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.

I have no opinion I don't know yet--haven't had anyone trying to break-in

Timely response and very good monthly rate. I switched from ADT to Mountain Alarm at approx. 1/2 the monthly rate and no switchover cost. Service was prompt and very courteous and they have a local office if I ever need them. The only minor glitch was I haven't yet received an e-mail confirming my no-rate-increase-for-three-years guarantee.

They are not able to deliver. But they keep on charging. I have had the hardest time getting this company to install cameras in our home. Now 5 months after they installed 6 cameras and 8 additional service visits some taking 5-6 hours, the cameras are still not working. They get an A for effort and an F for results. Well meaning, polite but incompetent.

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.
