Kitchen vents are easily overlooked and can be a serious health issue. Birds, which carry diseases and parasites, nest in these  vents, causing damage and unsanitary conditions. Once the kitchen vent gets blocked with a bird nest, there is a back-drafting of carbon dioxide gas, humidity and parasites onto your kitchen stove top. This could cause the kitchen vent fan motor to overheat, resulting in the destruction of the element. We strongly suggest the installation of animal guards to prevent this from happening to you. We call this our clean and screen method.
