I am building a new home and am going with a hybrid (dual fuel) heat pump with a variable speed, high efficiency gas furnace for low temps. I am trying to decide whether to go with the Lennox dual stage compressor or the single stage compressor on the AC side. My builders HVAC guy suggested staying away from the dual stage due to the fact they are more expensive to repair should it be necessary. This kind of surprised me as having gotten bids from other HVAC contractors, they have all steered me towards the 2 stage compressor. Any help would be appreciated.
