no matter how many times you post that it is not an equal comparison. The humongous (actually not since you can our purchase a 24,000 btu/h window unit) simply cannot cool as much as a 2.5 ton 30 thousand , not 3 thousand btu/h) unit. Window unit will have to run twice as long to produce the same cooling. That means if the window unit has to run 12 hours every day to cool the home the central air unit will only have to run less than 6 hours to provide the same amount of cooling plus the central unit will do a better job of distributing that cooling throughout the entire home. You would have to add multiple fans to provide the same effect with the window unit.For what it's worth...
"Humongous" (1400 BTU) window air conditioner - running 24/7 - 16 centers per kWh - $171 per month.
Still less than half the cost of that 2.5 ton (3000 BTU) central unit at $400+ per month.
It's a misnomer that window units are energy eaters (many are energy efficient). And, at any rate, this issue of providing a window unit is a temporary solution until the parts for the central unit can be received.
And as for 90 degree weather causing SIDs in an infant; one wonders how ANY child in the deep south (where I live) survived when born any time during the months of mid May to mid September prior to central air conditioning.
