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.

Horrible service Horrible service. Billings Alarm sold to them and Mt Alarm who has not even looked up the definition of "CUSTOMER SERVICE" so that they could provide it is not someone I would recommend. They are attempting to make everyone sign a long term contract. They are rude and pushy and accepted $ even though I hadn't signed a contract, yet they are telling me they will terminate it. Not one to be bullied. Run away and don't give them your business.

Once they got here, they did good My initial interaction with Mountain Alarm was very positive. Sales person responded to my initial request within a day. Since then, I have had to follow up a few times to get work scheduled. When they arrive, they do good work and I believe I will get good service in the future. I have had trouble knowing who to contact for what and am still waiting on a couple of responses to inquiries/requests. I have been told the last couple of months have been extraordinarily busy for the company. I can understand that, but not why I do not get responses to emails and calls.

Average Service person had to read from a manual the entire time he was at the residence. It took longer than it should have to resolve the issue and then the bill was unrealistic and not explained.

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.
