| Jan 5, 2017 at 2:23 | comment | added | gregmac | And why are you running the fan constantly anyway? I have mine set to run a minimum of 10 mins per hour (so basically the thermostat will run it if it otherwise hasn't run while heating/cooling), but my house has large south-facing windows and there's a very noticeable temperature gradient from the north to south side -- running the fan helps minimize the difference. | |
| Jan 5, 2017 at 2:21 | comment | added | gregmac | How cold is the cold air coming out? Obviously while the furnace isn't on, you're not going to get heated air. Is the furnace in the crawlspace? What's the ambient temperature in there? When you say the crawlspace is 'conditioned' do you mean it's been insulated? Are the vents inside the insulation of the house? Eg: sometimes they are run through the attic, above the insulation, so they're constantly being cooled by the cold attic air. | |
