For just a furnace Frank??? That sounds like they are screwing him! Most furnace's are around $3,000 installed? Roughly of course! Have your friend get a couple of additional estimates to make sure that price is in line???!!!
Sounds like a lot unless it's a big job or complicated install. Ours was about $5,500 for a top end Buderus unit with a stainless hot water tank added as a 5th zone.
Thats a nice unit Spence and alot more reasonable price! Alvin Hollis likes to "hold up" its customers as they feel they are a captive audience with no options! Frank.....make damn sure your friend fields at least 2 other estimates for the job!
