Family members complain about air quality in the home.  They cough or sneeze or have irritated eyes or have headaches or rashes or a variety of other symptoms.  And it happens only when they are in the house.  Looks like you have a mold problem!  Well, maybe not. 

The awareness of mold and mold related symptoms in the indoor environment over about the last two decades has resulted in mold becoming the evident and easy target to relieve these symptoms.  Often after time consuming testing for mold growth and/or airborne mold spores, you often come up empty.  Professionals who do this testing do not come cheap, so the expense can easily induce “sticker shock.”

In order to combat this common scenario, Machado Environmental has developed the inexpensive Indoor Air Quality Basic Health Check.  Delivered by our Indoor Air Quality Professionals, indications of mold are always checked for by an expert eye, but there are a variety of potential air quality issues that we test for with our program.  In relatively short order we test for a number of contaminants that can be found in virtually any home environment.  Included in the Basic Health Check is testing for temperature, relative humidity, carbon monoxide (CO), carbon dioxide (CO2), oxygen (O2) level, total volatile organic compounds (TVOC), Hydrogen sulfide (H2S), combustible gases, airborne particulate, dust reservoirs in furniture and carpeting, and volume of outside air if provided by the ventilation system.  We also perform a hygienic inspection of the ventilation system serving the area plus checking the thermostat setting.  Based on the observations and testing data, we provide a certificate indicating that all parameters are within acceptable limits based on accepted indoor air quality standards.  The certificate is colorful and suitable for framing, if you like.  If there are items outside of these standards, we make recommendations to remedy those factors.  This includes any non-optimum situations observed with the HVAC system.

We perform the Indoor Air Quality Basic Health Check for a single location including the HVAC system that serves the area for a very reasonable fee.  The entire activity is expected to require about an hour.  Additional locations tested during the same site visit would be discounted below the one location price.  If it makes sense or is requested to perform additional testing, such as samples for microbial growth in the ventilation system, there would be an additional charge.  We would only take additional tests or samples, however, after clearing it with you, our client.

You are invited to call Machado Environmental for pricing and to schedule your Indoor Air Quality Basic Health Check.

  1. Hi! I read your blog. Its so nice.A good indication of whether or not to contact us is the state of cleanliness outside the filters. It reflects well that of the ducts.Whether for a new home or not, it is necessary to maintain the entire ventilation system. Furnace ventilation ducts, air exchanger ventilation ducts are favorite places where dust is hidden.NetToyage Echangeurs D'air
