Recently, I was reading through the Healthy Indoors magazine and came arcross this great article by Jefferey C May.
Although I take many air and dust samples in my indoor air quality investigations, I’m going to play the Devil’s Advocate in this article and discuss what I believe are the weaknesses and pitfalls in many areas of mold testing.

Cleaning of air conditioning units in commercial places require more attention and therefore we suggest appointing professional specialists at regular intervals for the job.
It is sometimes difficult for homeowners to maintain their Heating Ventilation and Air Conditioning System. The HVAC System is complex and has many moving machines, that need to function in a systematic way. We might neglect it, but it is important that this is attended to regularly for the systems long term life expectancy.
The main purpose behind HVAC Maintenance is to keep your cooling, ventilation and heating systems running smoothly in all seasons without breakdowns. You have the choice to arrange the maintenance monthly or annually depending on your system requirements.
After your AC system has been cleaned, it is usually disinfected. Now this is a generic term and can range from at worst companies not doing it or spraying water, to disinfecting with bleach or ammonia! So what is disinfection? Why is it done? And how do you know if it is undertaken properly? Read more
The subject of indoor air quality can be intimidating to people. This is because it’s a very under reported and under studied area of human health.
