"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. All this for a third of the price the big companies wanted to charge me! In addition, he spotted duct work that had been dangerously incorrectly installed on the new furnace and warned me - the company who did the installation has just been over and has agreed to remediate the duct work free of charge. - Alex is fairly young but experienced, a master plumber, fully licensed, and friendly and h"

"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!"

"Service Tech Ed DeMore, who had originally installed our tankless water heater, responded and realised the unit had to be reset and recalibrated after an error message caused the unit to stop and not restart during the snowstorm of last Monday. He had us up and running in just a short amount of time. Eddie is an excellent and knowledgable employee with a great attitude. He is very pleasant and we hope A. J. Perry realises what a great asset they have in Ed."

"Titan did a great job. They were quick and efficient. They installed a new water heater and took the old one away. The area was left so clean that you couldn't tell someone did work there. I would recommend using them to all my friends."

"The owner David Hill came right over. He assessed that I needed a new water heater, ordered the right one and installed first thing in the morning the next day. Great company, I highly recommend."
