You said 96.6 % Carrier is great . Only one unit a 38000 Btu MVP has
96.6% the rest are lower.Lower than Armstrong to. Carrier is
deceiving you . Its not a matter of who is right but that Carriers adds
are deceiving. I had 2 salesman out Both said would I like the 96.6
unit I said fine but its not made in a unit larger than 38000 btu
unit. And I need 75000 One guy left in embarassment when I pulled out
a spec sheet . Its a sales pitch, get it. There are others out there
just as good. and better in AFUE.
