The AC has quit working at my friend's daughter's home.
I don't know whether they were running central AC or a window unit.
My friend has picked up a large used window unit at no cost.
I helped him load it into his van, and asked whether there was a window large enough to accommodate it.
He replied that he doesn't need one - he plans to install it in the basement, with the cold air output plumbed into the existing ductwork, and the hot exhaust air ducted outside.
I doubt this will work properly.
Concerns:
1. The unit's blower fan will not be powerful enough to exhaust the hot air - an inline booster fan will be required.
2. The cost of the sheet-metal work would be prohibitive.
3. The footprint of this installation would be large.
4. Condensation would have to be gathered in a pan and emptied regularly. The exhaust ducting would have to make allowance for this.
5. This unit will be very expensive to run (1170 W/10.9 A on 120 VAC, SEER 10.8, 12,600 BTU/hr) plus the cost of running a booster fan and the furnace fan.
My preferences would be:
A. If the existing broken system is central, repair or replace it.
B. If the existing system is a window AC, replace it with a modern SEER 18 (or better) unit.
If required, run a dehumidifier as well.
C. If this old free unit must be used, cut a hole in the wall (properly framed with a header, etc.) and install the AC unit as it was designed to be installed.
Thoughts? Thanks.
