Gas Furnace replacement? 15 years old
I have a Lennox Pulse 21V Furnace (C26-51FC-10 which i had installed about 15 years ago. a few years ago i replaced the motor (in the depths of a cold spell).
this morning i noticed that the inside temp was 58 when the setting was for 68 degrees. i checked the thermostat and it was set correctly. it is fairly new, it was replaced a couple of years ago.
i was told some time ago that a furnace reaches its replacement point at about 15 years. is this correct? i have put in a call to the technician to come on Monday to check the unit.
if i am to replace this furnace, i would appreciate your recommendations.
