"This company is a treasure! I had a gas leak last week in the heart of the coldest weather in ten years: PSE&G just shut off the gas and left; and Alex was the only plumber who responded, to my urgent calls for help as the house cooled down. He was reassuring, came that day to take a look, arrived punctually with a helper the next day, and did a 3-hour repair (it involved work outside and in a crawl space) quickly, efficiently, and professionally. He cleaned up thoroughly, and left me with heat back on and hot water restored. PSE&G came the next day to remove the red tag and approve his work.

"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!"

Customers say: True professional

"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."
