Dryer Vent Cleaning







Dryer Vent Cleaning: $125.00


Do you need your clothes dryer vent cleaned?

Cleaning your clothes dryer exhaust duct is an important service. This is a service that is often overlooked and can cause water damage, possible fire hazard, health risk, higher electrical costs and even damage to your clothes dryer.
When a dryer duct becomes plugged you are more likely to experience moisture or water damage. This moisture or water may or may not be visible to you. We commonly retrieve 2-5 gallons of lint, and many times 2-4 gallons of water, from dryer ducts when we clean them.



    

Do your clothes take a long time to dry?

Observing when your dryer vent needs to be cleaned:

  • Clothes (especially towels or jeans) take a long time to dry.

  • Clothes are hotter than usual at the end of the drying cycle.

  • Flapper on vent hood doesn’t open when dryer is on.

Reduced airflow and the resulting lint build-up cause overheating by preventing a fast-enough drying action. When this happens, the high temperature limit safety switch has to cycle on and off to control the heater. Most high temperature limit switches were never designed to cycle on and off continuously which can cause them to fail over a period of time.


Moisture

One of the most important functions of a dryer is the elimination of moisture recovered during the heating of damp clothing. A typical 12-pound load of laundry can weigh as much as 20-pounds when first removed from a washer. The extra 8-pounds is water. That recovered moisture is held as humidity in the warm air produced by the dryer and is normally expelled to the outdoors through the dryer's vent. If this air can not be adequately vented, poor drying will result.
This moisture can also condense into pools of water inside the dryer vent, eventually leaking out. Moisture accumulation inside the dryer ducting is often a sign of poor venting which should be looked into.

Heat

The heat is another important function of a dryer. Many current dryer models have 'one time', non-resettable, thermal fuse or safety. These safety devices will open should the dryer's vent not be installed properly or it becomes restricted. Once this happens, the dryer will no longer heat at all and will require the part to be replaced to correct the condition. On some dryer designs (usually gas) failure of one of these thermal fuses will totally stop dryer operation altogether.
On older models without one of these thermal safeties, poor venting can cause the dryer to cycle on its safety thermostat instead of it temperature control thermostat. This usually contributes to poor drying, can cause overheating and possibly malfunctioning timer advancing on some cycles.
Poor or obstructed venting can also cause the dryer's external cabinet and/or top or control area to get hotter than usual. Without proper air flow the thermostats may not be able to control the heater temperature. The heat created by the heater has to go somewhere, that is usually the cabinet. This is a sign of a very dangerous condition! Operation of the appliance should be discontinued (and possibly even unplugged!) until it can be corrected.

Vent Types and Length

The vent material and the type of outside vent cover being used contribute to the maximum vent length allowed. In all cases the longest possible working vent should be made of rigid metal vent material with a large mouth or louvered outdoor hood. Flexible metal ducting although a bit easier to work with causes reduced air flow due to its corrugated design and will contribute to a lint buildup in the ducting over time. Flexible Nylon ducting is no longer approved in most areas for dryer venting due to the possibility of a fire hazard and has never been approved for use on gas dryers.

In the US all gas dryers must be vented directly to the outdoors by law!
In a properly installed vent, any lint that escapes the dryer's lint filter should be blown right outdoors. Any accumulation which occurs in a dryer's ducting is usually a sign of poor air flow, especially at the location(s) it occurs. In such cases the vent line should be evaluated to locate and correct any deficiencies it may have.

A restriction in the venting can cause lint to build-up
inside the dryer where it is a very real fire hazard!

Poor Venting

   The vent should be as short and as straight and with as few elbows as possible. The more bends and turns, the greater the reduction in air flow there is and more areas where lint can accumulate. More bends will also hamper vent cleaning which should be performed yearly if not seasonally.


Good Venting

  It is sometimes possible to tell if a dryer's vent is the cause of poor drying by totally removing the vent line from the dryer and doing a load. If drying improves, you can be sure the vent is (at least part of) the problem.


Dryer Venting Joints

When attaching multiple sections of vent pipe together, don't use sheet metal screws, use metal foil tape instead. Any protuberances into the vent will cause obstructions where lint can accumulate eventually leading to a restriction. Those protuberances will also make the inevitable cleaning much more difficult.
