Central Air Fan Question

I just got Lenox Central Air system installed.
I had a question about the fan setting.
When would I leave the fan always on and when would I leave the fan to only go on when the compressor goes on? When might be a good time to leave the fan on even if I don't want to run the A/C?
How much electricity does the fan only use in comparison to the compressor and fan running together?
Thanks! David

Cost to run it depends on the size!! As far as running it continuously there is no need to unless your are trying to over come balancing problems in the home. I run ours because the lower level gets too COLD other wise. That said I run the fan continuously on my furnace/AC about 8 hours a day during the week, about 12 hours a day on the weekends. Adds about $20 to my bill at $0.06 a KW. Greg

If you have anyone in the house with allergies and a quality air filtration system, you could/should run the fan in the 'on' position. The filter doesn't do much good if there isn't any air going across it. The cost is minimal. Yes, this can make the house feel cooler because the moving air can cause drafts.
During the winter, I'll light the wood stove and get it cooking enough to heat the entire house. I do this by turning on the furnace blower and circulating the air.

How much it costs to run depends on the size of the unit figure 4 to 600watts at, .125kwh it costs apx 70.00 with 600w 24 x 7 . I have the smallest lennox, it pulls 420 watt, but the dc motor units take apx 1/3 the power

I have the 36,000 BTU unit. How can I tell how much electricity it uses with compressor + fan or just fan only?
I guess I understand that maybe I'd want the fan always on if I want to move some air around or if it's real humid or something like that. Otherwise fan on auto would be best I suppose.
Thanks.

That's a good one!! :-)

outside
so
Where in the fuck did you come up with these figures?? Small GE motor....1/4 hp @ 115v, 4.2a = 483 watts Large GE motor....3/4 hp @ 115v, 10.3 = 1184.5 watts
Now for a condensing unit.......small 1 1/2 ton unit new scroll compressor........2125 watts Now then a 5 ton unit...........6380 watts!!

As you can see your figures are waaaayyyy off!! Don't put shit on the web that you can't back-up.............. ..............for you will look bad when FACTS are presented! :-)
