General garage exhaust fan information  

Uncomfortably hot temperature and excessive humidity can be regulated by means of an effective ventilation system such as a fan. Garage exhaust fans are also designed to make sure that toxic fumes and dangerous gases get drawn out of the building.

This type of fans might slightly differ from those which are intended to be used in other parts of the house. Ideally, an exhaust fan that is designated to operate in a garage should be relatively big and tough enough to create a lot of wind power. Large fans are especially needed in the garages that are meant for parking of several cars. Also, those buildings that face west or south will benefit from the improvement of air circulation due to their predisposition to the increase of the air temperature. Mechanical parts of the car get heated while driving and after the vehicle is placed in a garage, metal continues radiating heat. This may cause problems to car owners particularly during hot summer months.  

If you consider installing an exhaust fan in your garage, look through several options carefully since if you happen to buy any badly designed or built product, it will perform poorly. This may be hazardous so planning air circulation with the right ventilation unit for your garage is important, which is why in this article we are going to help you choose the best garage exhaust fan.

How does an exhaust fan work?

Exhaust fans work by sucking humid or hot air from a building and replacing it with fresh air from the outside. The fan is designed in such a way that when the motor places the angled blades into the rotation, they collect stationary air and force it to be evacuated. Following the similar principle, fresh air from the outside environment gets sucked in into the building.

Exhaust fan VS air conditioner

Air quality can make a lot of difference in various premises, be it a residential home, warehouse, shop, greenhouse or a garage. Depending on the type of building and specific works that are carried out in the location, different types of ventilation and temperature regulation are required.

If you want to have fresh air and decrease the inside temperature to the outside level, it’s better to use exhaust fans.

In case your aim is to decrease the air temperature to the degree that is significantly lower than the degree outdoors, air conditioning systems might be more suitable for your building.

Bear in mind that installation costs, maintenance expenditures and energy bills of the air-conditioning system will be much higher when compared to an exhaust fan.

How much a garage exhaust fan costs

Typically, the cost of a garage exhaust fans ranges between $40 and $270 depending on the model, its capacity, and size. More complex vent types will cost more and will require a professional installation at an accordingly higher price.
