance costs and repair savings have not followed (and will not follow) the estimates made 4 years ago. In fact, the maintenance contract cost is going from $300 this year (year 4) to $1200 per vear next year and will then increase 7% per year for the next 6 years. Also, the electrical power savings for the last 4 years were $31,312 (year 1), $27,565 ( year 2), $30,493( year3), and $32,903( year4), as best as Mohamad can determine. He believes savings will decrease by $3,349 per year hereafter. Finally, these 4-year-old AC units are worth nothing on the market now, so the salvage is zero, not $3000.
