“I found Air Test Guru on the internet. Their website was very informative and I was able to email them a request for an inspection of my house and they got back to me the next day, which by the way it was a Sunday! They came and inspected the house the next day. Lab results came back within the time frame they gave me. Mark Shpizear was very knowledgeable and courteous. We were very pleased with their service”.

Teresa Battaglia, Sherman Oaks

“I’m an active real estate agent in Los Angeles County and have used Air Test Guru many times in the last several years. Their inspections and testing have assisted my clients greatly and have helped provide additional information regarding various properties. In several instances, Air Test Guru has identified problem areas that were the general home inspectors missed. As a result, I have found their services to be vital in a comprehensive evaluation of a property.”.

"Mark Shpizear is clearly an expert in the field."

"Extremely knowledgeable and gave thoughtful, balanced and practical assessments and advice. Used high tech equipment to test and evaluate various areas of concern in my home and even alerted me to a problem, which, if not caught it early, would have been hugely detrimental (and costly!)....before it caused any major damage to my home."
