In the last year or two, we've had protech come in to do various things around the house including a BBQ gas line install, kitchen/stove vent install (some reason they built the house with a vent that never vented outside), various plumbing around the house, furnace, AC, and humidifier install. Overall we are quite pleased with the level of service from protech (you can tell by how many times they have been at my house). I usually have high expectations and even when I have the smallest concern about something, Rick is on top of it and the next thing I know, the guys are at the house to fix it. I appreciate the guarantee I get on protech's workmanship and that's why I keep going back. I definitely recommend these guys.
