How To Know If Your Air Ducts Need Cleaning - Or Not

Air ducts should be cleaned periodically sometimes.

In theory, a duct with a great air filter and no leaks in the ducting is going to get very little in the way of contaminants. However the real world bucks the theory.

When do your ducts need cleaning?

1. When you look in them and see a lot of dust.

We don't give a price for duct cleaning by phone. We come and look first to see if they are dirty. If they are dirty then we want to find the cause - otherwise they just get dirty again.

Here is more than you wanted to know. So skip to #2 if you want to get through now.

If there are leaks in the return then dirty air from the attic or crawl space gets pulled into the ducts and distributed through the home. Unconditioned air is also pulled in making your furnace or AC work harder. If leaks are in the supply then the home becomes depressurized and outside air is sucked in everywhere it can - like the fireplace.

2. If you have allergies that go away when you leave the home or office.

3. If the furnace or air conditioner was running while you had construction going on - dust gets sucked in.

4. If your filter is missized, missing, or plugged.

We install an electrostatic air filter as part of our duct cleaning. We want them to stay clean after we clean them.

5. If rodents got in or water - probably we need to replace the ducting.

Additional Information and duct cleaning options:

Fogging to lock down remaining dust, or, to fog in an anti-bacteria chemical.

We test the ducts for leakage - we can seal accessible ducts and measure for leaks after to see what was accomplished. One small home went from 580cfm loss to 180cfm. An 8" fan can move around 200cfm. They were losing the equivalent of 3 fans blowing to the outside. We were able to reduce it by 2/3!
