Dryer Vent Cleaning

Common laundry exhausts are usually located in apartment buildings, but could also be in laundry mats. The ductwork attached to these exhaust systems can come in all ranges of size and configuration.

Common laundries are used more often than individual dryers; therefore they require cleaning more often (every 6-month to 1 year). - Every time the dryer is used, fibers from your clothes, towels or linens break free and become lodged in the lint trap. The lint trap catches up to 90% of the fibers which leaves 10% + to be pushed through the exhaust system. Most dryer exhaust systems are not short straight runs, they twist and turn from round to square to rectangular. These changes in direction and configuration allow lint fibers to collect and cause blockages and dryer inefficiencies.

Energy Efficiency: With a clogged dryer vent, a dryer can work up to 10 times as hard to dry clothes. If you have to run your clothes through a second dry cycle, your dryer is using at least twice the energy is should, along with reducing the life expectancy of your dryer.

Fire Hazard: As dryer vents load up with lint and soap residue, so do dryers. This mixture is highly flammable and when it gets backed up close to the electric heat element in the dryer, it can easily combust. Consumer Product Safety Commission

Flood Hazard: AIf the condensation does not reach the outdoors in vapour form, the result is moisture buildup in the ductwork. This condensation can build up and start to pool in the ductwork. The water along with the lint entering the ductwork causes blockages to form very quickly.

Trust Air-Vac Services to professionally clean all components of this system. We clean through the lint trap, fan and all attached ductwork. If the complete system is not cleaned, any small blockage can cause dryer inefficiencies and moisture build up. Have a look in and behind the lint traps in your dryers, if there is any lint in this location your exhaust system should be cleaned.

Dryer Vent Cleaning


4 Questions to ask the competition:


1. Do you use hepa vacuums when cleaning from insuites?

2. Do you disconnect the flex hose to access the ductwork for cleaning? Some contractors simply blow compressed air through the lint trap and call it done (1 -2 minutes per unit)

3. Do you guarantee the complete dryer exhaust system will be clean?

4. How do you test the dryer exhaust system to ensure an increase in air flow/ volume after cleaning is completed?

Hi Rise & Concrete Buildings

At Air-Vac Services we provide a few options for property owners and stratas.

IN SLAB DRYER VENT PROBLEMS:

  • Sheet metal lined concrete ducts (usually 2"x12") are naturally cold. Hot, moist lint filled air passes through these ducts whenever the dryer is running. The air cools before reaching the outside and as a result the water vapor (condensation) and lint fibers fall out of the air and settle into the ductwork. If this lint gets wet then dries it turns into a substance similar to paper-mache.

  • These ducts can be partially obstructed with concrete that has dripped through the seams of the sheet metal during construction.

  • Some laundry rooms have been constructed with a cosmetic false ceiling, making it difficult to access the in slab/ 4" round duct joint. This joint is critical to get clean. What happens here is the air from the dryer is forced to make a rapid change in direction. With this rapid change in direction the air velocity is decreased to the point that it will no longer suspend the water vapor and lint, causing the initial blockage.



    Method #1: Outside Cleaning Only

    Cleaning would be completed from outside access. A special tool called a skipper is inserted into each outside vent. Under high-pressure-air, this device shoots forward and everything in its path is pushed to the outside. The skipper goes down the ducting and up to the flex hose at the dryer. As it is pulled back out, all the lint is air washed off of the walls and removed to the outside. This method will not remove all standing water. Balconies need to be clear during cleaning. Lint is extracted to the outside without containment (excess lint is picked up, a light layer could remain)

    Pros:
    Access does not have to be supplied to each suite therefore reducing the cost.

    Cons:
    Internal problems and potential fire hazards cannot be assessed and addressed.

  • Torn or collapsed flex hose
  • Heat element on dryer not functional
  • Dryer itself can be plugged up with lint
  • Some models of dryer’s doors and fans load up with lint


    We cannot guarantee that all of the lint from the flex hose be removed.
    If grills or screens are at the end of the dryer vent, loose lint inside the flex hose may be blown back into the grill or screen after we have cleaned the sheet metal portion of the duct.

    Option:  C.O.D. Sign up sheet cost: Inside cleaning to be scheduled with outside only cleaning.

     

    Method #2: Push/ Pull - Inside & Out

    Cleaning Strategy: PULL/ PUSH
    This cleaning strategy is unique to all others in the industry.

    Cleaning from inside and outside together will require access to suites at Air-Vac Services convenience. Dryers (Lint trap, door & fan), flex hose, grills/flip vent and all attached ducting will be cleaned. Cleaning would be completed by first isolating the duct with vacuum and inserting a pull through agitation device first from inside, then from outside via ladders or boatswain chair.

    Pros:
    The complete system will be cleaned therefore reducing any fire/ flood hazard.
    We can guarantee all lint blockages will be removed from the dryer exhaust system
    Airflow readings can be recorded, before and after, on request.

    Cons:
    Access to all units required in a systematic manner
    Administration time by site manager is required for the length of the project.

    Method #1: Inside - C.O.D. with outside only cleaning

    Dryers (Lint trap, door & fan) & flex hose will be cleaned. Cleaning would be completed from inside with compressed air, pull through agitation devices, high-powered blowers and ladders/ staging.

    Method #2: Push/ Pull - Inside & Out

    Cleaning Strategy: PULL/ PUSH

    Cleaning from inside and outside together will require access to suites at Air-Vac Services convenience. Dryers (Lint trap, door & fan), flex hose, grills/flip vent and all attached ducting will be cleaned. Cleaning would be completed from inside and out together with compressed air, pull through agitation devices and ladders.

    Pros:
    The complete system will be cleaned and any deficiencies reported therefore reducing any fire hazard.
    We can guarantee all lint blockages will be removed from the dryer exhaust system.

    Cons:
    Very time consuming (drives the cost up)
    Administration time by site manager is required for the length of the project.
