The Dos and Don’ts of Installing Kitchen Exhaust Fans

If you enjoy cooking, a kitchen smoke extractor or exhaust fan is necessary. A kitchen exhaust fan often referred to as a hood fan or range hood, is required to eliminate the oil, smoke, and odors released into the air when cooking in your oven or on your stovetop.

You must comprehend the two distinct sorts of kitchen exhaust fans and their advantages before we can discuss installation:

Ducted Kitchen Exhaust Fans

A ducted kitchen exhaust fan circulates air from your kitchen outside after drawing it through the duct. This exhaust fan has fewer possibilities for placement because it needs ducting and pipe to extend from your kitchen to the outside of your house.

Compared to the ductless exhaust fans, ducted discharge the gathered air outside rather than just filtering or recycling it, which allows them to remove moisture from humidity and cooking steam.

Based on your level of competence, you can either hire professionals or undertake the installation yourself for ducted fans.

Non-Ducted Kitchen Exhaust Fans

Air from your kitchen is drawn into a ductless exhaust fan and passed through a charcoal or carbon filter, which eliminates odors and smoke before cycling the air back into the room, as opposed to filtering air from the outside of the house. Since they may be installed almost anywhere, ductless fans are a little more adaptable.

Filters for ductless exhaust fans must be cleaned or replaced every year. The ductless fan does not remove moisture, which means your kitchen might still become fairly humid. They can be a little noisier because they use more power than a ductless fan.

An Exhaust Fan Ductless Installation Guide

Since ducts or plumbing are unnecessary, installing a ductless range fan is not too difficult. However, if there is not one already, you’ll need to hire an electrician to install one because it needs its own electrical outlet. Once done, proceed as follows:

  • The wall’s center should be located above the stove.
  • Verify the dimensions of your new range hood to ensure you have the space required for installation.
  • Pay attention to the installation guidelines on your new hood fan. You’ll need to utilize a stud finder to secure the hood fan to the studs.

How to Install an Exhaust Fan with Ducts

A ducted range hood requires a little extra work to install. Before attempting to install the ductwork yourself, we strongly advise consulting with an expert at Aire Serv. If you haven’t previously, take these actions:

  • Determine how much pipe you’ll need to pass through your wall and out the other side.
  • To determine if you need to extend the pipe above the range hood or if it will go right behind it, check the directions on your new hood fan.
  • The hood range fan should be mounted 24 to 30 inches above your kitchen range. Cut into the drywall with a saw or drill using the template included with your fan.
  • Cut a vent in your outside wall using the outline of your pipe as a guide.
  • Place the vent cap on the outer wall and caulk it.
  • Install your new range hood once the electricity has been turned off. Follow the guidelines in the provided instructions.
  • Aluminum duct tape is used to join the required pipes together.
  • Restart the power and check out your new exhaust fan.
  • You can contact an expert about the installation if you need professional help.
