I have used JN Electrical Temperature Control, Inc. in the past. I needed the relay on my air conditioner unit replaced. The work was delayed because they had to order the part and the service technicians were a bit behind as well so it took about three to four weeks for them to complete this job. They are very friendly and very professional to deal with so I did not mind the bit of wait I had. The air conditioner is up and running great now so I feel they did an excellent job!
