Air King BFQF70 Exhaust Fan with Light,4-Inch round

This is a nice fan. The plastic housing is one of the things that makes it quieter since sound doesn't resonate through plastic like it will with a metal housing. The bulb that it comes with is a 26W 2700K GU24 bulb. I prefer the daylight bulbs in a bathroom, so I purchased a  23 Watt - 100 W Equal - Full Spectrum 5000K - CFL Light Bulb - GU24 Base - Global Consumer Products 175  to replace the bulb that comes with it.I've installed several of these fans, and there are a couple of tricks that can be used to ease the installation. These tricks assume that you are replacing a fan and the wiring is already in place. My favorite way to remove the old fan is to use a reciprocating saw to cut the nails that are holding the old fan in place. Drive a screwdriver up between the joist and fan housing to give the blade just a little bit of room. Then, just stick the blade up and cut the nails. Rotate the fan and drop it down, remove the wire from the housing.1) The preferred method is easy enough, but it can still be a little hard to get the fan snapped in once it is in place. First, the hole needs to be cut at least 1/4" wider than the fan so that it can be tilted up and into place. Mount the bracket centered in the hole, and wire the fan before attempting to push the fan up and into place. Because of the discharge, it cannot be pushed straight up, but must be tilted to get it up into the hole, straightened in the hole, then pushed upward and snapped into place. If it won't go, cuss it. If it still won't go, get a bigger hammer. Or, you can use a putty knife to push the housing up and back so that it will snap into the bracket.2) If the first method will not work for you, then try this little gem. Make "keyholes" in the bracket. There are 4 holes in the top of the bracket, If you drill out the bottom hole with a 1/2" bit, you can then use a Dremel to cut a slot up to the top holes. This will allow you to screw the bracket to the joist but leave the screws just loose enough that you can slide the bracket up and off of the screws. Make sure you have the bracket perfectly centered. Clip the bracket on to the fan and make sure it is centered. Wire the fan and then slide the fan up through the hole, maneuvering the screws into the keyholes, and slide the fan down into place. Next, you need to secure the fan so that it will not slide up. To do this, drill a hole through the housing and the metal bracket and put a single screw into the joist. If you have the bracket properly centered, you can drill the hole through the housing and bracket before putting the fan up and wiring it This will keep the fan from moving upward off of the screws once a screw is placed through the lower hole and into the joist.I hope these tips will be helpful to the DIYers. Please mark this review as helpful to keep it toward the top so that others can see it more easily.UPDATE 3/27/2018: If you don't like being forced to use a GU24 base light bulb and would like to use a standard medium base screw-in bulb, then do a search on Amazon for the "JACKYLED GU24 to E26 E27" adapter and kiss that GU24 base light bulb goodbye.I'm still buying these fans and usually install about 8-10 of them per year. All of my customers love them because they are quiet!!!

Basckground you can skipWe wanted to replace our old and worn 50 cfm Broan 4 sones fan/light unit. This unit was installed in a slanted ceiling with NO attic access.Naturally we wanted to go fancy and install a fan/light/heater unit but when the unit arrived the electrician told us we needed to rewire to accomodate all the switches and connections and on top we'd need to upgrade the circuit from the existing 10amp to 20 amps.He then charged us a 75$ show fee and left even though he had recommended the fan.Anyways, we ton ed down our expectations and decided we wanted to just replace with something quieter, less obtrusive, more modern, more energy efficient that could also be installed easily without attic access.About this unitWell, this is probably your best bet when looking for as no-hassle retro fit with no attic access. The opening required was a quarter inch more than that of the existing small Broan unit and it came with one wide metal clamp that could easily be installed from below. with 4 screws into a ceiling beam or cross stud. The housing, once the duct is connected and the wires are connected then simply slides in with a satisfying click.I then was able to connect the VERY simple electric wires for the fan and light unit.The light and fan components then plug in.The other great thing about this retrofit is that it is very forgiving. The unit did not sit flush with the ceiling because my cross beam was way out of plumb but then i added the cap and screwed it on it pulled it fit against the ceiling.The whole ordeal took me, a novice with little electric experience other than understanding the basics, about 30 minutes.Also, this unit is very basic/modern. The light cap is almost as white as the housing trim and therefore the whole unit is not very visible until you switch it on and the bright light shines. Due to the the light cover not being transparent it has a clean look even when switched on since the bulb remains hidden.Also, it is as quiet as they promised on the box.We are very pleased with this unit as our bathroom no longer fogs up when taking that hot morning shower. Not even our glass shower doors fog up.PROS- Extremely simple retro-fit installation, even when no attic access.- Very forgiving design when it comes to out of plumb situations, slanted ceilings etc- Requires 10 amps dedicated but this is an energy star unit that requires minimal power and I did not use a dedicated circuit and have no issues.- simple wiring needs. Most homes will be able to install this unit whereas some of the newer units require expensive rewiring or over the top dedicated 20 amp circuit installs.- the unit is very quiet for this price-range. you can hear it but just a little and when the water is running you cannot hear it at all-it comes with a 100 watt equivalent bulb (13 watts) that is very bright. Nice they included that.- the light cap is not see through or semi see through so you don't see an ugly bulb, even when on.CONS- Haven't found any yet. Compared to the Broans and Panasonics and the aero Pure's this unit has superior specs and performance in the sub 60$ 70CFM, <2 sones fan/light units spectrum. Excellent choice, especially for retro fitting.
