I have some quotes for the Mitsubishi Zuba system for our house and I have a few questions:
1 - from anyones experience, will the system work well on a 33 year old brick raised bungalow of 1,110 sqft and a heat load calc of 44,000 (ish) btu/h? The windows are mostly new, and the attic has been insulated from R11.9 to R50+. From what I have read online, it should be fine but...
2 - for the size of home, again from what I have read here, should I be getting an estimate on a York system as well?
3 - does anyone have one installed where I could get some info on yearly heating cooling costs and type/size of homes installed?
4 - what kind of longevity will the Mitsubishi's have? Similar to the r12 Ac units that ran for 20+ years? Are the heat pumps from York etc as good as they used to be?
Thanks a lot for any help, its just after years of living with a FAG system, and all the NAY sayers out there against the heat pumps, I need a little confirmation... of course the estimators said no problem, but I would love some real world figures, and they had installed so few that they had no testimonials for it.
