I am having an issue from last summer -couldn’t get the furnace to fire, it was 80F outside, furnace was 1 yr old, had a programmable thermostat that wasn’t cooperating! I reported I as unable to test, outside temp too high - see SOP 2.4E. Recommended to have a heating and cooling specialist fully inspect and clean the furnace prior to closing.
Now they are having problem with the furnace.
Actual problem was inadequate flue distribution.
Did we report this correct, and should we NOT test when ambient temp is >80F?
