Jessica Posted January 7, 2017 Report Share Posted January 7, 2017 So there is a debate about running your furnace in auto or on. my house is older, storm windows and wooden style windows and wood siding. its a little bit drafty but not bad. we have central heat and air. my furnace is in the basement and the temp there stays fairly stable. Im curious if the cost of running the fan in on and just using the basement air to help regulate the temp would be better than trying to keep up with the normal drafty-ness of an older home? winter here has been pretty mild but its like 0°f right now.

ShadeTreeMechanic Posted January 7, 2017 Report Share Posted January 7, 2017 It might help a little. I used to turn the blower on without the furnace when we would burn the wood stove and it seemed to help even out the areas of the house a little. 91 C350 Centurion conversion ( Four Door One Ton Bronco) 250A Alternator (Second Alternator Coming Soon) G65 AGM Up Front / Two G31 AGM in Back Pioneer 80PRS CT Sounds AT125.2 / CT Sounds 6.5 Strato Pro component Front Stage CT Sounds AT125.2 / Lanzar Pro 8" coax w/compression horn tweeter Rear Fill FSD 5000D 1/2 ohm (SoundQubed 7k Coming Soon) Two HDS315 Four Qubes Each 34hz (Two HDC3.118 and New Box Coming Soon) Link to comment Share on other sites More sharing options...
Broke_Audio_Addict Posted January 7, 2017 Report Share Posted January 7, 2017 Unless your cold air return is in your basement leaving the fan set to on isn't going to help circulate the basement air throughout your house That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.

audiofanaticz Posted January 7, 2017 Report Share Posted January 7, 2017 No difference. What Broke means is your furnace puts hot air throughout your house, in return it sucks out cold(ish) air from cold air return vents through out your house. Those vents are typically on the opposite side of the room as your heat register(s) or one on each end of your house. So when you run your blower motor on all the time without the heat, it is just taking the heat from your warm rooms and sucking it down to the furnace and back out the vents. Your furnace filter is between your cold air return ducting and your furnace. The hot air coming out of the furnace is not filtered, only the cold air coming into it. But since the cold air returns are often from your first floor, you will not be getting any of the warmer basement temperatures by leaving it running. If your house is drafty, it may make it more drafty leaving it on. Link to comment Share on other sites More sharing options...
audiofanaticz Posted January 7, 2017 Report Share Posted January 7, 2017 Plus leaving it running will mean you will have to change filters a lot more often. Ideally you should do it every 3-6months, possibly sooner if you have a dusty home, or older duct work that are full of dust. Link to comment Share on other sites More sharing options...
Jessica Posted January 7, 2017 Author Report Share Posted January 7, 2017 @audiofanaticz oh, that makes sense. my cold air returns are upstairs near the ceiling.

audiofanaticz Posted January 7, 2017 Report Share Posted January 7, 2017 Odd to have cold air returns on the ceiling since hot air rises, they are normally lower. Though it doesnt matter to much if the air is warm or cold. The main point of the cold air return is to give the furnace an intake of air, otherwise the blower motor struggles if it is starving for air. Plus they help circulate the air in the home. Funny thing is I just fixed a furnace today. The limit switch kept tripping due to not enough air intake, the furnace was running hotter than it should due to the blower not being able to freely move enough air through the heating elements causing them to run hot and trip the switch after only a few minutes of run time. Similar to what happens if you cover up your intake on your vehicle, the motor starts to suffocate until it dies out. Link to comment Share on other sites More sharing options...

audiofanaticz Posted January 7, 2017 Report Share Posted January 7, 2017 running it all the time still may help even out hot/cold spots in the home though, but you could really get similar results with a ceiling fan or 2 on low spinning in reverse, and would most likely be less of a power consumption than the blower.
