Question:

I was considering a Robur/Serval unit for my new house and did a Deja search.  Found some older posts complaining about the reliability (in alt.hvac).  My HVAC guy was willing to install the unit, but he ended up also hearing about reliability issues, so we decided against it. Hope this helps. Bart

With my NG furnace and electric A/C likely needing replacement in the next couple years, I’m wondering if a single NG chiller/heater is something I should consider.  If anyone has experience with small (3-5 ton) residential ammonia chillers I’d appreciate some feedback.

As Bart mentions, Robur makes one, and York used to offer the "Triathlon", an all-in-one chiller/heater unit as late as 1993.  It’s no longer offered, and I wonder whether it’s because of slow sales or technical issues. >Where are you located – what part of the country – we have had a "Gas Pack" >heat and A/C unit (Carrier) since our house was built 7 years ago!

I’m near Phoenix.  I suppose gas packs are an option, but my thought is that I may be able to consolidate 4 separate units (2 compressor A/C’s & 2 gas heaters) into 1 large roof mounted unit that supplies either chilled or hot water to 2 separate heat exchangers on each side of the house.  I’m spending about $2,000 a year to heat and cool my house and I probably could cut that in half with such a system.  Not only would I save money, but cost would likely be less and maintenance/repair would be consolidated.  Am I nuts?
