Hello again,

Robert-thank you for your help earlier. My attic fan is fixed-you are awesome!

My new question is how/where do I find out how much space my heater will cover. I have the coleman deluxe air blend 7681-8171....? was that number correct?

My house is a 76X16 = ~ 1200sq ft. I'd like to add an addition and I'm wondering if I will need another heater source.

Any info you can offer is greatly appreciated!

Hi Anna,

Look on the furnace facing for the data sticker or nameplate to get furnace model number.

The number you gave is the blend air II model number.


You would need to have a Manual J Load Calculation done on home and addition to know what size is needed for all.

Usually when an addition is added, furnace will need to be upgraded.



Thanks,
Robert
