"Ralph and helper Peter arrived on time, went right to work, highly skilled, kept area neat and cleaned up fully after finishing, improved work done by previous plumber, also did two unrelated plumbing repairs for washing machine and a hot water line. Dealt with 1955-built house conditions, first rate results. Very happy with heater, work performance, cleanup, and price. Old heater pickup done separately."

"Very grateful for such an easy and pleasant experience when I suddenly found my very old hot water heater leaking all over the basement floor on a Sunday evening. I did a quick panicked search and thankfully Arctic answered my call and put me at ease with a quote for a replacement and an install appt for first call the next morning. Adam K arrived on time, was very sweet & professional, and installed our new unit in under an hour. Will definitely use Arctic again!"

"We had several different technicians working on installing a new water heater in a crawl space. There were several different unexpected occurrences that arose, but the guys were great. They were respectful, curious, helpful, understanding, knowledgeable and extremely patient explaining our oppositions. They were responsive and prompt to some unexpected situations. Highly recommend them, I'm giving the technicians ten stars for their professional and respectful work ethics."

"This was probably my best experience on Angie's List. I woke up and noticed there was no hot water in the house. Went to the basement and noticed the hot water heater was leaking. I called up Advanced Professional Plumbing, told them what was going on and gave them the specs of the hot water heater. 20 minutes later a technician showed up (a very nice guy named Joey). He inspected everything and showed us the cause of the issue. He gave us a few options on what to do and we decided to replace the 75 gallon hot water heater. Within an hour, Joey came back with Sam and they replaced the old water heater with a new one. They were both professional and got the old hot water heater without making a mess and replaced with a new one. After the job was done, Joey tested all the bathrooms out to make sure the pressure was good and we paid and they were on their way. They were fast, efficient, explained everything and it was a great price. You really can't beat that. Your hot water heater breaks down on a Saturday you are not expecting hot water for the rest of the weekend but Advanced Professional Plumbing delivered. I appreciated the office following with me to make sure everything went. Just an overall class business."

"Travis and Elvis were very professional on the phone. Travis provided detailed information and answered all of my questions to better help me understand between options when I was choosing a new water heater for my home. Travis provided me with a free estimate and stayed within the price range we agreed to when completing the job. The water heater was installed in a timely manner. I also received a follow up phone call to check how the water heater was working and if I had any questions which I appreciated. I would definitely recommend hiring this company and plan to use them again in the future."

"They were great, they were very efficient, courteous, responsive everything worked, the water heater ignition went out, but they came back and fixed the ignition immediately. They were reasonably priced compared to other quotes that we got."
