Best Smoke Detectors in Los Angeles CA

I'd like to first of alll mention how professional my technician was. He actually showed up EARLY at my residence. He was VERY polite, professional, and very knowledgeable about our electrical problem. Miran H. Was the Certified Electrian that helped us out and I would highly recommend him. Thank you very much United Electric for your assistance. We will ABSOLUTELY use you for our future needs.
