Professional Vs. DIY

Unless you are extremely handy, you will probably need to hire an electrician in order to install your bathroom fan. The price of labor for an electrician differs from city-to-city, however, the average electrician charges anywhere from $50 to $100 per hour. Typically, it takes two to four hours to install a new fan. This also depends on how intense the job is.

If you are just replacing an old fan and there is already wiring installed, the job will not take long at all. If you are adding a fan to a bathroom that previously did not have a fan, you will need to have new wiring installed, which can be a lengthy process and will cost you more money. 

Pre-Existing Location Vs. New Location

When you are installing a new fan to a bathroom that previously did not have a fan, you will have to expect to spend a much larger sum of money. In this situation, you will have to install ductwork. The cost of this will depend on the size of your home.

If you have a smaller home, you will probably only pay a couple of hundred dollars. If you have a larger home, you could pay over $4,000 to install ductwork. 

Placement

In addition, the placement of the installation also plays a role in how much it will cost. If you choose to install your new fan through the roof, it will cost $2 to $3 per foot. If you choose to install your fan through the wall, it will typically cost around $50. 

Now that you have a basic understanding of how much it might cost you to install your new bathroom fan, you might have a few additional questions. Keep reading to find out more information on the installation of a new bathroom fan.

In short, theoretically, someone could install their own bathroom fan. However, if you do not have an understanding of electrical work and maintenance, you should hire someone to do it for you.

If you improperly install a bathroom fan, you run major risks of starting an electrical fire. Safety should always come first, so if you are planning to do this project and do not have an understanding of electricity, hire someone to help you out! 

Is It Difficult To Replace A Bathroom Fan?

If you are just planning to replace an old bathroom fan with a newer fan, the job will be much simpler than it would be if you were installing a totally new system to your bathroom. The electricity is already wired to the old fan. You will only need to remove the old fan and install the new one. A new project would require the installation of the electricity as well. Although this project may sound simple, you will still want to hire a professional for help. 

How Long Does A Bathroom Fan Last?

The average bathroom fan will last around 10 years, however, there are things that you can do in order to extend the life of it. Running your bathroom fan regularly can help to increase its lifespan. If you never turn it on, the motor will slow down sooner, and the fan will not last as long as it would if you run it regularly.

In addition, routine cleaning will help keep your fan in top-notch shape. To clean your fan, you should first wipe it down with a soft dust cloth to remove any loose dirt and dust. You should then take a damp wet cloth and wipe down the vent again. You should also take apart the fan and clean the inside. Be careful not to use any chemicals on this for cleaning. You should only use warm water, and for excessive grime, vinegar.

By removing the gunk and grime that grows on your bathroom fan, you are helping to increase the lifespan of it. You should clean your bathroom fan at least once a year. Clean it more if you notice an obvious amount of dirt or dust growing on it. 

How Do You Know When To Replace A Bathroom Fan?

There are a few different signs that may tell you it is time to replace your bathroom fan: 

Noise

Most fans make a bit of noise when you run them, however, if you notice that the noise of your fan has changed, it is probably time for a replacement. Your fan should not be overly loud. This is a sign that the motor is about to die. 

Foul Smells

If your bathroom fan does not filter pesky smells, then it probably is not working the way it should be. Your fan should help to filter the normal stinky smells of a bathroom. If these smells are persistent and constant, replace your bathroom fan. 

Mold

If your bathroom is growing mold at an unusually quick rate, it is probably because your bathroom fan is not working properly. Most people do not realize that bathroom fans are not only to keep to room smelling nice but also to decrease the moisture and humidity, ensuring that mold does not grow inside your bathroom. If you are noticing an increase in mold, it is time to replace your bathroom fan. 

Lifespan

As a rule of thumb, you should replace your bathroom fan every ten years. These models do age with time and the longer you own one, the less likely it is to be effective. 

In Closing

In the end, it is clear that there are many different components that go into replacing or installing a bathroom fan. Our biggest advice to you is to hire an electrician to ensure that you are doing the job safely. As mentioned, the cost of this job differs from situation-to-situation, so please take this information into consideration before you begin your job.
