$5600? Lucky you!
I just got a quote for a new oil-furnace & 4-ton heat-pump for my 2800 sq.foot home in Virginia Beach. The 28 year-old heat-pump died but the furnace still works OK. $15,400!!!!
Until I can get anything close to a reasonable estimate, I'll be running window units for awhile!

Happy Motoring, Mark
