What Our Client’s Say

David W. was quick and very professional and had answers to any of the questions I asked. I even had a question about an older smoke detector vs a new one and he was very helpful.
Carol, San Diego, CA
I’ve been a long-time customer of ASI and continue to be impressed. With today’s service call, David was on time, knowledgeable and friendly. He made some excellent recommendations and was very thorough and professional in his work. The price was reasonable and I will continue recommending the company.
Carol, La Mesa, CA
The technician was prompt, and professionally. He reminded me why ASI is called the ‘White Glove Guys’. Neat, organized and pleasant. He identified the problem, made the repair and was gone in a minimum of time without leaving any tracks. I will certainly call ASI the next time I need service.
