Advice please >installing central AC Hi vel, should system include reversing valve for heat pump???
Installing 2 zone central AC on old house with steam heat- Unico air handlers and Lennox xc14 outdoor units. 2 ton downstairs, 4 ton on third floor. Current quote is for AC only. Current steam heat works well -has massively oversized 50 year old boiler. Contractor says AC system alone will probably be a bit more reliable than using a heat pump. Quote started with 14acx compressors until I pointed out the longer warranty and quieter unit. Contractor seems like a good guy.
Would it make sense to go to xp14 units and get some heating use on 50 degree days?? I know we don't talk; price, but as a percentage I would not think the xp14 would be much more than an xc14. Is a heat pump system much more complex than an AC only system? Please help
