Hi, all. We just spent money ($$$) that we really don't have on a brand new upstairs heat pump unit and blower. (old unit was 18 years old and had a leak, so...) We bought a Rheem Classic RPNL031JAZ+RHLLHM3617JA 2.5 Ton 13 SEER Heat Pump Split Air Conditioner.
At first, the blower was set so high that in our master bedroom it sounded like wind through a slightly open window in a speeding car . Also wasn't cooling to temp (though I'll admit we've had record heat indices) and wasn't dehumidifying the air well at all.
A/c man came out and adjusted the blower downward (slower), but since it's a variable speed motor, now it alternates WHOOSH-woosh-WOOSH-woosh -- as if above-mentioned car was going 60 mph then 20 then 60 then 20....and still not good enough cooling or dehumidification.
The manufacturer's rep came today with the company that installed it. They say that an additional outlet in the master bedroom and "a piece in the attic" (piece of ductwork?) will fix it. I guess that then spreads out the load of blown air so it doesn't blow so hard?
but will the dehumidification be any better? I don't care to only quiet the noise; I want better performance.
