Had a heat pump in Va in 1988. Nothing new.
—”Had a heat pump in Va in 1988. Nothing new.”
That is a fact!
Also any refrigerator, freezer, AC unit... is a heat pump.
What has changed by leaps and bounds is the performance.
Even 10 years back not suitable for much north of the Mason-Dixon line.
My unit is rated for MINUS 13 F. and can kind of sort of do it here in northern Illinois.
