Advance Central Fire Alarm Safety Inc

The carbon monoxide detector alarm was going off every few minutes. My condominium's management suggested I contact AC Fire Alarm Safety. When I placed the call, I was advised to turn off the main power to silence the alarm, & turn off all appliances and immediately get fresh air into the premises by opening doors and windows. The technician was very professional. Replaced the unit as it was no longer functioning properly. I would definitely recommend this company.
