Does a furnace room need ventilation? Most new building codes require that spaces that house gas-fired appliances such as water heaters and furnaces have an outside ventilation source to provide combustion air. Electric Furnaces or water heaters do not need ventilation to support combustion.
Is it OK to run furnace without a fan?
In fact, there’s no need to worry about the fan wearing out or breaking down because it’s designed to run continuously, and there’s an array of benefits connected to this. Here are some of them: Better circulation of heated and cooled air.
Does furnace need fresh air intake?

Why is my furnace room so hot?
A furnace can suddenly overheat for a variety of reasons, but it is typically due to a blockage within the ductwork of the furnace. For example, a filter that is completely blocked with debris and dust can stop air from freely flowing out of the furnace.
What should you not put in a furnace room?
Never leave any combustibles in the furnace room. Don’t store anything near your furnace that’s combustible at low flash points – like gasoline, paint and paint thinners. Always keep the area free of dust and debris – vacuum and clean around your furnace and water heater tank to prevent dust buildup.
Does furnace fan pull air from outside?
Since high efficiency furnaces draw air directly from outside, the furnace itself does not require a fresh air intake in order to replace inside air that otherwise would have been drawn from the room the furnace is located in.
Should I keep my furnace fan on or auto?
“auto” is the best setting for your furnace fan in the winter. It will aid in saving energy and money while also working to keep your home at an optimal temperature. However, for summer, “on” is the best setting for your furnace fan.
Does a furnace room need a louvered door?
A furnace room needs a louvered vented door. The louvered door allows venting to get combustion air into the furnace room. When the furnace pushes air into the home, it needs an equal amount of air to go back into the furnace room to work efficiently.
Does a furnace need a cold air return?
No furnace can adequately operate without sufficient return air supply. We can think of a furnace as lungs. It ‘breaths out’ hot and it ‘inhales’ cold air. Air return vents are necessary for the ‘inhale’ process.
Is it safe to have furnace in bedroom?
It’s not recommended to have a furnace in your bedroom closet due to the toxic fumes that a furnace emits. Keep the furnace as far away from the air you breathe as possible. Furnaces are built to not only heat bedrooms but entire houses.

What kind of door do I need for a furnace room?
The kind of door that should be in a furnace room depends on the airflow quality in the room. If you don’t have at least two vents bringing fresh air into the boiler, then you should install a louvered door. Otherwise, a door made of gypsum is generally acceptable.
How much airflow does a furnace need?
A direct-vent furnace requires about 50 cubic feet of air for every 1000 BTUs of fuel input. The label or documentation with your furnace or water heater can tell you the BTU fuel input.
Can you close in a furnace room?
Unlike the requirements for boilers, your furnace room should never be fully enclosed without proper ventilation. Enclosed spaces increase your risk of exposure to flue gas, which includes toxins like carbon monoxide.
How much room does a furnace breathe?
As a general recommendation, your heater should be 30 inches away from furnace room walls on all sides.
Where does your furnace get air from?
Typically a furnace will suck air from inside of the house (probably the vent behind your couch), pass it over the heat exchanger, and blow the now hot air out of the vents in your rooms.
Does running furnace fan clean air?
By running the furnace fan all the time, you are also running air through your furnace filter constantly. If you have an efficient filter and a UV light, you are constantly filtering and cleaning the air. This results in healthier indoor air quality for your family and less dust on your furniture.
How do you put fresh air in a tight house?
Supply Ventilation: Supply ventilation systems use a fan to pressurize your home, forcing outside air into the building and stale air to leak out through holes in the building envelope (bathroom fans, kitchens fans, etc.)

Fresh Air Intake: If there’s a screen, it’s an intake. This is where the cool fresh air makes it’s way back to your HVAC equipment. You can test this by turning on the furnace and feeling the suction as it draws air in. Exhausts: If the vent has a flap, it’s an exhaust.
What happens if there is not enough return air?
If there is not enough return air available, your HVAC system will not heat or cool properly. They must be properly sized — Return air ducts must be large enough to carry a sufficient amount of expended air back to your furnace, air conditioner, or heat pump.
