  • 744SFL is rated 4.0 out of 5 by 11.
    Rated 5 out of 5 by from very nice features Installed this unit right in the shower in the basement with a drop plastic tile ceiling. I vented it straight out to the outside. It turned out very nice, kicks in when the humidity level gets up there and runs until the humidity has been exhausted, then turns off. I also used the Broan 2 way switch that allows you to run the unit bypassing the auto feature. The light bulbs you can't find at the big box stores but you can find them on the web...no big deal.

    Rated 2 out of 5 by from Replacement Lamp Finding it almost impossible to find a replacement lamp for this fan. Beats me that it could not be designed for a standard threaded base bulb. They need to come up with a retrofit kit to change the bulb base.

    Rated 5 out of 5 by from Broan 744SFL I am pleased with this humidifier. One cannot know it is a dehumidifier as is round as my other lights, it is very quiet, and does the job liked a champ.

    Rated 1 out of 5 by from Bad Quality After a few years of use there are rust inside that can been seen and some parts are broken off due to rust. Fan and recess light are on the same switch. Would not recommend this product in its current specifications, perhaps coating all of the metal parts with paint of some type of resin coating would help to improve on the product longivity. Two-in-one (fan + recess light) is an awesome design for tight space though.

    Rated 5 out of 5 by from Great unit for small bathroom! My wife and I were shopping for a bathroom fan that looks good, is quiet, and keeps the bathroom dry after long showers. My bathroom requires a fan rated for 64 CFM minimum. We selected the Broan 744 with a rating of 70 CFM. The fan is quiet and the recessed installation appeals to us. Shortly after installing the unit, however, I noticed that long showers resulted in moisture on the ceiling. I went up the attic to inspect the installation and re-taped the exhaust duct to the unit for a good seal, and also re-positioned the attic insulation flat/against the top of the ceiling sheet rock to minimize condensation due to the cold air in the unheated attic and the warm bathroom. This helped alleviate moisture on the bathroom ceiling after showers. My only recommendation to readers is when determining minimum CFM required, note whether your installation is ideal per Broan instructions. If not, consider purchasing a fan that exceeds the minimum required CFM. For example, if you use a corregated duct in lieu of sheet metal, or have an additional 90 degree turn or elbow, don't hesitate to select a fan with a higher CFM. The Broan 744 has been installed for nine months and is meeting my family's needs and expectations.

    Rated 5 out of 5 by from Wonderful Fan - So Quiet I sometimes think its off! This fan is amazing. Not only does it look much better than those ugly and huge grill type fans, but its so quiet. I seriously have to stop sometimes and stand still to hear it. The humidistat feature is fantastic as well as it comes on automatically and leaves me with worries about moisture. I would highly recommend this fan. I've had mine for a full year now and have no regrets. I'm an architect by the way, and I now use this fan on my projects if I can.

    Rated 1 out of 5 by from Dont waste the money I purchased a broan 744sfl for a bathroom remodel. After installation, the light did not come on. I replaced the bulb and it still didnt come on. I called Broan support and they informed me that there is a design revision since they had issues with the light on the initial design. The revision includes the bulb, light module and humidity sensing module. When i installed the revision, the fan would not turn off. After talking with Broan support again, I got a replacement revision module. I installed that and the fan appeared to work correctly until we got a more humid day at which point the fan cycles on and off all day. I set the humidity sensing calibration to its highest setting and the fan still cycles at 50% humidity. At this point, I'm ready to either wire the fan to an on/off switch or just buy a non-sensing fan. This appears to be a product with on-going design issues. Do not waste your money.

  • Can a LED bulb be used with the 744SFL?

    Asked by: belle
    Thank you for your question on the model 744SFL humidity sensing exhaust fan/fluorescent light. The 744SFL is designed to use an R30, BR30 or PAR30 shaped 16 watt maximum compact fluorescent lamp with GU24 base. We cannot suggest or recommend using any other bulbs with this unit.

    How do I turn the fan off completely?

    I know that I want to have a separate switch for the light. But how I understand from the wiring diagram, if you use the 68W switch, I can only switch from manual (always on) to auto (humidity sensing). I would like to be able to turn the fan off completely if I were to take a really hot bath and I don't want it turning on at that time.
    Asked by: thebluebungalow
    Thank you for your question on the model 744SFL humidity sensing exhaust fan/light. For your specific application, you would want to use three switches, one to power the humidity sensor, one for the fan override and one for the light. If you only have two switches and the associated wiring, you would want to use wiring option number one. Please contact the Technical Service Department at 800-637-1453 if you need further assistance.

    What size R/O should be cut for the light baffle?

    It looks like the baffle is 7 3/8 inch in diameter. Should the rough opening be a standard 6 1/4 for a five inch recessed can, or something different? Thank you.
    Asked by: MIke
    The diameter of the hole is 6 1/4". However, you will need to install this fan from the attic.

    can a waterproof lens be installed over the light, as the second light in my shower has one

    Asked by: mark
    Thank you for your question on the model 744SFL humidity sensing exhaust fan/fluorescent light. There is no option for a lens to be installed over the bulb in the 744SFL. The grille also needs to stay open for the humidity sensor to work.
