She explained the types of tests needed and how she would be collecting them. She also told me if we needed more testing the samples could be used for up to four weeks. We chose Air Quality for their reviews, certification, education, experience and expertise in the field. They also have many California accreditations as well as national and the BBB. Having the BBB A+ certification means they are trustworthy. The price point for each test made it possible for more in-depth testing which is extremely valuable. If you have mold, fire damage, air quality, VOC, water damage or allergens contact Amanda to track down the source of your issue.

I've had a long and complicated issue with mold in my bedroom/bathroom past 3 months and have been…read morethrough several mold testers and remediation companies, and Air Quality Testers is BY FAR the best one. There was an issue with my mold test report from another company and Andrew, the owner, was kind enough to give me a 2nd opinion over yelp messages free of charge, which is why I eventually seeked them out to do a full air testing themselves. Amanda, the technician, came and did a post-remediation air quality test after the mold issue have been resolved and was extremely thorough and careful, exponentially more than the other 2 mold testers that I've used. She answered a ton of my questions with great knowledge and detail, and was extremely helpful in giving me a better understanding of mold and the situation in general. She spent A LOT of time, in contrast to other two mold testing companies that only spent 20mins max. Not only were they more professional, thorough, and answered all of my questions, they also charged me very reasonably for the amount of time and effort they put into their air testing. The last 3 months was quite an ordeal and my only regret is that I did not find this company to begin with. If I have any air quality/mold issues I'll be sure to seek them out again.

We had Chase Home Inspections (recommended by our realtor) do a house inspection in November of…read more2023. We have decided that although this was a bit ago, we're still hurting from this and needed to speak our minds. At first, Austin, who did the inspections, was kind and was willing to answer all our questions. We were pleased, and put our trust in him when he said not bad at all. Upon moving in, we walked right into a major leak in one of the bedrooms, the HVAC was louder than a freight train, and found rodent activity in the attic. We were stunned. We paid $695.00 for this inspection and he was highly recommended by our realtor. Our realtor tried to get Austin to come back out to the house and advise how these items were missed and he wanted another $295. CRAZY. The LEAK: Our realtor noticed the staining on the ceiling and pointed it out to Austin's attention, he dismissed it claiming that it was a previous leak that was fixed and noted that the ceiling discoloration was non-issue. Suggested a good paint job could be done to address it. The HVAC: While we didn't expect the inspector to be an HVAC expert, the fact that he missed it had a big dent on the side of the unit and sounded like a freight train. Oh, and also, we found out the ductwork was in really bad shape. There is a huge difference between saying " the duct work was old and original" to saying " It's old and in terrible shape". The Rodent Activity: Since we had to hire an HVAC person to come out, the other technician found droppings all over the attic and insulation. Something that Austin never mentioned. During the house inspection, Austin wouldn't go into the attic, saying materials were in the way (the previous owners left boxes of decorations in the attic) and it was a small crawl space. We will request a refund and file a report with the BBB. Dishonest inspectors need to be held accountable for their actions. The suggestions, comments, and recommendations provided by Austin made us feel confident moving forward with the purchase of the house. However, if these were more accurate and if he cared, we would have gone in a different direction. We would give zero stars if possible. Please be aware and stay away!
