Poor response and much more costly than we were led to believe. As a building owner we were caught with a need to correct a problem with an alarm that the original company would not service (or could not because of some license problem). We thought we corrected it, but the new company we hired did not have an in city Denver license. Mtn. Alarm fiddled around, repeated the same procedure we had just done and paid for and then charged a gigantic connect fee. Until I contacted an owner, the salesman only returned calls when he felt like it. Eventually they did get the alarm onto their system and then followed up with a huge bill for doing that. Then a month later they charged a huge fee again for a yearly checkup, even though they should have checked it up while hooking it up. Very u;nhappy, but had no choice as the fire dept. had filed a ticket in my name.

We canceled month's ago after they… We canceled month's ago after they re-upped our contract without us agreeing to it. They are still charging us even after we called in to cancel. These people are the thieves you want to protect yourself from.

Natural born skeptic is a believer in Montain Alarm We hoped for the best with our first alarm service they exceeded that hope every step of the way That is the salesman was polite, professional, and knowledgeable. The installer was timely and competent follow up service calls we made to the alarm center were handled patiently as we worked our way through learning the system. They get my stamp of approval.

Excellent installation and service Technician showed up on time and provided an overview of what he would be doing. He primarily was at our newly built home to connect the alarms to central alarm via the phone line. He checked out the entire system and neatly arranged all the cabling in the wiring closet. He then explained the operation and walked us through setting up codes and password. Could not be happier. Rex was a true professional technician.

Agressive money collection for unknown service Very poor customer service, very aggressive money collecting policy. Will tell you you owe them money for alarm service that you did not know you had and will immediately collect the money by threatening letter and a collection fee on top of that. Cannot recommend.
