Customer Reviews for Broan-NuTone Flex Series 110 CFM Wall/Ceiling Installation Bathroom Exhaust Fan, ENERGY STAR*

Not as quiet as expected but works well. Easy to install.

Easy to install and incredibly quiet

The first thing you'll notice is that this fan is extremely quiet. The instructions are clear and the installation is easy. The fan components are modular, meaning that the electrical connections, fan motor and the exhaust port are separate components contained in the frame. Each module can be removed for service without disturbing the others. I installed this fan in the ceiling of my shed to exhaust the hot air and humidity that occurs in Florida weather. The installation was a bit different in a shed versus a bathroom, but it wasn't difficult (see photos). It is Energy Star rated. I have it connected to a thermostatically controlled 110 VAC outlet so it uses very little electricity.

Most builder-installed fans are cheap and often undersized. Retrofitting a bathroom fan on the first floor of a two-story home can be a challenge. The Invent fans solve the problems for the most part. Usually, the toughest part is getting the old fan out so check out how it is secured before a DIY undertaking. Also, since these fans tend to be bigger than the old fans, make sure you have adequate clearance to the wall from the ceiling/floor joist where the fan is mounted. Be sure to include the clearance for the overhang of the fan grill. I have installed five of these fans now on my way to replacing all of them in our home. The ability to pull the (flex) duct through the housing with the fan motor removed is a real plus. Having both a top and side location for inserting wiring is also a nice extra. These fans move a lot of air. One issue I have not figured out how to resolve is how to replace all the old 3 inch duct and replace it with 4 inch duct in a first-floor/two story application. While this fan will still move more air than the old builder grade fan it means that it will not make it to rated capacity and the noise level is a little higher than advertised because of the backpressure even with a smooth 3 in. to 4 in. transition piece. Most homeowners and installers will notice a huge difference in quality between this fan and any "builder-grade" basic bathroom fan.

I had an electrician install the exhaust fan and no problems. I ordered this unit because it happened to fit the opening of the existing fan. I gave three stars because I am a little disappointed with the air it pulls.

It does a better job to remove moisture from the bathroom than my old fan. Unfortunately, It is louder than expected from 1.0 sone. I wish that I read some of the reviews before hands.

I was sent a Flex instead of an InVent Series. 2nd time it happens, defeats purpose of ordering On-line

The dimensions of the fan listed online do not match the actual fan. This was cross-referenced with an older Broan-Nutone fan but it’s incorrect.

Noisier than its noise rating suggests.

Very easy to install. Read all of the reviews for assistance.

The unit is well made, and as advertised. It is reasonably quiet given the CFM rating of 110. It is much quieter than the unit it replaced. If you are not handy you will need professional installation.

Great product all around

Is is so loud; I will be returning.

Great air flow and quiet which met our key objectives.

I bought this fan recently and it's already making lots of noise

Easy install and vast improvement in air flow. Much quieter than original unit

A quiet and efficient fan with easy old work installation. As most old fans have a 3 » vent, a reducer from the fan’s 4 » exhaust would be helpful

Nice fan. Easy to install. Quiet.

Price was reasonable and it is very quiet. It was a Good choice.

powerful and quiet. Better than my old bathroom fan that came with the property we had originally bought. Highly recommend.

They are not yet installed. I will give a fair review when complete. A contractor will start the project within a few weeks. Project should be complete within 8 weeks.

This is the most horrible fan ever, this is loud like more than 3 snores. Also it does not mention Broan on it. I feel like cheated by Home Depot.

Needed a simple and straight forward fan for our cottage. Performa as advertised. Good purchase

Exactly what I wanted and needed. Simple installation. Quiet, so quiet.
