Air intake/return on an oil furnace
 
1 Attachment(s)
Hello, I have a question about the air intake on an oil furnace.

There is a big vent on the lower area of the furnace and the inspector said this was the only intake. He said we should have intake ducts coming in from the second and first floor, or only first floor at a minimum...but not only coming in from the side vent on the furnace in the basement.

He mentioned we should have someone come in and quote us to have intake ducts. This would make the intake air warmer coming in from the first and second floor as opposed to using the basement air.

Also he said using the basement air as intake isn't good because he said the the furnace is polluting the basement air and pointed to the draft-regulator when saying this as if it was the exhaust. Which it isn't right? Exhaust is going up the old chimney..I think.

So I just want to confirm that I need to have someone install intake ducts to the first and second floors so we aren't using only the basement air intake on the unit.

Yes, it needs returns on the first or second floor. How is the upper floors returning the conditioned air already? Are you in the process of purchasing the home, or do you own the home? If purchasing, tell the sellers to fix. If it is a foreclosure, it is your dime to fix that problem and others.

Apparently there are no returns on the 2nd or 1st floor. Only intake/return is that vent on the side of the unit sucking the basement air.

We're in the process of buying it. From a few HVAC companies discusing over the phone, it will be $1500-$2500 to run a few returns from the first floor to the unit.

Trying to get someone to go in with me to take a look for an accurate estimate.

There are several things to consider.
one,that return looks way too small.
Second drawing all the air from the basement is most likely costing a lot more to heat the house.
Third the house is probably uncomfortable with swings in tempature.
Fourth because of the cheapness of the install you should probably have a manuel "D" done so you don't end up with future probablems.
Fifth,does this furnace have a filter?
good luck

Is the door between the basement and rest of the house louvered? Are there any registers in the floor of the first floor that just open to the basement?
