Air King recommends that an LED light bulb be used in all of it's products. LED bulbs provide the most energy efficient solution and can be used in all products. LED bulbs are required for all ENERGY STAR® certified exhaust fans. Fluorescent bulbs as well as incandescent bulbs can be used but do not provide the energy efficiency of a LED bulb. If using an incandescent bulb, make sure to reference your specific model for the maximum wattage.
On most exhaust fans the model number is located on a sticker on the inside of the housing. You may need to remove the grill in order to see the model number.
MAKE SURE POWER IS SWITCHED OFF AT SERVICE PANEL BEFORE SERVICING THE UNIT. Clean your exhaust fan's grill with a mild detergent, such as dish washing liquid, and dry with a soft cloth. NEVER USE ANY ABRASIVE PADS OR SCOURING POWDERS. Completely dry before restoring power. NEVER IMMERSE ELECTRICAL PARTS IN WATER. The fan assembly can be vacuumed when build up (dirt, lint, etc.) accumulates over time.

Exhaust fans provide ventilation, helping to clear the room of steam and odors. Properly ventilating a bathroom helps deter the growth of mold and mildew by ventilating excess humidity from the room.
Although there are many factors that will determine what size exhaust fan you need, as a general rule, take the length times the width of your bathroom to come up with the square footage. Assuming the ceiling height is 8 feet, take the square footage and multiply it by 110% (or 1.1). This will give you the amount of ventilation needed for your bathroom. For instance a 10 foot by 10 foot bathroom with 8 foot ceilings would have a square footage of 100 sq. ft., take 100 times 110% to get 110. You would need an exhaust fan with 110 CFM to properly ventilate the bathroom. Higher ceiling heights will require additional CFM.
Cubic Feet per Minute. Unit of measure for how much air is exchanged in one minute of time. The higher the CFM the more "powerful" the exhaust fan is.
A sone is an internationally recognized unit of loudness. The sones translate laboratory decibel readings into numbers that correspond to the way people sense loudness. Double the sone is double the loudness. In everyday terms, one sone is equivalent to the sound of a quiet running refrigerator in a quiet kitchen. The lower the sone, the quieter the exhaust fan is.
Exhaust fans with a UL listing for installation over a tub or shower on a GFCI circuit can be installed over a tub or in a shower. This applies to most Air King exhaust fans and exhaust fans with light. Units that include any type of heating function to them are not able to be installed over a tub or shower. Check you specific product for more information.
YES. Confirm your unit's IC (insulation contact) rating. Most Air King exhaust fans, exhaust fans with light, and heater combination units are IC rated to R40. Check your your specific units rating along with the insulation rating covering the unit. This information can be found on the specification sheet available through this web site. Navigate to your specific model or use the search at the top of the page to find your product.
NO. Air King exhaust fans can be installed in a wall. The limiting factor will be the thickness of the wall cavity. Typical construction uses 2" x 4" studs which will limit the number of fans that will fit within this space. Always mount the exhaust fan as high up on the wall as possible. Exhaust fans with lights and units with heating functions should not be mounted within a wall.
Typically a bathroom exhaust fan should be mounted as close to or inside (if rated for tub shower use) to the shower or tub as possible. This will maximize the effectiveness of the unit. Units located in a powder room, should be directly over the toilet.
Only units designed for use with a speed control can utilize one. In general Air King fans should not be put on a speed control. Refer to your specific models specifications to determine if it can.
To maximize your exhaust fan's performance, match your duct size to the original size of the fan’s ducting (do not use a reducer), use the shortest amount of ducting possible, keep the ducting as straight as possible, and if flexible ducting is used, keep it as stretched out as possible to limit the resistance of air flow.
This is typically attributed to one of two causes: 1. When hot air is being exhausted from the bathroom into cold ducting, some condensation might form that will travel back through the ducting, into your unit. This can usually be avoided by wrapping the ductwork with insulation, limited the amount of condensation. 2. In cold climates, ice can form on the roof or wall cap. When the hot air from the bathroom travels across this ice, it melts and travels back down the ducting into your unit. This is a more difficult situation to correct and some dripping might occur. To help minimize the dripping, use a roof or wall cap with a backdraft damper and if possible face it away from the normal direction of the wind during the colder months to avoid ice and snow from building up around the opening.
YES. To properly exhaust air, be sure to duct air outside. DO NOT vent exhaust air into spaces within walls or ceilings or into attics, crawl spaces, or garages. A build up of humidity could cause damage to your home.
Check the grill for build up and clean if needed or check for obstructions in the ductwork. A common obstruction is build up in the roof or wall cap such as birds nests or other debris.
This is probably attributed to one of the following: 1. The motor is loose - turn off power to the unit, remove the grill and check that all screws are fully tightened around the motor. 2. The fan blade is hitting the housing of the unit - turn off power to the unit, remove the grill and check that the blade is fully inserted on the motor shaft.
When the exhaust fan ventilates the air out of the home, the amount of air ventilated needs to be replaced. This is called make-up air or is sometimes referred to as balanced ventilation - balancing the amount of air coming in and out of the home. For older homes the air taken out is typically replaced through what is called natural air infiltration - commonly known as drafts in the home. For newer and tighter constructed homes, a mechanical solution is needed to bring fresh air into the home. If there is not enough make-up air, the performance of your exhaust fan may be diminished and your indoor air quality could be compromised. Air King has many fresh air solutions to choose from.
1. Check that there is power to the exhaust fan. The most common trouble is the circuit breaker is off or there is a blown fuse. 2.Turn off power to the exhaust fan and check that all wires are properly connected. Refer to your specific model's installation instructions for proper wiring instructions.
