Mohamad, owner of an residential furnished apartment's in Dubal, performed an economic analysis 4 years ago when he decided to place an new eefficient centrat AC unit for each apartments instead of old split units windows type in each room. The estimates used and the annual worth analysits at MARR = 12% are summarized below. Two different AC brands were compared. 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 vear and will then increase 7% per year for the next 6 years. Also, the electrical power sevings for the last 4 years wore $31,312 (year 1), $27,565 ( year 2), $30,493( year3), and $32,903( year 4), as best as Mohamad can dotermine. He believes savings will decrease by $3,349 per year hereatiet. Finally, these 4 -year-old AC units are worth nothing on the market now, so the saivage is zero, not $3000. 91 - With these new estimates.
