The Complete Guide to Commercial Exhaust Fan Installation

If yours is a business that revolves around cooking, you surely need a reliable exhaust fan for your kitchen. Also termed as the range hood or hood fan, the kitchen’s exhaust fan is a critical element that helps remove smoke, grease, & fumes that can be a part of the air. Given the fact that your exhaust does such an important job, regularly scheduled commercial exhaust fan service is a must.

Before we decode the dos & don’ts of the commercial exhaust fan installation techniques, you need to know about the types of exhaust fans.

Types of Kitchen Exhaust Fans

  • Ducted Kitchen Exhaust Fans:

This particular variant of the kitchen exhaust draws in air from the kitchen with the use of a duct & releases the same outside. The ducted variant of commercial kitchen exhaust requires the use of ductwork and pipes all through the kitchen going outside the home. This can lead to limited location feasibilities. If you are planning an installation of ducted kitchen exhaust fans, you can opt for affordable commercial exhaust fan service.

Given the fact that they happen to release captured air from inside the kitchen to outside, the ducted variant of exhaust fans can help remove the moisture present inside. As compared to their ductless variants, the ducted ones help remove the excess moisture coming from cooking in the kitchen.

Ducted fans obviously require the keen eye of a trusted installation professional for commercial exhaust fan service.

  • Ductless Kitchen Exhaust Fans:

As opposed to filtering the air present inside the room to the outside, your ductless exhaust fans help draw the kitchen air via a charcoal or carbon filter. This helps clean the air from smoke particulates or odors while cycling the same back to the kitchen. Ductless fans tend to be versatile in nature as they can easily be installed in a place you like them to.

The ductless variants require regular commercial exhaust fan service on an annual basis. The filters within these exhaust fans need to be replaced or cleaned in time. The only drawback of using such ductless exhaust fans is the fact that they fail to remove the moisture. So, your commercial kitchen might still be quite humid. Plus, they also need a higher amount of energy to operate as opposed to ducted fans. This makes them slightly noisier as well.

How can you install a ductless commercial kitchen exhaust fan?

A ductless variant of kitchen exhausts is relatively easy when it comes to installation as they do not require piping or ductwork. Plus, it requires its very own outlet to avoid any kind of electrical mishaps or overload. So, if you don’t already have a different electrical outlet in place, you might have to install one. You can take the help of a reliable technician for commercial exhaust fan service. After you are done installing the same, you need to follow all these steps:

  • Locate the center of the wall which falls right above the cooking range
  • Now, check the measurements of the new hood range. Make sure the kitchen has all the space it needs for the installation
  • After this, follow all the installation instructions that come with the hood fan to be installed. You have to use the stud finder. This will allow the hood fan to be anchored with the studs

How can you install a ducted commercial kitchen exhaust fan?

Installing the ducted variant of range hoods involve a bit more knowledge of the system. Unless done by a professional for commercial exhaust fan service, the ducted commercial exhaust installation process can be quite a chore. In general, the ducted commercial exhaust fan installation process involves:

  • Measuring the overall length of the pipe that is needed for extension through the wall to its exterior
  • Now, check all the instructions written on the new fan hood. You have to extend this piping above your range hood
  • After this, measure about 24-30 inches right above the kitchen range to allow the placement of hood range fans. With the use of the template that is available with the fan, you need to cut through the drywall with use of a drill or saw
  • With the use of the pipe as the outline, you need to cut a vent in and through to the outside wall
  • Now, caulk your vent cap & place the same on an exterior wall
  • You have to turn off the power before mounting the range hood. You can also follow the instructions included with the guide
  • Connect all the critical pipes with the help of an aluminum-based duct tape
  • Finally, turn the power back on & test the exhaust fan

All these steps might seem a bit overwhelming, especially if you have zero ideas about the installation process or the product. In such cases, you need to opt for professional commercial exhaust fan service.

Dos and Don’ts of Commercial Kitchen Exhaust Installation


Never try to handle the commercial kitchen exhaust installation all on your own. Try to correctly install the parts such as electrical fans, screws, ductwork, and so on could be a hectic and critical task. Failure to install things properly might lead to a complete system failure. To install the parts in a perfect way, you need to seek help for commercial exhaust fan service.


Make sure you teach the employees all the signs that help recognize any failure in the components. This will help with the immediate addressing of the concerned issue. Plus, you can ensure that any mistake of your employee doesn’t lead to service failure.


Do not already assume that all the service providers know what they do. Not every professional technician can provide service in your desirable model. They may be a pro at installing other models; their panache might not be in the model that you have in your house. So, make sure you hunt for a service provider that understands everything about the exhaust fan model you have.


Make sure the system is cleaned on a regular basis after installation. Given the fact that an exhaust system is such a critical part of your daily kitchen development, you have to clean it a minimum of once per year.


Do not put off the maintenance cycle for your exhaust system. With time, grease and oil build-up can lead to potential fire hazards. This is why it should be eliminated in an appropriate manner.


When talking about proper commercial exhaust fan service, the installation process is as critical as maintenance. Unless your exhaust system works properly, you might not have a healthy kitchen to go to. If you happen to suspect that your kitchen is getting kind of steamy and hard to breathe or see, you need to quickly replace your existing exhaust system or install one that can handle all those particulates in the air. However, make sure you have the installation process done by a professional commercial exhaust fan service.
