Our fridge temp was running high and everything was melting. Vladimir took our call on Saturday evening and said he would contact us Sunday morning with a time. Sunday 9am he called and was able.to come at 11. He called ahead and.was on time. He was very friendly and quickly diagnosed that the control board was failing. He had a replacement board in his truck and had the repair done in 30 minutes. His service call fee was also less than others who we had called who would not come out on the weekend. I highly recommend Vladimir and would use him again.
