 Trustindex verifies that the original source of the review is Google. I was told by another company that my A/C unit could not be repaired, and I was facing a $13K swap of the A/C side of my home. Russ was on time, accommodating, transparent about the condition of the unit and most important, fair with his price to repair. He was able to fix the unit for less than 10% of the estimated cost from the other company. I would highly recommend RM Mechanical for you HVAC service needs.
