The amount of time air duct cleaning takes can depend on how extensive your duct system is, how old your air ducts are, and whether they have ever been cleaned. On average, expect a standard size home (between 2,000 and 3,000 square feet) to take 2-5 hours for one to two technicians to clean. Here are the proper protocol and equipment you should expect from a professional duct cleaning service, as recommended by the Environmental Protection Agency:
Obstructed dryer vents are the source of thousands of house fires every year. People often ignore or don't recognize the signs of a clogged dryer vent, and this seemingly small oversight can have disastrous results, including the loss of life and property. The best way to prevent house fires from starting in or around your dryer is to have your local Dryer Vent Wizard service your machine and ducts.
“Julian, from Dryer Duct Cleaning services came out and cleared out our dryer vent, It was so clogged it actually leaked water from behind the dryer. I was so happy when he got done.The dryer worked perfectly and it cut the drying time by half. He was on time, cleaned up after himself and very knowledgable. They also came in $50.00 cheaper than anyone else. Appreciate the great Service Julian. Service done on 01/11/19. If there were more than five stars it would have been at the top. Thanks so Much.”
A. First of all, be sure to be there when they do the job! We had our ducts cleaned and got robbed by one of the workers who thought we wouldn't miss a few "minor" personal items. But, even though they didn't believe us at first, we reported it to the police and the company and he got caught! Secondly, ask if they not only remove the vent covers but clean those too. Ask how they clean them and if they use their own cleaning supplies and take the vent covers outside to clean--not in your bathroom or kitchen sinks, using your personal towels. Ask if they clean up the lint that falls into the room with a vacuum cleaner. They should have a crew of at least two people to put the hose in and clean out the vents and one to clean the vent covers and the area around the vents where the lint falls. They should clean the air intake vents and cover also. Some try to sell you on cleaning out your actual AC/HVAC unit coils. I don't see the need for that, but if they insists it is needed, get them to show you the dirt in there that they will be cleaning out. If they can't show you, chances are they will not be able to get in there to clean it. They should change the air filter, but be sure they don't try to sell you some heavy-duty, life-time guarantee filter that supposedly never needs to be replaced. Those don't let enough air flow through. The medium grade ones changed every few months or so work the best. You can buy those at a home improvement store and change them out yourself during the year. Make sure that they don't damage your walls with their big machine, trying to get it down the hall and around corners. They damaged our walls, too and we had to have them plaster and paint it again. Just because the company has a nationally recognizeable name doesn't mean they will do the best job. Often these are owners who hire flunkies to do the work who are thieves and don't care. It would be better to get a local guy that has been doing it a long time and can furnish you with references of satisfied customers.
Our technique cleans your entire dryer vent system twice – once from the outside and once from the inside – so you can be sure the job has been done right. According to dryer manufacturers, your dryer vent must be producing about 96 cubic feet of air per minute at a velocity of 1100 feet per minute in order for your dryer to be operating efficiently and safely. We test your system using a sophisticated thermo-anemometer to be sure that you are getting the proper air velocity and volume at the vent cap.
Since your dryer has to blow exhaust air out through the ducts, the shorter the ductwork, the better. The total recommended length is normally less than 25 feet from the back of your dryer to the outside vent cover. If the duct has bends and turns, it should be an even shorter distance. The more turns, and the further the distance, the harder your dryer must work to move exhaust air and loose lint. A clogged dryer vent means:
"This a very professional company that came the next day after being contacted late in the day prior. The two guys that came to the door that did the work were well dressed and very courteous. They cleaned my diver vent and it works perfectly. I have their literature and will be calling them when I m ready for duct cleaning. Nice equipment too! Thanks for the good work. Nice not to have scroungy guys showing up at the door. "
