What our customers say
We've had Ross out twice now in the past couple years, and have had wonderful experiences both times. He and AQC are reliable, trustworthy, and responsible! We will call AQC for all needs in the future.
I am the most skeptical person when it comes to hiring people who I don't know, to work on stuff for me. I can honestly say that AQC and Ross far exceeded any expectations that we had. … Great price, great service, very organized and left everything cleaner that it was!
During the installation, Ross noticed something that didn't look quite right with the piping. … He ran a camera through the piping and discovered an actual issue that needed to be addressed. Even more impressively, he fixed the problem without charging us anything extra.
