Guidelines for Selecting an IAQ Consultant
It is important to determine whether you truly need to hire a professional to evaluate or remediate a suspected indoor air quality (IAQ) problem. There is tremendous variability in knowledge and skill levels among individuals providing IAQ services. In addition, there are no federal or state standards or certification requirements for potential service providers, except where it involves asbestos and lead. Consider the following when determining the need for and type of service provider to investigate and/or resolve your IAQ problem.
- STEP 1: Try to identify or solve the problem yourself. Keep an open mind and don’t focus on only one potential issue; doing so may result in missing other possible problems. Start by reviewing MDH indoor air quality fact sheets and recommended resources on our website, located at the bottom of this fact sheet.
- STEP 2: If unsure about your ability to positively identify the problem, determine what specific expertise or equipment is needed to fully investigate the problem. Gather as much evidence as you can about what is causing the IAQ problem.
- STEP 3: Based on your established needs, determine who may be the most qualified professional to perform the task. Interview potential IAQ service providers. Consider asking and checking the following items:
