FAQ:

Q: Is it bad to cover a furnace vent?

A: You could mess with the air flow. Just because you cover the vent, it doesn’t mean your HVAC system knows that. It will keep pushing air to those vents, and if they’re closed, you could cause a buildup of air pressure and insufficient airflow which could damage your system. You could damage the heat exchanger.

Q: Does furnace room need ventilation?

A: There are several good reasons that a furnace room should have ventilation. Notwithstanding the local building codes, any gas-fired appliance needs a source of combustion air to burn freely and effectively. We’ll help you understand the heating process mechanics and how those mechanics can affect your home and safety.

Q: Is house vent fan cheaper than air conditioner?

A: The operating cost of a whole house fan is much cheaper than running air conditioners. Home improvement experts agree that a whole house fan can be run at one-tenth the operating cost of air conditioning, you may be able to reduce your energy costs by 80 percent by installing an energy efficient whole house fan.

Q: Can you put furniture over floor vents?

A: Subsequently, question is, can you put furniture over floor vents? It’s unlikely but not impossible that blocking a heating vent and causing the furnace apparatus to overheat could cause a fire. Put the furniture over the vent in summertime, and you decrease the overall air flow from a central air-conditioning system.
