"They made sure I understood all of my options and gave me a very good price on a new water heater install. Out of all of the companies I received estimates from, these guys were easiest to talk to and I never felt like they were just trying to make a buck. They beat every other estimate by big margin, though you would not be able to tell by looking at the great job they did. They gave me a full tutorial on the water heater and some helpful info about my furnace as well. I will be using Top Shelf for all of my heating and air needs in the future. I am very impressed!"

"I’m so glad I now have a very reliable plumber with Crossbow. Christopher is so efficient, he takes such care in not getting anything dirty and cleaning up when the job is finished. He finished the job in less time than I thought it would take and did it perfectly. Far exceeded my expectations and I definitely recommend Crossbow Plumbing service. Dennis and Judy Bowns"

"

We had Shane about a year ago when we had a busted water pipe in our garage.  He came out on our "water emergency" and had us repaired in no time at all, so when we needed a plumber again, we wanted Shane back.  He was just as awesome the second time around.

"We have a utility closet in our garage where it was pre-plumbed for a water softener. However, the other equipment in the closet made it a challenge to get a water softener unit in there as well and we were concerned one would fit at all (poor planning by the builder). We had desired to have a larger unit installed, but the space limitation made it very questionable. Matt, the installer, brought out both a large and small unit in case the large one wouldn't fit. But Matt was able to make the larger one fit perfectly without having to redo any of the existing plumbing in the closet (another company had quoted us about $2000 worth of work just to move things around so their water softener would fit). And per our request, Matt went into the crawl space to re-route the garage hose bid to be on the soft water line and ran out and got a shutoff value so the kitchen sink could be switched from hard to soft water. And all this for no additional charge."

"Although the troubleshooting was not solved on the first try, the owner of the company actually came out and got everthing up and running. The problem appeared to not only be a contact, but a clogged filter in the return vent. I will definitely call them again. Customer service was A-1."
