    The 4 ton won't be over sized because it's a two stage unit. In fact it'll spend most of its time operating as a 3-ton and then upstage to a 4-ton when Btuh demand is high. The geo will feel...

    Have them supply you with a copy of their Manual J report and the design loop temp. It'll show a sensible and latent load for cooling. The sensible controls the house's temp. the latent controls...

  21. 2-stage vs single stage

    I agree that you won't know if you'll get a decent pay back without an operation cost calc. The 2-stg will provide more comfort due to the longer run time. Is the compressor a 2speed or Copeland...
