Order oilDirect from the company
J & A Waterville Oil Service, trading as J&A Oil Delivery, is a heating-oil and HVAC company at 943 New Haven Rd in Naugatuck, Connecticut. On its website the company describes itself as a 73-year-old business delivering heating oil and Bioheat fuel and servicing heating and cooling equipment for homeowners across Greater New Haven County, naming Naugatuck, Hamden, Derby, Ansonia, Cheshire, Southbury, Thomaston and a dozen nearby towns, with 24/7 emergency service. The state's licensing registry lists an HVAC contractor licence, HTG.0405698-S1, in the company's name, and the Better Business Bureau accredits it with an A grade. Google customers rate it 3.8 stars across 30 ratings. The recent praise is about deliveries: in October 2026 a customer described driver Brian as pleasant and professional and said owner Anthony was easy to work with from ordering to delivery, and in September 2026 another was added to the schedule the same day after calling in and praised both the office staff and the driver. An August 2026 reviewer trusts the company with heating and A/C issues at a second home and calls it quick and reliable, and in January 2026 a homeowner with a Saturday furnace problem had a technician on site within an hour. The complaints concern service calls rather than deliveries. In June 2025 a long-time service customer said a tune-up took about 20 minutes where it used to take closer to an hour, that a promised call-back about the cleaning never came, and that a billing dispute ended with them asking to be dropped as a customer. In July 2024 a customer went without hot water for weeks while a technician needed four appointments and several parts to fix the problem, and in February 2024 a prospective customer reported six calls and three voicemails never returned. Older accounts on the business's Angi profile, dated 2020 and 2021, praise a technician named Anthony for punctual, fairly priced A/C repairs and installations, but two of them name the company as M&S Mechanical and one 2021 complaint describes an unfinished drywall job, so those accounts may belong to a different firm.
Great experience from start to finish! Brian delivered my oil and was incredibly pleasant, personable, and professional. I also had the opportunity to speak directly with Anthony, the owner, who was extremely helpful, kind, and easy to work with. The entire process, from ordering to delivery, was simple, convenient, and seamless. It’s refreshing to work with a local company that provides such great customer service and genuinely makes the whole experience easy. Highly recommend, and I’ll definitely be using them again!
I called in for a delivery and spoke with Ericka. She was very sweet, understanding, and funny. She was able to add me into the schedule same day. DJ came out and was kind, respectful, and funny. My overall experience was wonderful. A++
Always professional & prompt service
Great service, great advice. Definitely trust them with any heating or A/C issues. I use them on my “holiday home “ so not in the best shape. Always quick and reliable. Highly recommended
Had an issue with my furnace on a Saturday they sent out Chris. HE was here within a hour. He got us up and running . Nice and professional. Thank you
