Michael from Q Indoor Air was professional, responsive and so knowledgeable. He spent a lot of time explaining things to during the process, and had many helpful recommendations for things we could do to improve the indoor air quality of our cottage. I highly recommend Q Indoor Air. read more

I met Mike at a healthy Home Inspection on behalf of a buyer I was representing. We did have to reschedule due to a conflict, but we got the results in time for our deadline. I called him on New Year's Day and he was able to go to Sonoma County the next day to test my rental unit. My tenant had a leak and said she had a "mold sensitivity". The results were good news. I'm pleased that Mike was willing to travel and his pricing is reasonable. I will continue to use him in the future. read more

It took forever to get the lab report back on molds in my mother's house, had to chase Mike down after about 5 weeks of waiting. Now he won't return my calls to help interpret what the report means or what to do about it. Not happy. read more

Again, the "owner" called me and we had a time for him to come and check the issues in my property and ....he never showed up, is this a joke? Please do not even start business with them. read more

As a recent widow I worried that my house may have issues and I wanted to keep me and my sons safe. I called Mike and he came out right away to check my HVAC system and my attic. He also checked for any issues with moisture in my home. He was very thorough and spent time explaining to me what he was doing and his recommendations. He was also very kind and caring during this very difficult time for me and my family. Thanks Mike for taking good care of me and my sons and keeping us safe. read more

My review has changed, I still don't know source of moisture in my home. Moisture Drips forming hitting ground in attic few weeks back. I hired Michael to find the answer of cause of moisture so I can remediate. Needed someone to dig to find answer. Filter was horribly dirty. He said this was source of poor indoor air quality when results came back as no mold on filter. When I email to question the mold inspection results aren't making sense as to cause of mold, I didn't hear back. Nice guy. Just again even with added attic inspection fee, dirty filter wasn't the answer to cure my sick home so my body can begin to heal. I wanted hvac system tested, when M said let's test filter instead. I agreed when I shouldn't have trusted the suggestion. My fault there. Enjoyed his friendliness, but I hired to determine moisture source which is still occurring. read more

This is a response to Michael's apologies offered on Yelp in response to my one-star review. Apologies are great, but empty if that is all that is offered for wasting a client's time. Not only did Michael reschedule my initial appointment several times because the previous client's job was taking so long, but he then ghosted me the following day by not showing up to our new appointment. He also didn't get in touch, either that day or for some days afterwards.. When I finally texted him few days later, he said he was "so sorry" and explained that he'd not felt well but later felt okay and that he'd "gotten held up at another appointment." Hmm. I was his only appointment for that day. I gave Michael a chance to make it right with me by asking for a reduced rate. Completely ignored. Only more apologies here on Yelp (oh, he was in the hospital and couldn't communicate). I wonder if Michael realized that not only did he waste my time, but perhaps I might have a health issue of my own, which is why I'd hired him in the first place? Extremely unprofessional and disrespectful! read more

Very professional and knowledgable, he knows what he's doing. You just set up a time and Mike does all the work.

Q IndoorAir, Michael, came over and has done a very thorough all over home testing for many possible culprits to my physical symptoms. He is very trustworthy and helpful I recommend Michael and Q IndoorAir for your home, too! read more

tl;dr: Michael is extremely knowledgeable, has good prices, quick to respond, and is not trying to upsell you or sell you any products. I highly recommend using Michael for any air quality issues you have. I was having an issue breathing in one particular room of my new home. My wife didn't have much of an issue, but I spent the most time in there and am generally more sensitive. I got Michael's info from my realtor and he came out very quickly. He performed multiple measurements and sent out samples to a lab. He also provided us with detailed information and recommendations for how to have the best air quality in your home. He isn't trying to sell any services or products, which is great. So, you know his advice is just based on his knowledge and experience. The tests showed everything as normal, but Michael suggested replacing the insulation in our attic as upon visual inspection it appeared quite dirty and could be causing problems or the problem could be hidden underneath the insulation. His theory was completely right! When a contractor removed the insulation, they found a previous leak that was fixed left wet insulation that grew mold right above that room. After removing the old insulation and adding back new insulation, the problems are all resolved and I feel great working in the room all day. I'm so grateful to Michael for his work in resolving my issue. Without his guidance, I absolutely would have had a really rough time trying to figure out what was going on. I highly recommend calling Michael for any issues you have with air quality. read more

In our experience, Mike is a one-of-kind resource when it comes to identifying, diagnosing, and addressing known and potential air quality issues. For starters, his work is grounded in broad awareness of the various sensitivities that individuals experience and the range of root issues that arise with regard to indoor air quality. For us, Mike thoughtfully and systematically translated his findings into language that we non-experts could understand, with enough detail so that we could make choices that felt like informed decisions. We appreciated the care and thoroughness with which Mike prioritized the two issues he recently identified in our home: (1) an acute moisture and mold problem in one particular location; (2) an early-stage issue of moisture around window casings in multiple locations including the location of the more-acute issue. Though the two issues share some similarities on the surface, in fact the necessary solutions are quite different. Mike helped us to think through this, recommending that we invest in more-detailed analysis where it truly was needed and providing clarity about how to remedy the two issues we faced. We previously enlisted Mike to assess the air quality in our home several years ago, so we already knew we were working with a true professional. We were not disappointed -- not to mention that Mike's personable and supportive demeanor always feels highly appropriate for the situation, though this friendly demeanor is not something on which we could have counted from just any service provider. read more

Michael's is the rare service where you really feel like they care about you and your issues. He is prompt, responsive, and very pleasant and spent a lot of time with me both on the phone and in my home(twice) to analyze my air and brainstorm possible issues and solutions. Although he is the only air quality inspector I've used, my sense is his pricing is very competitive and, as mentioned, the service is truly excellent. I would use him again and recommend him. read more

Michael was very responsive and friendly. It was very easy to understand his explanation. He gave me the fee upfront, and there was no surprise. I am glad to choose him as the mold inspector. read more

This review is long overdue. I rarely write reviews nowadays unless something extraordinary takes place, good or bad. A member of my family became gravely ill seemingly out of nowhere almost 2 years ago that had doctors even at the Mayo Clinic mystified. While our family was searching for options and looking for answers, I decided to have their house inspected in March/April 2020 to check for any bad pollutants in the air. When I came across Michael's services and told him our story, not only was he there the same day, but he provided exceptional service for us at a moment's notice despite his hectic schedule during COVID times. He even ensured the results of our tests were expedited which normally would have taken weeks to come back. Michael performed a number of tests and inspections around the house which helped answer a lot of questions for us and provided additional context that the doctors were looking for. I can't recommend Michael enough. He's a genuine guy that provides exceptional service. read more

I was experiencing headaches in my rented office, and I had no idea how to determine the cause. I contacted Michael on Friday, and by Monday he was inspecting the space. Michael brought a variety of sensors and tested for everything, all the while explaining to me in just the right amount of detail, what he was doing. After about an hour we were able to determine the likely cause, as well as a plan for mitigating the issue. Michael even followed up with additional recommendations and educational resources. I HIGHLY recommend Michael for air quality testing, and I feel like I got terrific value for the money I spent on the consultation. read more

Michael was amazing to work with. We set an appointment and on the day of inspection, he was very thorough with all his explanations about the areas of concern I had. Pricing was transparent and fair considering all the other quotes I received from competitors. After the inspection, he provided me with a detailed lab report and walked me through all the verbiage of his findings over a phone call. I definitely recommend Michael's services to anyone who is concerned. read more

I was so grateful I booked with Q Indoor air! Michael was kind and extremely knowledgable. He used to be a builder, and helped me, in addition to the mold testing that he came for, figure out a plan to keep my air quality good while doing a future remodel. I was so lucky he came to my house with that wisdom a week before doing a remodel. Saved my lungs! He also gave a very informative pamphlet with recommendations for air purifiers, etc. Really an all encompassing air quality review. Thank you! read more

I am so glad that I found Q indoor air. Before I moved into my new apartment I wanted to make sure that it was safe. Mike was professional, timely, thorough and a good listener! It's an old building that has a sump pump and signs of wear and tear that I really wanted to have checked out. Having an expert like Mike test and assess my place before moving in has set me at ease and I also know much more about what to look for in the future. I highly recommend this business! read more

This was the first environmental test I'd ever tried. I was specifically concerned about the emissions from a commercial gas range in the kitchen with a standing pilot light for a house I'd recently purchased. Mike was incredibly knowledgeable and had a wealth of information about air quality and pollutants. He patiently answered all of my questions and seemed genuinely passionate about creating a healthy indoor environment. He followed up with me regularly and was open to me calling to ask any follow-up questions. Really can't recommend highly enough! read more

When I moving to Avalon Silicon Valley, I was a bit concerned about the air quality, so I go to yelp and find Q Indoor Air. Michael use his professional facilities to test the different components of the indoor air and convinced me that the air here has low VOC. He also educated me how to keep the indoor air freshened since the air flow in my apt is not very good. He also recommends some air filters and air purifiers. Nice guy, highly recommended! read more

Michael and Peter were awesome! They explained the whole process, they were polite, they were respectful, and saved me money. Q indoor air is the only place you need to call to get your indoor air quality checked. read more

What a nice guy and I've been through the mill with mold testing and remediation. So far he's been on time and came back in a hurry when needed too. He has been more thorough than the other people I've used, and he's honest and experienced. Wish I met him in the first place over a year ago! read more

Similar to others, I had a lot of difficulty getting an appointment because Michael's receptionist cannot see his schedule and needs to call him. After getting an appointment, I took the day of work and waited at home, only to be called 15 minutes before the appointment that Michael would not be able to make it that day. We rescheduled for another day the next week, my wife left work early, and he did not show up. No phone call. No follow up. No apology. read more

Helped me over the phone for no charge. Provided useful info. Nice guy. Highly recommend

I recently hired Michael to do a mold test on a home I was in contract to purchase. Michael did an incredibly thorough job of testing the home for mold, including doing both air and swab samples. When the tests came back positive for mold, the sellers of the home hired a mold remediation company to eradicate the toxic mold. Michael then came back to do further tests and he found slight traces of more mold in the air ducts. The remediation company came back to do more work and then Michael came back a third time to run a final test which came up clean. Throughout the entire process I was extremely impressed with Michael's professionalism, communication, and willingness to explain every detail. I would definitely hire Michael again and will likely bring him back in 6-12 months to do another test just to make sure all is still clear. read more

If I could give Mike from Q-Indoor Air 10-Stars I would. Mike has 30-years of experience and is extremely knowledgeable and very professional in his field. He tested the air in my office and gave me a lot of valuable information, and a thorough explanation of why some of my staff were getting headaches. After the inspection, he provided me with detailed results and walked me through all of his findings. He made some really good recommendations that I will use to help me have cleaner air in my office. I definitely recommend Mike's services to anyone who is concerned. Also, Mike is very courteous and helpful. read more

I can't thank Michael enough! He made a very stressful and scary situation very manageable. It was difficult to decide upon a company at first. But when I first spoke with Michael I immediately felt comfortable and very well informed. If you are having any mold issues, you will be in the best hands! He is amazing!! read more

Michael at Q Indoor Air is fantastic. He knows A LOT about mold toxicity and indoor air quality. He has been helping us navigate our indoor air quality situation for the last few months and is super responsive, helpful, and knowledgeable. I think the pricing was definitely very fair, especially considering how damaging mold can be to your house and your health. He was recommended to us by a friend who is a holistic doctor and are so glad to have worked with Michael. Thank you so much for everything! Major life saver! read more

We had a great experience working with Michael! We highly recommend and will definitely work with him again in the future if we ever need his services. read more

A while back we used Q Indoor Air for air quality testing on a 2nd boat owned by a non-profit sustainability group. He previously tested our first boat. He set the appointment to do the work and failed to notice us of any price changes from the fist boat testing he did. When at the job site he then proceeded to negotiate with our non-profit organization in a non-transparent and duplicitous way telling us his prices had gone up and tried to switch the requested service to a far lesser service at nearly the same price. Realizing he was running a bait and switch service type scheme on us we canceled the job. We directly confronted him on this tactic and he got very defensive. As he was leaving he arrogantly commented how he was the only one doing this work and we would not be able to find anyone else to do the work. Also as he was leaving, in a very unprofessional manner, he said we would get our Karma for saying we would let others know about of our experience with him. After this second dealing with this company I now have to wonder if the first set of air quality readings he did for our non-profit were even properly taken, valid or really even accurate. IMHO Lawrence read more

I have to start off by stating that I have a child who has multiple allergies and also suffers from asthma. After moving into a new home, I wanted to make sure the home was safe from any mold or anything that could trigger my son's asthma. I had to move him from one school to another one because each time he was within the school, he had terrible asthma attacks. I later learned the building itself was the cause. Michael was very courteous and explained in great detail what he was doing and why. I was impressed by how knowledgeable he was and understood my concern. I was very happy with my inspection and would happily recommend him. Thanks Michael read more

I am in the middle of my second indoor mold issue. This can truly be a nightmare, And it's hard to know where to start and what advice to follow. I find Michael to be the most practical and well-informed of the opinions I have received. There seem be many ways to view the mold issue. I find many in the profession at large are not necessarily versed in what a major health issue this can be, Michael gets right down to business with a calm and reassuring manner and gets the job done, at very reasonable cost as well, which as we all know can be a big part of the stress. I feel at this point I am learning enough that I not only can avoid mold in the future, I can also create a healthy indoor air environment that can support better health in so many ways for years to come. So much so that I almost think the mold was a godsend. Thank you Michael for all you've done for me. read more

I have used Q Indoor Air to help with severe allergies and environmental issues in two different homes, over a 4 year period. Michael has been highly professional and prompt in every communication and home inspection/testing he's done for me. He is extremely knowledgeable about the source of allergens/contaminants and freely shares *tons* of simple, inexpensive tips one can immediately implement to make a difference in your health. Be prepared to take notes, as he may have a lot of suggestions, but trust me, make them, and the cumulative effect with be a huge benefit to your health and home environment! He may also recommend some pricey solutions (e.g. air cleaner), which with some providers can make me suspicious, but he doesn't actually sell them, so I feel very comfortable with his recommendations. My most recent need to consult with him involved water intrusion into my home, which was greatly complicated by shared responsibility with someone else who hasn't been so cooperative. Michael's knowledge of construction practices, the dollars/cents of construction, corners builders often cut, and the better performing level of materials specifications in rebuilding/mitigation has been invaluable to me. More than anything, I am happy that Michael "gets it" about allergies and sensitivities, appreciates the value of doing something properly the first time, and has the expertise to help improve one's health and home. Mold testing is only a very small part of what Michael can do, and in my opinion, just a first step of what we can do for our own health. Edit: I didn't think to use Q Indoor Air for a pre-purchase home inspection, but wish I did. Michael's level of inspection far outweighs the inspection that was done by the company my realtor recommended. Next time, I'd probably do both inspections to cover all the bases - learnt the hard way as the realtor inspector missed a *huge* issue that lead to the water intrusion that Michael saw ASAP. :( read more

I was a little worried at first about choosing a service with so few reviews. But let me tell you, you don't need to worry. Mike, the owner, not only walked us through every step of the process and brought us information packets on mold but he even called me back multiple times after the job was complete to answer questions I had. I mean, even down to calling me back to give me advice while I was at Home Depot purchasing an air filter. He was amazing. I just can't say enough about him. If you're worried about finding a good company, look no further because Q Indoor Air not only does the job well but cares for its customers. Thanks so much Mike! Will read more

Michael is one of the few honest and trustworthy Inspectors that I trust enough to send my patients to for evaluation of their homes and businesses. I run a medical practice and I know the toxic effects of mold on health and trust Q Indoor Air as a very valuable resource for my patients. Many in this field are unscrupulous and have a very poor education in Air Quality and Construction materials/techniques. Michael is one of the "good guys" and I couldn't recommend him more. He helped a Non Profit group that I work with identify the cause of our water damage and showed us how to easily correct it. He also helped me recently at a home inspection to insure no potential sources of mold existed in the houses. Unlike many specialists in this field who offer testing and remediation ( and therefore have an inherent conflict of interest), Michael just does the testing and can guide the remediation. 5 Stars all around.

I could not have had a better experience than I did with Michael. A few years back I was noticing some black spots on a wall in our condo. Michael came in and did a really thorough evaluation. It turned out water was getting inside one of our walls due to a window not being sealed properly when it was installed - which led to the mold. After sending the mold samples to be tested, Michael indicated it was nothing serious - but I was happy I had Michael check it out and identify the cause. Michael and his team ended up replacing the window for us and it's been perfect ever since. Big Q Indoor Air fans for sure. read more

A business owners biggest nightmare - I saw black dots appear on my wood work at the office. I am in health care so the thought of mold really did not appeal to me. I hired Michael and he walked me through the process, took samples and had it analyzed. Although it was mold, it was not the "bad" type. He told me exactly how to resolve the issue and everything was fine. I really appreciated how nice he is and how well-informed he is. If I have an issue in the future, he is the first one I will call. read more

MIchael made it to my house the same day I called. He's informative, patient and solutions-oriented. He gives honest, great advice, and was able to distill complicated technical information to easy to understand concepts. Every since we implemented a couple simple solutions, I've been sleeping better, breathing better and have more peace of mind that my family and I, including our senior dog, are breathing a higher quality of air! Thanks Michael!! read more

Michael from Indoor Air and his crew were just amazingly great to work with. Michael is very kind, professional and knowledgable, During our mold inspection Michael explained in detail what the issues in the house were, and what we could do ourselves to prevent them. We wish we had hired him to inspect our house when we bought it, then we could have prevented actually lots of the damage. After the lab mold reports came in, we wanted to get a lot of work done on the three story house to get it waterproofed and the air quality back to normal. Michael is also a contractor so he knows how to fix the damage, but he doesn't advertise it, due to a conflict in interest. But I asked him to give us a quote anyways for all the work that needed to be done, which was an overall windows siding repair, replacing an entire corner wall and studs, adding vents to house, fix roof damage, clean and replace gutters, replace an entire deck, and a lot more. We did get different quotes from other contractors to do the different jobs, but we ended up going with Q Indoor Air because they still ended up much more reasonably priced, and we just felt just much more comfortable working with Michael then with the other contractors. We're so happy that Michael made the time to basically fix our entire house, he ended up being a one stop shop for us. And during the entire process Michael stayed in conversation about what was going on, and his workers always cleaned up after they were done! makes a big difference over months of work. So our overall experience was just great with Q Indoor Air, we can breathe again in our home, and we won't hesitate to hire them again for any other major fixes that need to be done! read more

Michael is a life savor! I called him with an urgent need for mold inspection on a retail space as i was about to sign a lease and wanted To make sure the space was clean. I told him I needed to get the results the next day. He then offered to drive the samples down to San Bruno and guaranteed I would get the results the next day. He gave me the results and confirmed the space was clean. He took the worry away from me and I highly recommend him. Great guy, wonderful customer service and affordable. The best!!! read more
