Removing and replacing old oil tanks is central to A-1 Tankmasters’ customer accounts, including tanks that had to be cut apart to leave the basement. In October 2025, a customer said Lenny and TJ removed a difficult 1968 tank and left no mess. A March 2024 customer described Paul and Joe cutting up a 1941 tank, installing its replacement and leaving the space clean. The company says it serves all of Connecticut, has been in business for 37 years and offers free estimates and 24/7 emergency service. It describes itself as licensed and insured. In March 2025, a customer with a leaking tank said service arrived within three hours; Paul and his crew returned the next day and changed the tank in four and a half hours. A September 2023 customer reported underground tank removal and furnace repair, with timely arrivals and updates while the customer was out of state. Office follow-through and unfinished work drew complaints in January 2026. One customer praised Noah, TJ and third-party contractors Paul and Mike for installing a new tank, but said the old one remained for another three weeks. The customer reported that a $2,600 balance was charged despite an assurance it would wait until completion, and that a promised response about a credit never came. That customer also reported losing heat three times after installation and paying their oil company $690 plus tax for a Tiger Loop. Another January 2026 customer said a subcontractor drove over pool piping against instructions and that the office gave no explanation or solution after more than two weeks. The review raised potential damage, without establishing that damage occurred. In a March 2017 Angi review, a customer disputed the handling of contaminated soil and a proposed additional $6,000 excavation charge after an underground tank removal.
Great people and great services
A-1 disabled my old tank in the crawl space and installed the new Granby tank in the new section of my basement. Noah and TJ along with a third party contractor, Paul and Mike, did a good job. However, they were not able to cut up the old tank and remove it the same day as they ran out of time and had a long drive home from my house. I called Brandon in the main office and he confirmed the balance of the credit card (50%) would not be run until the work was finished. Well, a few hours later they ran the balance on my card of $2600 and frankly we were disappointed that they did the opposite of what we were told on the phone. A-1 came back 3 weeks later to finish the job, chop up the old tank and remove it, which seemed like an eternity and there was some anxiety if they would even come back. When I asked Patricia for a "small" credit for dragging this out to a 4 week job, I was told let me check with the owner and get back to you next week (she did not get back to me - very unprofessional). And the cherry on top was my fuel line now had air in it and I had to install a Tiger Loop ($690 plus tax) with my oil company (yes, I lost heat three times after the new tank was installed on very cold days). My boiler and previous very, very old tank worked fine for 25 years without a Tiger Loop....now I needed one. I have mixed feelings on this whole experience. Customers should not have "mixed feelings", they should be delighted. Noah and TJ, good job! Brandon and Patricia in the office, not impressed. You are better than this level of customer service.
This was an incredibly frustrating experience with A1 Tank Masters. A subcontractor ignored my clear instruction not to drive over inground pool piping and did so anyway. When I raised the concern, it was brushed off with the claim that frozen ground made it “okay,” which is simply not true. What followed was even worse: complete silence and zero accountability. The owner never called me. The office repeatedly said the issue was “being investigated” for over two weeks, yet I received no explanation, no solution, and no follow-through of any kind. Being dismissed and left hanging after raising a legitimate concern about potential property damage is unacceptable. I would strongly caution anyone considering this company.
Lenny and TJ came out and removed a difficult 1968, 12 gauge oil tank with ease. They were extremely friendly and personable. As well as they left no mess. 10/10 service thank you!
Paul and crew were exceptional at replacing my old oil tank. Very detailed, great craftsmanship, high end replacement parts, friendly, courteous and did great work. Walked me through everything that was done after the job was complete. Highly recommend!
