"They called us quickly and got a plumber out within a few days. Super thorough - tested all pipes and water sources to diagnose the problem. They were able to perform maintenance on most bathrooms the same day and improve the water temperature in our showers. Gave helpful, non-biased advice on potential further plumbing improvements. We will likely call this company again for any and all future plumbing needs."

"I stared to look for a plumber after I found water under my water heater. I jumped on Angi and posted my issue. With in minutes....Art messaged me and said he can be her 1st thing in the morning. BTW. This was 10pm at night. His quick response was a plus for me. I had one other respond but he over extended himself to my need. He came at 7amd and said....you need a new water heater. I can got get one and install it now. I was a bit reluctant and he said call me when your ready and left. My wife said his prices looked fair and he seemed like a good plumber. I called him back and said lets dance. He was back at my home in a hour and 1/2...and started the work. He protected my carpet and placed plastic on it. He warned my that maybe the cost might go up due to the age of the pipes and valves. He had the old one out and the new one in an an hour or so. He was quick, clean and polite. I paid him and shuck his hand. I recommend Art for your household plumbing needs. He was excellent."

"I’ll make a short and sweet they arrived on time completed the work very quickly, nice gentlemen. I would definitely hire them again. When friends asked me if I know a good plumber company I definitely will refer them to this one.. They’re very straightforward with the pricing and how much it would cost. They found a bigger issue when they got here and still gave me a great price."

"I called Water Heaters Only out of desperation on Sunday...Seth @ toll free # was fully aware of our tenants being without hot water for 2 days and was able to get a technician out on Monday morning. Monday @ 5 pm, hot water was up and running. David, the technician knew what had to be done to get the heater up and running. The next day, we did have a hiccup with a part but David came out immediately and tweaked the part -- all is good. Here is what I like -- 1. no sales pitch. 2. David gave me a plan b for possible additional work. 3. this company is available 365 days and you dont have to wait for parts to be delivered from out of state. 4. Water Heaters Only has their own facility for parts."
