Was $2225 way too much to pay for my new furnace or was it at least somewhat on key to the norm?

DEPENDS ON WHERE YOU LIVE, AND WAS ANY AIR CONDITIONING EQUIPMENT TO BE DELT WITH. I WOULD NOT TOUCH A LENNOX UNIT SO UNSURE OF THE COST. AND IF NO TRANSITIONS NEEDED TO BE MADE I THINK IT IS HIGH, IF AS SIMPLE AS YOU SAY I THINK ABOUT $400.00 TOO MUCH!
