"Alejandro came out quickly to get me a quote, followed rapidly by Tim and his crew to perform the replacement. We knew the split unit needed replacement, and Tim discovered that the compressor for the main system was shorting out. GAC was able to get me a quote and replace that unit within the week. Very rapid and responsive. Team was incredibly professional and was very careful to talk me through each step. They gave me options when there were routing decisions to make and came to me to ok everything step by step. They left the work areas cleaner than when they arrived too. Office staff is extremely responsive and friendly too. Kudos."
