Let me state right off the bat that this question is perhaps one of the most confusing for most people who are in the market for a new range hood.
It’s so easy to get drawn to all those big, beautiful range hoods lining the aisles in home improvement centers. Maybe one of those powerful, professional grade range hoods is exactly what you need. If you’ve opted for a large, industrial-sized stove, then you will most definitely require a large range hood.
Here’s what Range Hoods Inc suggests on the question of whether you need “make up” air or not with your new range hood:
When a range hood operates, it draws air from inside the house to the outside and creates or contributes to a slight vacuum in the house. The resulting negative pressure can be serious. If the negative pressure is strong enough, it can cause the furnace and other fuel-burning appliances to back-draft dangerous gases, such as CO, into the home. All exhaust fans, including clothes dryers, must have an adequate supply of air. The air needed for this purpose is called makeup air.
Although make up systems are not mandatory in all regions, some regions have created legislation to ensure make up air systems are installed, and it is important for homeowners to consult with local building codes. The installation of a ducted range hood allows air to be changed efficiently, which improves the quality of the environment in which you live.
Even if a makeup air system is not required or mandatory in a specific application, simply opening a window to the exterior can effectively assist in this process. This is something to consider in many of today air tight homes. Please check with your building inspector to determine whether or not you need a makeup air unit.
