 Trustindex verifies that the original source of the review is Google. My husband already wrote a review, but I think that Michael deserves two 5 star reviews. He installed an electric car charger for us and he was fantastic about it. He was very honest, and told us things that we had heard before (about needing to fix our panel first), but was fair with the payment and very nice about everything.. He was great. I think we just found our new electrician :) Thank you!!!!!!

 Trustindex verifies that the original source of the review is Google. The actual service consisted of tracking down why one of my electrical heaters in my condo unit was not shutting off after the minimum room temperature had been achieved.  I had a run-away heating situation that had to be solved in a complex, two stage, thermostatically controlled environment; and Mike, figured out the system and discovered the reason for the run-away condition.  The problem was a bad relay control.  Mike is a first rate professional!  Mike installed the new upgraded relays, and all is working super!  I give my highest recommendations to Mike Nelson at Nelson Electrical!
