How to Maintain & Clean Exhaust Fans in the Bathroom and Kitchen

On the other hand, purchasing the most expensive fan on the market is also illogical. First and foremost, existing ductwork and electricity will greatly affect your total bathroom fan investment.

If neither is in place, your new fan bill just went up. If there is an existing bathroom fanthe ductwork that provides the necessary airflow is already in place. The electric wires and switch supplying power to the fan is also something that can greatly affect the cost.

In most cases, if there was an existing fan, the electrical wires are also already run. Of course, with safety being the first priority, as long as there are no frayed, crimped or damaged wires, there is no need to replace them. On the other hand, if new ductwork and electricity are needed, this greatly increases the price on both labor and materials. Generally, this requires a licensed electrician to run new wires and install a switch, as well as a plumber to install the air ducts themselves.

The involvement of additional subcontractors, or even just additional labor itself, is the main reason the price can substantially increase. In addition, most people do not supply their own raw materials — such as wire, switches, electrical boxes or ductwork — making it very easy for the contractor to mark these items up a substantial percentage.

Again, the installation of a brand new bathroom fan may add a few hundred dollars more for labor and material costs related to a renovation, but it can save money in the long run.Hiring a professional to perform household maintenance may offer convenience and peace of mind, but you can do many of these jobs yourself with no experience or special tools. Your bathroom and kitchen exhaust fans share the same primary function: to move air from those rooms and vent it outside the home.

But there are big differences in the benefits these two types of exhaust fans offer. Most bathrooms are small and few have large, easy-to-open windows to assist with ventilation, so the exhaust fan is often the only escape route for steam. In the short term, this will produce mildew, mold and all kinds of funky odors. Over the long haul, it can peel wallpaper, rot drywall and even warp wood trim and furnishings. Bathroom exhaust fans also do double-duty by clearing out unpleasant bathroom odors.

In the kitchen, exhaust fans are located either in a hood above the stove or as part of an above-range microwave assembly. But it also removes strong cooking aromas, clears smoke from failed baking experiments and keeps cooktops clean by sucking up grease particles.

In the bathroom, feel free to run the exhaust fan anytime you think the air could use some freshening up. But you should always run it during hot showers and for about 20 minutes afterward, or until the steamy air is completely removed.

Kitchen fans also remove cooking smells, and some home cooks might see it as a waste to let all those delectable aromas escape. The most important times to run the exhaust fan are when cooking with oil or grease, boiling water or clearing smoke. If your fans are quiet, it can be easy for this to go unnoticed. Kitchen hood exhaust fans should also be cleaned at least once a year and can be a little more complex, so we recommend referring to the model-specific documentation whenever possible.

There are two important reasons to seek out model-specific cleaning instructions, and they have one thing in common: grease. Kitchen exhaust fans have grease filters that prevent your vent pipe from getting gummed up, and while most kitchen exhaust fan mesh filters can be cleaned and reused, some are designed to be thrown away and replaced. No matter how hard your filter works, there will always be a little grease that gets through, and cleaning your greasy kitchen exhaust fan blades thoroughly may take a little time and elbow grease.

If your fan uses reusable filters, the most effective way to remove built-up grease is often to soak them in boiling water for several minutes, then scrub with hot soapy water and a nylon bristle brush. And as with your bathroom fan, always shut off the power at the circuit breaker before cleaning.

Unscrupulous home installers have been known to take shortcuts by venting exhaust fans into attics or even into gaps between walls. This just means that humid air is being moved to an inconspicuous place where mold could grow for years before becoming a major problem. Depending on the layout of your home, you may be able to visually inspect all of your exhaust fan vent pipes in your attic. In multi-story homes, this can be more tricky, and it can be helpful to hire an HVAC professional for an inspection if you have concerns about your exhaust fan systems.

Dampers are designed to flap open and expel air while fans are blowing and to cover the vent pipe the rest of the time. But dampers can become rusty or damaged, and they can be obstructed by windblown debris.

You should periodically inspect them from the outside, especially if you discover drafty air descending from one of your exhaust fans. A broken or obstructed damper can usually be spotted from the ground.

If you suspect your damper has rusted shut, turn on your exhaust fan and watch it from the outdoors. The average life of a bathroom exhaust fan is about ten years, and kitchen hood fans tend to hang in there a little longer at around 15 years.

Remember: use your exhaust fans, and clean them at least once per year.

Please advise. Thank you for your assistance in the matter. Hi, Kathleen! If the existing venting can be changed or altered to allow that, it would definitely work much better to exhaust the hot moist air. A larger exhaust fan may also be needed and I would suggest you check the calculators available at Broan. Good luck with your project!

The condensation stays in the bathroom,when I turn the fan on! Do I need to buy another one?Bathroom fans direct excess moisture and unpleasant odors out of the bathroom through an exhaust system that leads outdoors, keeping your bathroom fresh and mold free. A bathroom fan can be wired to come on with the room light, have its own power switch, or be on a timer switch that shuts the fan off automatically.

Keep in mind that a fan is an electromechanical device that is subject to failure with repeated use and needs to be replaced periodically. Monitor your bathroom fans for signs that it is failing.

Most bathroom fans cannot be repaired and must be replaced when they fail. As the bearings are typically part of a sealed unit, they cannot be greased. When the bearings quit working or seize, the fan eventually fails and must be replaced. Pay attention to how quickly the fan powers up.

When the fan seems sluggish or powers up slowly, this could mean that failure is imminent. Turn the bathroom fan or combination light and fan on. When the fan does not come on, the circuitry in the fan may have failed. When you know the switch has power, this is indicative that you need to replace the bathroom fan.

The lower the sone value, the more comfortable the listening environment. Sones are not decibels or volume, but rather how sound is "sensed". Our dampers are specifically designed to remain open slightly when the fan is off. This protects the unit from over-heating when the light only is being used and will allow any accumulating heat to be removed from the housing and into the duct work.

Any backdraft in the ducting will cause the damper flap to close, preventing outside air from entering the room. Rough service incandescent bulbs are not recommended for Broan-NuTone light fixtures due to the higher heat output and bulb geometry differing from a standard A19 bulb. Even by following these guidelines, the bulb may still have shorter than expected life or reduced light performance as not all bulbs are created equal.

If the bathroom is larger than square feet, www. Choose a fan with a CFM rating appropriate for your room size to ensure adequate ventilation. Continuous ventilation provides today's airtight homes with a relatively constant and controlled lower level of ventilation. Broan-NuTone bathroom exhaust ventilation fans are designed to provide adequate cooling for motors and lighting, as well as products with integral heaters. Some Broan-NuTone bath and utility fans may be wall mounted.

See the specifications for specific models. Improper installation may affect fan life, safety and your warranty. Range hoods are specifically designed to handle grease and high temperature environments. Ventilation provided by Broan-NuTone fans is only a supplement for odor and moisture removal in the kitchen. Static pressure is the measurement of airflow resistance as it is pushed through ductwork which reduces the effectiveness of the fan.

How to Clean Your Bathroom Fan - Greater Toronto Contractors

Exhaust fans should be located in or near the shower or tub, and in an enclosed water closet. Keep exhaust points opposite the supply air source to ensure that the fresh air is drawn through the room.

Bathroom doors should not be sealed too tightly at the bottom in order to allow "makeup air" to enter the room when the door is closed. The exhaust outlet is the point where air is discharged through the body of the fan housing into the ductwork.

During installation, orient your fan with the exhaust outlet pointing toward the exit vent on your roof or wall to minimize turns in ductwork that impede airflow.

If windows and mirrors are very cold, condensation can still form on these surfaces. And if your bathroom is sealed tightly, replacement air may not be entering the room fast enough to displace the moist air. Be sure to undercut your door sufficiently to draw fresh air into the room.Last Updated: January 30, References. This article was co-authored by Mitchell Newman.

Reattach the wires and vent pipe, and you're ready to test your fan out. Just make sure you're comfortable working with electrical wiring before you begin!

Mitchell Newman. Make sure that the fan is strong enough to ventilate the bathroom before buying. Fan strength is measured in cubic feet of air moved per minute CFM.

Most fans move around 90 CFM, which is good for average-sized bathrooms. If your bathroom is especially large, you might have to look for a stronger fan, which would be bigger or spin faster. To replace a bathroom fan, all you need to do is remove the old fan and install a new one in its place using the same wiring and connections. Begin by removing the screws on the cover of the old fan so that you can access the wiring.

Then, ensure the power is switched off by using a voltage detector and disconnect the wiring to the fan. Detach the vent pipe from the old fan by either removing the clips or the tape that holds it in place. Next, take out the vent fan housing to completely remove the old bathroom fan. To install the new fan, place the housing of the new fan into the ceiling or wall framing and connect the vent pipe, which is the large, silvery pipe that transfers air from the bathroom.

After that, attach the wiring of the new fan to the wiring in the ceiling or wall.

Pay attention to your breathing during your workouts. Keep challenging muscles by slowly increasing weight or resistance. The right weight for you differs depending on the exercise. Choose a weight that tires the targeted muscle or muscles by the last two repetitions while still allowing you to maintain good form. If you can't do the last two reps, choose a lighter weight. When it feels too easy to complete add weight (roughly 1 to 2 pounds for arms, 2 to 5 pounds for legs), or add another set of repetitions to your workout (up to three sets).

If you add weight, remember that you should be able to do all the repetitions with good form and the targeted muscles should feel tired by the last two. Stick with your routine working all the major muscles of your body two or three times a week is ideal. You can choose to do one full-body strength workout two or three times a week, or you may break your strength workout into upper- and lower-body components. In that case, be sure you perform each component two or three times a week.

Here are ten tips to make your vacation the stress-buster it really should be.

If you only take a vacation once in a while, it puts a lot of pressure on that time period for everything to be perfect. A three-day getaway is nice and a week-long one is quite common, but 10 could be the magic vacation number. Traveling with kids adds unique challenges, especially when you have to schedule around nap and feeding times. All you need is some extra planning and preparation for a smooth trip.

Most of us go the DIY route when booking our trips, but a travel agent can save you time and stress when you have a complex vacation planned, such as traveling with a group or you have health issues that need to be accommodated. If you like crowds and long lines, visit a popular destination in prime tourist season.

Otherwise, you might enjoy your vacation more if you head somewhere less popular, like one of these suggestions from Lifehacker readers, or take a staycation. Similarly, the summer might not be the best time for a vacation, depending on where you go.
