Methods of Duct Cleaning – Which One?
Contact Cleaning vs Negative Air Cleaning
by Mary Dziak, Marketing Manager
People ask me all the time what method of duct cleaning is better. In my experience, it is not necessarily the method that is used but the cleaner doing the work.
If you are a conscientious person doing the work, either type of cleaning method will get the job done correctly. If you are not worried about the outcome of the job, the work will show that also.
Using contact cleaning (disturbing the debris and collecting from the same point) can be very effective in residential settings with light to moderate debris. Once you get into bigger ducts like in a commercial setting you may want to consider using the Push/Pull (Negative Air) method.
How do you know if you’re doing a good job? A video inspection system can help. If you want to make sure that you are doing things correctly, start doing a “before/after” shot of a couple of different jobs. This will tell you very clearly if your work is done right. It really doesn’t take much extra time. You only have to inspect a couple of supply ducts and/or return ducts, not the whole system.
I know, I always go back to the same thing, but doing a job that fits the customer’s needs instead of just having your hand out for the mighty buck, will go a long way to get repeat and referral business. Isn’t that what we are always striving for?
