Today I ran a system check on my furnace for the first time, a Carrier 80% two stage (54k btu output on high and 36 k output on low, oversized I know, but about as small as I could get, and probably does not matter much as the heat pump generally runs except during morning warmup) installed with a two ton heat pump for dual fuel. It has an infinity thermostat and reports air flow cfm, motor rpm, and static pressure.
First, are the numbers reported by the system generally reliable? Do ya'll go by them when they are available on the thermostat, or do you always take your own readings?
My numbers were
Low heat: Air flow 633 cfm, motor rpms maxed out at 654, and static pressure bounced between .27 and .28.
High heat: Air flow 1033 cfm, motor rpms 1133, and static pressure of .78.
Are these normal, acceptable numbers?
