"They were prompt, courteous and left everything in good order. They also explained that it wasn't a bad faucet, but the problem was that the opening in the granite was too large and caused the faucet to move and eventually get stuck. This had happened before and the previous plumber didn't make us aware of that. They did a good job."

"Your guys CJ & Andrew were awesome! They did such a nice clean looking job! Super professional and very informative. They walked me through setting up the app for the whole house water shut off valve they installed and now I get a reduced rate on my homeowners insurance. They also found that my water pressure reducing valve had failed and replaced that at the same time. Couldn’t be more happy with the job they did."

"When I first talked to Al he walked me through some items to see if I could do the repair myself. Once we figured out the level of the repair needed he immediately came over the next morning. By noon that day he had replaced my water heater, brought it up to code and charged a very fair amount. He also removed lines and capped them that were no longer in use that was not related to the water heater replacement. Al is old school and I very much appreciated his honesty as well as trying to work through the problem. Two other companies, they remain anonymous but both are on TV, came out and didn't look at the water repair heater to repair but just gave me an extremely high cost to replace. I have found my "go to" plumber. Thank you Al1"

"Overall great experience. Donald, the inspector, arrived early and patiently waited with me for my real estate agent to arrive. Donald did a thorough inspection of the inside and outside units. He was very knowledgable about pertinent laws and regulations and took his time to explain them. He also explained that the HVAC unit is old, but functioning and that it may have to be replaced in a couple of years. When that day comes I will definitely call Carini again, and ask for Donald."

Customers say: Quick response

"I had a brand new water heater installed 5 months ago. It began leaking on Saturday night just as I had a house full of guests staying for the weekend. Disaster! The good old boy plumber that installed it has refused to return phone calls and text messages. Gone. Didnâ t care. . So I was stuck with calling someone who I didnâ t know and get them to do a replacement on Sunday morning. Over a dozen plumbing companies declined. Fortunately I found this company. They came out Sunday morning. Removed the old 75 gallon unit under manufacture warranty and finished the job by late afternoon. ARS did a great job. Morghon Liddel was a real professional. Very neat install. So happy I selected this company. I learned my lesson about hiring a good old retired? Guy, never again. I am very satisfied with ARSrescue"
