I have to submit report tonight. I need an age for condensing furnace TempStar serial # N9MP1D80F16B1 and Air Conditioner KeepRite serial
I get 1982 for air more shortly
no luck on furnace Roy
When in doubt - refer them to a distributor or dealer for that kind of info.
Tempstar is made by International Comfort
