I want to recommend MJ Mechanical LLC Heating & Cooling for their services. Contacted them on Sunday night due to an air conditioning repair situation. Adam showed up on time, troubleshoot and identified the problem in a short period of time. He gave me an explanation of costs up front and only replaced the parts that were necessary. He was awesome and highly recommend him and MJ Mechanical. Kudos to them from a very satisfied customer!
