Very professional work and everything was communicated and explained clearly. Besides changing the panel box, every light, switch and outlet was checked and most of them were replaced to meet the safety standards. My home is over 40 years old and is a mix of aluminum wiring and some copper. As well, Armer Electrical did many other requests such as installing a bathroom fan, outdoor and indoor light fixtures and helping me install a new dishwasher. Great service and would highly recommend.
