Remember; think about your air system as the lungs of your home. Then consider the type of company that you want to handle your home’s lungs and your indoor air quality within your home. Have the complete air system periodically inspected for contaminated duct work and have it properly maintained so your Heating and Air System can provide your family with good air quality for years to come. Qualified air duct cleaners will follow strict standards set by the National Air Duct Cleaners Association. Allowing an unqualified contractor to clean your ducts could be worse than not having them cleaned at all. More particles could be broken up and released into your home or your HVAC system could be damaged.
Mold in the air ducts can be an easy DIY fix. First, turn OFF your HVAC system. Find an approved cleaning solution. Pour or spray the solution on the infected area. Put on protective gear and a mask - you do not want to make contact with the mold (or chemicals! or breathe it in. Scrub the area using disposable towels or brushes, and be sure to check the drip pan and evaporator coils. Vacuum the affected areas after cleaning. Bag all your rags and utensils and dispose of properly. Apply an inhibitor to the affected areas to prevent future growth. It is recommended to call a professional if you have more than 10 square feet of mold as this may be too big of a job, or there might be other/larger issues. Even if you don’t have more than 10 square feet of mold, you can still call a professional to clean it up.
Air duct cleaning service cleans the supply, intake, and return ducts of standard household HVAC systems (heating, ventilation, and air conditioning). You probably know it as your central air system. Other parts that should be cleaned during a standard duct cleaning include fans, motors, heat exchangers, grills, registers, housing units, and the coils of the HVAC system.
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.
