Indoor Air Quality Testing
My wife had crazy allergies ever since we moved in our new home and we couldn’t figure why no matter what we tried.
A friend of mine recommended Joel and we hired him. He was amazing! Not only he found our problem (the AC and ductwork were full of mold) he also guided us what should be done to fix it and prevent it from happening again.
I would definitely use him again and recommend him to all my friends and family.

Mold & Toxic Material Test
Joel completely scammed us. We paid him $2000 and he promised he would come and diagnose our air problem in our home to let us know if it was either mold or dander or coming from gas off from the foam insulation(which he didn?t even check). He asked for a check instead of a credit card and cashed immediately. Two days later, he asked for $3600 more to determine ?exactly? whether it was mold or danger and mentioned another $500 to test for the foam. He swore over the phone to me that he would pinpoint our problem for the original $2000 then after he cashes the check and leaves his ?results? are nothing clear and just a statement saying if we want real results we have to cough up more. Completely scammed us and won?t give us our money back.

Mold & Toxic Material Test
I had mold under my refrigerators and I had called several companies, and they all quoted me these ridiculously high prices . I got the call from Joel Fallas and he came over here within an hour. He was so quick. He looked at the problem, I said I was going to pay you for this, and told me what to do to get rid of the mold. I tried to pay him and he said no. He said I will not take your money. I did what he told me to do and I got rid of the mold, and he called me later that day to see how it works and make sure if I was happy,, and I said yes. I just what to tell how honest this man.

Indoor Air Quality Testing
Joel's instruments showed I have very poor air quality. Now, I have to have my HVAC system checked and if that is not the root of the problem, then I have to test for mold although mold is not readily evidenced in the home. Time and next steps will tell.
Response from IAQ Analytical
"$25000 worth of equipment that rents for $1000.00 per day! Without the education and licensing required to be able to operate this equipment and interpret the results, not to mention the long drive to get to your home! Found your issues and guided you to the solution! Sorry that you are upset with the bad results and the truth but you obviously do not appreciate what we did for you. What else do you want from customer service? If I did something wrong, please tell me! But do not give me 3.5 stars for customer service and value for the money based on an emotional response! I never ask for reviews from anyone in 8 years in this business. Every one of my reviews is contrary to yours. ratings except for quality which you gave me 5 stars and that is greatly appreciated. But I do not understand why 3.5 stars. Please let me know if you can! Every one of my reviews is without solicitation!"
