The numbers, compiled by Stamford Public Schools director of facilities Kevin McCarthy, showed that the price to rent standalone units for 200 rooms for just one month would be greater than the cost to buy 200 window units. In January, Mahoney had asked for an estimate of how much it would cost to rent air conditioning units for the two hottest periods of the school year: May and June at the end of the calendar and August and September at the beginning. The officials are hoping to add 200 window units to classrooms before the start of the next school year. Another 200 or so would be installed for the following year. The price tag for the entire rental would be $350,000 for one month. In comparison, buying and installing 200 window air conditioner units would cost $300,000, McCarthy said.
