Working on a large scale inspection of over 60 buildings and over 300 units. Yumi at Rarefied worked hard to make sure our testing would be completed in a day, she worked her magic.
Special "Thank You" for Yumi for making this all happen! Such a pleasure to work with her. A true professional!!
I would highly recommend Rarefied for your testing needs.
Response from the owner · 6 days ago
We remember this one clearly! We’re so happy that we were able to get everything done in 1 day because we realize how difficult it can be to set notices to occupants who would be inconvenienced that day.
Glad it worked out and we’re ready if you ever have any more projects on the horizon!

I highly recommend Rarefied Environmental for their professional, reliable, and efficient services. They make the testing process smooth and stress-free, which is incredibly important in my line of work.
A special shoutout to my point of contact, Yumiko, who consistently goes above and beyond to make my job easier. Whenever I need testing, she is responsive, helpful, and great to work with. Her communication and ability to coordinate everything efficiently give me peace of mind and allow me to focus on my other responsibilities without the added stress.
I truly appreciate the service and support Rarefied Environmental provides, and I look forward to continuing our working relationship. If you’re looking for a dependable environmental testing company with a great team, I highly recommend them!

Great to hear! Yumi has been key in getting our systems and operations set. It’s very satisfying to hear that the systems in place are working and delivering great results! Thank you for the continued support!

I’ve been working with Rarefied Air Environmental for about 12 years, and Gabe has been the technician on allot of my projects. He is a real asset to the company and always a pleasure to work with. He keeps me informed throughout each project, and I appreciate the care he takes with my customers.
Thank you, Gabe, and the entire team for consistently taking great care of my customers and projects!

Matt Zar with Rarefied Air Environmental is the real deal. He did mold air and surface testing at our property and had the full report back to us right away. It was incredibly thorough and professional, with clear explanations of every finding and exactly what to do next.
What stood out most was his integrity. Another company quoted us $6,000–$8,000 just for an inspection. Matt was upfront that his standard testing is $495 for 4 samples plus $65 per additional sample — a fraction of that. No sales pitch, no scare tactics, just straight answers. He even offered to walk us through the results personally, and he was kind and easy to work with throughout.
With family health on the line, having clear answers meant everything. He's expanding into Orange County from San Diego, and I couldn't recommend him more. If you're in OC or San Diego and suspect mold, call Matt before spending thousands anywhere else. Five stars, easily.
Response from the owner · a month ago
Providing you and your family with real answers and being able to make you understand what was in front of you was very rewarding. Sometimes we forget how stressful and confusing these situations can be for homeowners since we deal with it on a daily basis.
It truly brings myself, lab and all of our employees, on every level, great satisfaction to know that we could help you. And, at the right price!! Good luck to you guys and thank you for the wonderful review!

I have been using Rarefied Air for years in my Restoration Company ; their communication is solid.
I always know what’s going on.
They call when they’re on the way to the site and call when they arrive.
The booking of appointments is streamlined, and there is always availability even on short notice appointments.
I have worked with Gavino, their technician, on multiple occasions and he is great, he is efficient and truly shows dedication to his job.
I will continue to work with rarefied and recommend this company to any one that may use their services.
Response from the owner · a month ago
Thank you, sir! The field technicians definitely grind it out on a daily basis. I’m sure Gabe will be glad to hear the encouraging words! Your continued support will not go unnoticed.

I have worked with Rarefied Air Environmental on countless projects over the years and have always had a great working relationship with their team.
A few people deserve a specific shoutout. Matt is always a phone call away when I have a technical question or come across an unusual situation in the field. His knowledge and experience have been a great resource over the years.
Yumiko has been my counterpart on the scheduling side for probably a decade now. Going all the way back to my earlier years in the industry, I’ve been able to call Yumi when I need to coordinate inspections, clearances, or last-minute schedule changes. Ten+ years of consistency speaks for itself.
And finally, Hans deserves some recognition for doing the day-to-day grind in the field. The guy is an encyclopedia of regulatory and industrial hygiene knowledge and always brings a ton of experience to the jobsite.
Great group of people who do outstanding work.
