Check the prices, I think some have come down. It's installation that's the killer. Wish I could do it myself.
Just bought a bagel with cream cheese and when I get back to the office and pull it apart, most of the cream cheese is stuck to one side. Day isn't starting off great.
Split unit was around $1000-1500 installed for us. Seems to be around $3k to add coils and a compressor for our whole house.
Was that for one room? That's in the ballpark on an estimate a local HVAC guy gave me for our bedroom. (10 years ago he told me $15,000 to do the whole house.). I'm just sick of buying cheap window units that go bad after three years.
