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 air out of the room, the amount of air ventilated needs to be replaced, this is called make-up air. If there is not enough make up air, the exhaust fan's performance will be diminished. Typically make up air for bathroom exhaust fan's is accomplished by a gap cut at the bottom of the door entering into the bathroom.

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.

On most Range Hoods the model number is located on a sticker on the inside of the hood. You may need to remove the filter in order to see the model number.

MAKE SURE POWER IS SWITCHED OFF AT SERVICE PANEL BEFORE SERVICING THE UNIT. Clean your range hood 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.

The function of a range hood is to prevent flare ups from the cooking surface from burning or in extreme case catching the cabinets above the cook top on fire. Range hood can also provide ventilation, helping to clear the cooking area of smoke, steam, odors, and grease generated from the cooking surface.

Although there are many factors that will determine what size exhaust fan you need, as a general rule, the following will apply: For under cabinet range hoods or hoods mounted against a wall the minimum air flow (CFM) is 40 CFM per linear foot. So a 36" range hood should provide a minimum of 120 CFM of exhaust. This is a mimum. the recommended amount is 100 CFM per linear foot. For a range hood mounted from the ceiling (island mounted range hood), the rates are higher. A minimum of 50 CFM and a recommended rate of 150 CFM per linear foot NOTE: Always consult any applicable building codes in your area in regards to minimum and maximum air flow rates. Certian states may require additional items such as make-up air for larger CFM range hoods (typically over 300 CFM).

As the name implies a ducted range hood ventilates the air in the cooking area outside through ductwork. A ductless or duct free range hood filters the air through a charcoal odor filter and recirculates the air back into the cooking area. A ducted range hood will be more effective and efficient at ventilating the cooking area, but in situations where ductwork is not an option a ductless range hood is a good alternative.

With a ductless range hood, because the air is being recirculated and there is no actual ventilation taking place, there is no standard for measuring the CFM or the sone rating.

NO. The actual size of the range hood will be slightly less than the generic description of the range hood. For instance a 30" range hood will most likely measure 29-7/8". Refer to your particular model for the exact width.

Your grease filter should be washed in hot water with detergent once a month. Make sure the filter is completely dry before reinstalling. Replace the grease filter if it becomes damaged, or too dirty to clean.

NO. Charcoal odor filters cannot be washed and must be discarded and replaced when they become noticeably dirty, have stopped filtering the odors, or at least once per year.

Air King recommends that the range hood be mounted between 20" and 30" from the cooking surface for maximum performance. As always - make sure to consult and adhere to your local and National codes when installing a Range Hood.

To maximize your range hood's performance, match your duct size to the original size of the fan’s ducting, use the shortest amount of ducting possible and keep the ducting as straight as possible. ALWAYS USE METAL DUCTWORK and avoid flexible ducting when possible.

YES. To help make the transition easy, make sure you know if the current unit is ducted or ductless, and if it is ducted, which way the ducting is running and the size. This will help you choose a proper replacement. When replacing a microwave, you will want to consider the height of the microwave compared to the height of the range hood and you might need to make height adjustments to insure proper ventilation.

YES. If installing a range hood that has duct work connected to it (any hoods that do NOT recirculate the air back into the room), 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 and grease could cause damage and/or a fire risk to your home.

Check the filter for build up and clean or replace if needed. If the difficulty still persists, 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 filter and check that all screws are fully tightened around the motor. 2. The ductwork connection is loose - turn off power to the unit and check that the ductwork connect to the hood is tight. Add ducting tape if necessary.

When the range hood ventilates air out of the room, the amount of air ventilated needs to be replaced, this is called make-up air. If there is not enough make up air, the range hood's performance will be diminished.

1. Check that there is power to the range hood. The most common trouble is the circuit breaker is off or there is a blown fuse. 2. Make sure a speed has been selected at the range hood's controls. 3. Turn off power to the range hood and check that all wires are properly connected. Refer to your specific model's installation instructions for proper wiring instructions.

On most fans the model number is either located on the motor, on the rear grill or under the base of the fan.

Always disconnect your fan before cleaning. DO NOT immerse electrical parts in water. Parts may be cleaned with a mild detergent and water. Wipe all other parts with a soft cloth moistened with water and mild detergent only. Dry all parts completely before reconnecting to power source.

NO. Your motor is permanently lubricated and does not need to be oiled.

YES. On units that include a secondary support cable, it should always be installed to provide additional safety.

NO. The power cord is equipped with a three-prong grounded plug that must be inserted into a matching receptacle. Under no circumstances must the grounding prong be cut off the plug. Where a two-prong wall receptacle is encountered, it must be replaced with a properly grounded three-prong receptacle installed in accordance with the National Electrical Code (NEC) and all applicable local codes and ordinances. This work must be done only by a certified electrician, using copper wire only. WARNING: USE OF A THREE-PRONG TO TWO-PRONG ADAPTER IS NOT RECOMMENDED. IMPROPER CONNECTION MAY CREATE THE RISK OF ELECTROCUTION. USE OF SUCH ADAPTERS ARE NOT PERMITTED IN CANADA

NO. By using Air King's Storm Guard feature, your window fan can be installed so that the window can close behind the fan.

1. Check that there is power to the outlet and that the fan is completely plugged in. Two of the most common items are either the circuit breaker is off / there is a blown fuse, or that the outlet is controlled by a light switch. 2. Make sure a speed has been selected with the fan's controls. 3. If your fan has a thermostat feature, make sure it is properly set.

Replacement parts can be ordered from the parts department by calling 1-800-233-0268 Monday thru Friday 8:00 AM to 4:00 PM EST.

Be sure electricity is turned off at the main fuse box before cleaning or servicing. Clean the plastic cover by removing from unit and using a damp cloth with mild detergent. Never use abrasive pads or scouring powders. Completely dry the cover before replacing. The inside of the chime can be vacuumed when build up (dirt, lint, etc.) accumulates over time.

Two conductor bell wire.

Painting an Air King Chime will not effect the performance of the chime, but there are inherent difficulties associated with painting a plastic product. If you do paint your chime, make sure to only paint the chime cover and remove it from the body before painting. DO NOT paint any components inside of the chime.

Yes. To accomplish this you will need to add a pushbutton and increase the size of the transformer. For two entry systems, use Air King model AK16 transformer.

1. Check that there is power to the chime. The most common trouble is the circuit breaker is off / there is a blown fuse, or if your fan is controlled by a wall switch, that the switch is off. 2. Turn off power at the main circuit board and make sure all wiring is properly connected.
