If you suspect a mold problem — either because of visible growth or a musty smell consistently coming from supply vents — cleaning ducts won’t do much good if it doesn’t eliminate the mold. Mold begins with a moisture problem, and the ducts themselves are unlikely to be the source. The most likely culprits are the cooling system’s evaporator coils, which your heating and air-conditioning contractor — and most duct-cleaning companies — can inspect and maintain. Leaky return ducts can also introduce moisture. Again, if you suspect a mold problem, consider having a service company inspect the duct system for leaks.
"I used Home Advisors to locate someone for me to remove my old water heater. Kevin and Chris reached out to me to find out what wasneeded. Within the hour they arrived at my house and old water heater was gone! They were both pleasant and took care of business in 15 minutes. I would definately use them again!!! Thanks Home Advisor an Everclear for your prompt response and calls!!"
The same holds true for the evaporator coils inside your home’s cooling system. Evaporator coils cause condensation, dehumidifying the air before it circulates through your home. Condensed moisture can cause dust and other particles to stick to and build up on the coils. Also, cleaning the collector pan (and the drain spout in the pan) beneath the coils ensures dirt doesn’t build up and get drawn into the system. It also prevents water from accumulating on and beneath the coils, which can cause mold problems.
I called the company and John answered. We set a time for him to come over that was convenient for us both. He came exactly on time and went right to work. He removed all of the vent covers, including some screens that were over the vents that I had no idea were there. He washed all of the vent covers with soap and water and then started to vacuum all of the ducts, doing a complete and thorough job. He was extremely friendly, professional and worked quickly and thoroughly. He even checked the dryer vent exhaust on the roof to make sure it was clear. After he finished vacuuming the ducts, he sanitized them and then reattached all of the vents.
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:
If there is stuff in the ducts, the fact that it’s laying there and not being blown into the rooms is proof positive that it is hurting no-one. The 5-6 exceptions you cite in this article I’ll buy, but only with the caveat that at least some of those could have been avoided by proper protection (during remodeling for example) – and if asbestos/lead/whatever winds up in your ducts- the remodeling contractor should be the one paying to remove it.
Be cautious with companies that offer “whole house air duct cleaning,” urges the NADCA. The company may be using unscrupulous tactics to upsell you once they get started. Before any work begins, always clarify in writing what the job entails and what the cost will be. To protect yourself against fraud, read customer reviews and verify that your HVAC cleaning service has applicable licenses and certifications.
