Green Air Ducts

As I write this, a service company is cleaning our air ducts. I think it really needed to be done, and hope that the result is both a cleaner indoor environment and a more efficient heating and cooling system. When I looked at the filter it was really bad - in fact, we have never cleaned our air ducts before, and we have lived here for seven years.

The service companies say that we should 1) change air filters every 4 months; 2) clean ducts every 2 years; and 3) do a massive system clean every 10 years. Since it's been so long, we're doing the massive system clean, which is expensive, but hopefully well worth it.

We're also going with a reusable air filter that we will have to wash every four months and will reduce our waste, as typical air filters are disposable.
