Maintaining Your System

Learn about options to protect your system and see step-by-step instructions for periodically replacing batteries in your equipment.


Homelife equipment installed by Cox is covered for 90 days after purchase under manufacturer warranty that covers both parts and labor.

Equipment Service Plan

The Homelife Equipment Service Plan (ESP) extends the warranty on your Cox Homelife devices due to any unforeseen hardware or system failures for a small monthly fee. The plan covers (a) Homelife devices or parts, (b) labor for service repairs/replacement of faulty devices, (c) system malfunction, (d) service call fees*, and (e) battery replacement service and installation charges.

  • Sign up for ESP within 90 days of installation and avoid the $99 Preventative Maintenance Inspection.
  • After 90 days, we’ll send a technician out to inspect and certify your system for $99 before adding the Equipment Service Plan to your account.
  • Once you have ESP, you qualify for a 50% savings off the recommended annual Preventative Maintenance Inspection fee of $99.
* Customers may see a service charge should the issue be related to equipment not installed by Cox, improperly self-installed devices, or if the problem is determined to be customer-caused.
