Nothing is durable in our life. Sometimes, even the most stable things can fail. In the case of bathroom exhaust fans, it is not the only problem why you will need to replace them. There is a widespread problem when the fan is incorrectly installed into attics. This can cause moisture and mold. Instead of fighting, the fan will only enlarge them.
In this article, we will explain how to replace a bathroom exhaust fan without attic access. If you haven’t still chosen a new fan to replace the old one, you can find the best-suited option in our list of bathroom exhaust fans.
It is important to check the sizes of the previous fan before buying a new one. First of all, you should remove the fan cover by pulling on it at a slight angle. Now measure the exhaust fan housing. Also, measure the fan duct size. Usually, they are 3 or 4 inches. That means that if the size of a new and previous fan is different, you will need to buy a duct adapter. But because of it, the fan can work louder and less effectively.
Also, you will need to consider whether you want to change wall switches. New bathroom exhaust fans have a light, heater, or humidity sensors. If you want to control them by yourself, it is important to buy a new switch that will meet the requirements.
One more fact to pay attention to is actually the new exhaust fan. You should consider Cubic Feet Per Minute (CFM). It should be at least equal to the listed square footage in the bathroom. The next factor is noise level. The fan should be quiet and should not annoy you. It is better to look for energy-efficient fans. They reduce your energy bills by saving energy. You can find a list of exhaust fans and read how to choose them in our previous article. Now you are ready to replace an old fan.

There are tools that you may need in some cases but not necessary.
