I was just quoted a couple of prices for a simple change-out, from a local Trane dealer. An XR13 unit, and an XL14i unit, both with the TWE Vari-speed AH.
Their equipment cost was the same between R410 and R22, so we got into a discussion about refer. "I wouldn't put that new stuff in *my* house..." he said. "The industry won't fully adopt R410 anyway - there so many drop-ins out there, that everyone will go with those; they're more popular".
I quoted a fact I read on Honeywell's website, about R410 being more efficient at heat-transfer; and this was confirmed by a member here. "Bah! --actually the opposite is true - I'd stick with an R22 system..." he said. He gave me prices of refer -(that I won't mention here), where R410 seemed to cost 120% more than R22.
I've got a bit of an airflow issue in my house; and if I had a vari-speed AH put in, I'd never get air in that paticular room. I asked him about the price diff. between the Trane TWE, and a single-speed unit - "I wouldn't do it.. I wouldn't put it in; you'd have to call another dealer then..." (Scare tactic?)
I can see that this contractor wants things HIS way, and not *MY* way (I'm the guy with the money...) Quote was given in writing, non-itemized. Since there was an existing unit, he didn't do a Man-J calc.
