 Trustindex verifies that the original source of the review is Google. Truly the best!  My husband and I had a large project at our new home and interviewed several different electrical service companies.  We went with 4A for several reasons.  Henry was very upfront and honest.  The men working for 4A are all professional, knowledgeable and polite.  It was important to me that I feel like I could have these men in my home at any given time and feel safe.  My husband wasn’t always there so I dealt with vendors from many companies.  I can honestly say 4A was the absolute best!!

 Trustindex verifies that the original source of the review is Google. Arrived as scheduled, knowledgeable, friendly, professional,  explained what was being done and was upfront about costs.  I've tried a few electricians for various projects but felt best with these guys and their awesome communication and work.  They replaced the breaker in my electrical box for my dryer and checked everything in the box since it was already open.
