We do all work ourselves so we wouldnt hire a contractor, I found a Williams Floor Fur on Ebay for 595 and bought it only to find out it was pick up only in Philadelphia. Cant do that. So I contacted you for your input. I know I can order locally but thought your experience would provide a more reasonable site for purchasing.
sorry had to step away for a bit
williams has a good model, so doesnt cozy and empire
however, I am not sure your location but I would try to stay away from purchasing used as you never know what you get. You may find a cracked heat exchanger in which you have wasted your money.
I have never used the williams brand but my supplier deals with the cozy and empire units in which I have been satisfied. Cozy is a bit better efficient than the empire units in my opinions
I see that for 1100$ williams does have a brand new unit.. empire has them for $1200 for a 45,000btu through grainger
