One of my buyers was able to get a new furnace when the original (which had a 5 year old motor) unexpectedly gave up the ghost.At about $450  to $500 it is cheap piece of mind if you worry about future complaints or claims.

Motor City is earning and gaining global attention once again.

But it was a flip so we wanted to make sure it had a warranty & that required a lic HVAC guy.A year later in the middle of winter both the blower & inducer motor fail but lic HVAC guy was too busy so earliest was 3 days.

My plan:-Clean all the dust off the inside (very minimal if any)-Test amp draw on blower motor vs FLA-Test capacitorFurnace info:Gas furnace, 80% efficiency (the efficiency does not influence my decision)Manufacturer: International Comfort Products CorpModel# NTC6100GFA1Curious if anyone has any other recommendations? 

Your return air has no effect on the burner section of a furnace, every furnace has an induced motor for this.

Based on it being Lakefront, it’s most definitely more attractive and more marketable than not, albeit on a small “non motorized boat” lake.  

I currently work in the auto industry for Ford Motor Co.

Though, if the blower in your furnace is not a DC variable speed unit {i.e. an old single speed 75-100amp motor}, you should consider replacing the blower since it will be running year round and the blower tends to be the biggest energy consumer in older forced air systems.If the gas furnace is older (only 65 - 75% efficient vs 95% in a modern furnace), you could always replace it with a hybrid solution ... natural gas heat with an electric central air cooler.

But the damn motorized thing was so noisy I we stopped using it.
