Temperature of Furnace

I have a Goodman Furance and A/C unit. Recently we had a bad thunderstorm that took out my circuit board and pressure valve/switch. All is working now, but the air coming out of the vent is not as hot as I used to recall. the house warms up, but the air coming out is just not as hot. what is the temperature out of the vent suppose to be? It seems just warm, rather then hot. Is there something that the repair tech did not tune? Also the amount of air out of the vent is not as much as it used to be also. Thanks.
