My best guess is that the blower is under the most strain during startup.
Continuous run doesn't start the motor, so you'd get more actual hours of
runtime if you just leave it on.

However, those hours of runtime will be condensed into fewer days, weeks,
months.

I'm sure there are some motor experts who will have facts, web pages, etc.
But such is my guess. I'd say leave the fan on if it makes you more
comfortable.

Just a question regarding the blower motor on my furnace. I just had the
evaporator AC coil replaced. I mentioned to him that even before it went
bad the home does not seem to stay cool for long. He told me to leave the
fan switch on the thermostat to on so that it blows 24/7

Well needless to say that makes a huge difference as the compressor isn't
needed as much.

My concern is will this shorten the life of the motor? And, is it ok to
leave the fan on 24/7 for 2, 3, 4, 5 days? My thinking is to leave it on
for whatever the duration of the heatwave. Correct?

Thanks...



I have a Trane AC/Furnace Its 3 years old now when I had it first installed
I had a cooling issue. The HVAC tech came out and suggested to me to
leave the fan on 24/7 I do that and closed down some of the vents so the
cool air goes up to the 2nd floor and have wall vents now have plastic
diverts to blow the air up. To make a long story short the tech also said
the newer furnaces blower motors are designed to run 24/7. Even when its
cooler out side when the ac is not on and windows open I still run the
blower
its like running fans low. I run my ac most of the time due to heath
reasons
my electric bill just is 25 to 30 more than usual.
