Frequently Asked Questions About Ceiling Fans


What is the typical ceiling fan warranty?

Unlike other major appliances in your home that offer extended warranties after one or two years of a standard, new appliance warranty, most ceiling fans offer a lifetime or limited lifetime warranty. Ceiling fans are pretty straightforward devices and have a minimum of moving (and thus breakable parts). Read the warranty information carefully and contact the manufacturer or the seller if you have any questions. The limited lifetime warranties are generally for the larger and more expensive components such as the motor and will often prorate the cost of repair or replacement of these parts.

How does the ceiling fan actually lower the temperature in a room?

The cold hard fact is that the ceiling fan does not lower the temperature. What happens is that you get what is called a chilling effect from a ceiling fan. This chilling effect evaporates perspiration and makes the person feel cooler although the actual temperature in the room stays the same. This evaporation makes you think you are cooler - and what you think is what really matters after all. Think about how it feels to be walking outside on a day when the temperature is fairly high. You're most likely warm and somewhat uncomfortable. Suddenly a breeze comes up and you feel cooler. And, it's a pleasant feeling. On the other hand, picture yourself walking from the heat into an air-conditioned building. While you feel different, it's coldness not cooling you feel.

What about the energy saving factor? Since ceiling fans don't actually cool the air, doesn't your air conditioner setting have to stay the same? The answer is definitely not. Because the chilling effect makes you feel cooler, you can adjust the thermostat up and save on air conditioning costs.

Can a ceiling fan help reduce heating costs?

Rotating a fan clockwise in the winter causes trapped, warm air near the dealing to be forced downward. As you know, warm air always rises and the higher the ceiling the more heat is wasted. This is one of the primary reasons that a reversible ceiling fan should always be purchased. Pushing the warm air downward actually increase the heat in the room and can allow you to adjust your thermostat accordingly. While the energy consumption may be reduced by as much as 8% to 12%, the modest savings in your heating bill will soon add up.

Can I use my current dimmer switch to regulate the speed of the ceiling fan?

Unfortunately, standard dimmer switches are not designed for ceiling fans and using them may, in fact, damage the ceiling fan motor. It's a modest investment to install a switch that regulates the speed of the ceiling fan. Some switches also regulate the brightness of the ceiling fan lights. Don't be penny wise and pound-foolish!

Why do ceiling fans that often look the same cost more?

We have become a society where what's outside is often given more consideration than what is inside. Manufacturers often under pressure from large retail outlets have constructed ceiling fans that have the glitz and glamour of their more expensive counterparts. Believe the old adage that you get what you pay for. Some of the reasons cheaper fans look as good as more expensive ones are found internally. Their motors are usually smaller or of inferior quality. On the outside, designers have found a number of ways to use cheap materials to make a silk purse out of a sow's ear. Resist the temptation to go for what appears to be a great bargain. The ceiling fan you purchase today should be operating smoothly and efficiently ten or more years from now. A cheap unit just won't stand the test of time and you'll. be, in effect, throwing your money away, when you have to replace it with a higher quality unit.

What if my remote control fan does not work after I've installed it?

If your remote controlled fan doesn't work, first check to make sure there is power going to the unit. Check to make sure the control unit is wired correctly. Make sure both the fan pull chain switch and light kit pull chain switch are in their highest setting. Check to see if the code switches in the control unit and hand-held unit are the same.

What if my fan is running slowly?

A faulty capacitor may cause a ceiling fan to run slowly or quit running altogether. There are screws that hold the light kit or switch or housing cap to the bottom of the fan. Remove these screws and take the light kit or housing cap off. Inside the switch housing you will see a small rectangular box. This is the capacitor. Get a replacement from the manufacturer or from where you bought it.

What if my fan does not start?

There are a number of reasons why your fan may not start. First, try checking the main and branch circuit fuses or circuit breakers. Check the wire connections in the ceiling outlet box. (Caution: Make sure the main power is turned off at the circuit breaker or fuse box.) Make sure the forward/reverse switch is firmly in the up or down position. Your fan will not operate if the switch is in the middle. Make sure the shipping stabilizer tabs have been removed from the motor.

What do I do about a wobbling fan?

First, check to see that the screws attaching the blades to the motor unit are all tight. If this doesn't solve the problem, use a yardstick and place it vertically against one of the blades. Slowly rotate the blades by hand to see if they are all at the same angle. If any are not, gently adjust the blade up or down. If this doesn't solve the problem, the fan blades do not all weigh the same. Most manufacturers will include weight-adjusting clips that fasten on the top of the blades. Use a trial and error approach to see which blades need more weight. Start by attaching the clips closer to the motor. If the wobble doesn't stop, move the blades further towards the end of the blade. You may need to do this with more than one blade.

If the manufacturer didn't include these clips, they can be purchased at any lighting store or at most home centers or hardware stores. If you have trouble finding these clips you will need to improvise with such things as masking tape with a coin, etc.

Bathroom Fans - All About Bathroom Fans


Bathrooms were considered to be a place in a house where people tend to give less importance while designing. But lately even bathrooms are being given a lot of attention while designing and building. But still proper bathroom ventilation is missed out by many while designing. Bathrooms tend to be a lot more humid and the bathroom air tends to have excess moisture. This excessive moisture can cause rotting of walls and ceiling and also cause some structural damage. Also, moist surroundings encourage the growth of mildew, bacteria, moulds and many other microorganisms.

To overcome this problem, your bathroom has to be properly ventilated. Some bathrooms have normal ceiling fans installed in them, but they do not do the required job of removing moisture from the bathroom. The best fans that can be installed in bathrooms are exhaust fans. They can eliminate foul odors, remove moisture and also help clear condensation off bathroom mirrors.

An effective bathroom exhaust fan has some standards that have to be met. If you already have an exhaust fan but are not sure about its efficiency then you can go ahead and do this simple test. Just hold a piece of tissue paper up to the grill of the exhaust fan. If the exhaust fan is efficient, the tissue paper will be held tightly to the grill by the fan. Or you can try out the exhaust test. Just place a plastic bag over the exhaust hood and switch on the fan. The plastic bag should be filled with air in a few seconds.

Bathroom exhaust fans are rated by identifying the amount of air it can pull out per minute. They are measured with cubic feet per min (CRM). Bathroom exhaust fans should be rated above 50 CRM to be an efficient and effective one. The Home Ventilating Institute recommends that an effective exhaust fan should be able to provide 1 CFM per square foot. Also if your bathrooms are larger or have bathroom accessory fixtures like steam rooms, sauna or hot tubs, then you will have to invest in a larger exhaust fan. The length of the ductwork to the outside also determines the strength of the exhaust fan that your bathroom should have. The longer the exhaust vent, the stronger your exhaust fan has to be.

Since bathrooms tend to remain closed and compact, noisy fans would test your patience when inside the bathrooms. Make sure that you pick an efficient, quiet exhaust fan for your bathroom. HVI ratings on exhaust fans can be used as a guide to pick the exhaust fan you'll need. Lately bathroom exhaust fans have been launched with light kits embedded in them. Such new varieties of exhaust fans are getting popular as they are multi functional.

So when you go about designing your bathroom don't forget to add the option of an exhaust fan to the design. They will help you to keep your bathrooms less moist and fresh for years to come. Do remember to select the right exhaust fan for your bathroom and regularly maintain the fan to ensure that your bathroom is just the way you want it to be.

All You Ever Need to Know About Ceiling Fans


The controls of a standard ceiling fan include control for three speeds (low, medium, high), as well as there being another control for the light. Some fans are now coming standard with a control for how you want the blades to turn. Of course, they all vary with the manufacturer. To make the controls more easily accessible, a lot of these products are coming with remote controls.

Ceiling fans are typically utilized as a cooling device in the hotter months. They work by pushing air down from the ceiling, which then creates a wind chill effect. In those colder months, a ceiling fan can act as a heat transferor, by reversing the direction of the blades. When doing so, the fan will pull air up, which takes the cold air from the floor and pushes it up so that it is away from you. Remember though, as long as the fan is set at a lower speed, a wind chill will not be created. A fan that operates on reverse has the leading edge of the fan blades as the downward edge; and in most cases this rotation of the blades is clockwise when the operator is standing below and looking upwards at the fan.

As with most things, it is not all that simple. If you have a standard ceiling height, which is somewhere around eight feet, then you will need to run the fan in the clockwise direction during the winter months. Specifically, the ceiling fan blades must be running with the lower edge of the blade being the leading edge into the air. Using the fan with the leading edge of the blade down, will pull the air in the room upward which pushes the warm air hovering near the ceiling out and away and forces it to intermingle with the rest of the air already around.

Even though it is a logical explanation to run the fan in the opposite (counter clockwise) direction pushing hot air down directly, this does create a breeze in the room (giving an undesired 'cooling' effect) and is therefore not effective for normal ceiling heights.

For those ceilings that are higher, more than eight feet, you should run the fan in the counter clockwise direction when cold outside. Specifically, the ceiling fan blades should be running with the top edge of the blade being the edge in the air. By having the leading edge of the fan blade up, it should push the air near the ceiling down towards those in the room. The breeze that is then manufactured by operating the fan in this direction will not be detected at low speeds because the fan height is tall enough that the breeze has become nonexistent before reaching the height of the room.

Once you have the controls sorted, you can create a comfortable atmosphere in your rooms, which will be particularly helpful in keeping you cool in the hotter months.
