Guillermo was my McCullough service technician. He was friendly, polite and professional, and kept me updated at all times as to what he was doing. He also made suggestions on potential additions to my somewhat old equipment to keep it in best of repair. I am highly considering his recommendations. 5 stars for Guillermo!

My A/C was not cooling. Shawn May came out and corrected the issue, then did a very extensive and complete evaluation of ALL the A/C parts including the refrigerant and drainage system of my 2006 Lennox for the very reasonable service charge. It's working great now!
