Where do I begin??? I called them for service to my office building and was transferred directly…read moreto the service technician. He agreed I had an issue that required him to come and check the equipment, so he scheduled a time with me to come and troubleshoot the fire alarm system. When he arrived I showed him a beeping panel and he said that he needed to check the sensors....an hour later, he came up to me and said he replaced some of the sensor heads, gave me the old ones, and the problem was solved. I appreciate the timeliness and professionalism he gave. I was shocked by the reviews and I am adding my own.

I called the main office and they directed me to call the cell phone of Juan (a worker) who quoted…read moreme $90/hr with a 2-hour minimum. Although I thought this was a very high price, it compared to 3 other companies I called. Juan arrived within 2-hours and fixed the problem within 30 minutes. Very nice guy! When I received the bill, it was for $115/hour. I called the office and let them know of the discrepancy and the gentlemen stated that they are $95/hour not $90. I then asked why I was getting billed for $115/hour and he stated that was their rate. I reminded him that 5 seconds earlier he said it was $95/hour. I told him that I would pay the $95/hour, but that's it. He then stated he had to check with his manager to make sure that was OK. Be careful with these guys and get EVERYTHING in writing. Juan did a good job, but the office needs to brush up on the customer service skills.
