Basement intake fans effecting home HVAC?

I was told that pulling cool basement air to cool room/reflectors can make my furnace/ac unit to run a whole lot.Any truth to that??. I was planning on using 2 700 cfm fans to pull cool air to cool reflectors,and maybe 2 350 cfm fans for intake.The grow room is in the basement,split in half.I was told that with that many intake cfm fans it might mess with carbon monoxide of the house also.

How is this possible?I was under the assumption to use cool basement air for your grow room...

yes it alters the house ........instead of having a static pressure where the heat transfer is at a steady rate u are now pulling in air from the outside tho the cracks to even out pressure change

this is from u dumping the air outside from the grow rooms ..........so it will alter all know thought on drafts air current movements and heating bills/cooling cost

if the house is really well sealed and built the path of least energy would be the HAVC systems ...a older house u should be fine

Your furnace/ac is controlled by your thermostat. Obviously lol. So it will have an effect on your house, cooling it down, but wont make your furnace insufficiently run unless your thermostat is close by. My advice. Shut off the thermostat when possible. Ac is not an issue. It will kick on when its too warm anyways. But heat will come on when your thermostat location is triggered by the temperature setting. So either.

Keep thermostat much lower than usual, 60-65, if its close to op.

Or

Shut then furnace off when possible.

Better yet!

Move thermostat as far away as possible!

Its hard to say without knowing where you live what the weathers like outside. But keep in mind. You can set thermostat to run on a timer! As well as your cooling intake system!

Further assessment would require geographical location and relative distance from op to thermo!

I was wondering about this too...

I have a tent in my basement. I pull air from the basement and exhaust it outside. I was having some repairs done in my kitchen and as soon as we busted through the ceiling drywall there was a massive draft coming in, I'm assuming my exhaust fan is causing this.

So, if I'm pulling air out of my house faster than its being replaced then my house is under negative pressure. Will this cause my heating bill to be higher than normal?

I live in the great lakes area ,cold in the winter &does get humid in the summer.I am using half the basement for grow (10x20).It's a quad house, thermostat is on the first floor above the grow room.

Is it possible that those fans can start sucking air from holes thru the first floor where the doors/heat vents are located?

I guess my other option would be to cool the lights thru duct pulling air from basement window which I 'd rather not,because of different temps cooling lights,not including how hot it gets in the summer which means pulling hot air to cool hot reflectors.

Edit:I have a gas furnace and water heater that are within ten feet of my grow room.
