Recurring Home Alarm Service Costs

Monthly service fees for monitoring systems range from $10 to $65 but don't include maintenance costs. Most system maintenance means either technical support, which comes free with monitored or unmonitored systems or replacing parts.

In some cases, your warranty covers parts. But the process for repairs requires you to send your part to a service center and have them inspect it. They'll determine if it's a fixable issue or if you need a replacement. This process isn't covered in monthly fees. You'll often need to pay for shipping, and it can take weeks.
