On its BBB page the company describes retail fuel oil, heating and cooling services, and its website lists a service area that includes Hartford, Manchester, Avon, Windsor and New Britain. A 2021 customer said they ran out of oil, called at 5am, and had oil delivered by 8am. A 2023 customer said the company had delivered their oil and maintained their heating system for over 9 years. A 2024 customer said that when a boiler failed on Thanksgiving Day, the company had a technician out and the owner followed up, and the job was completed two days later. A 2024 customer said Bruce and Michael replaced an old oil furnace and central air system with a hybrid oil furnace and central air system. A 2025 customer whose heat was blowing cold air said they came to the house within an hour. A 2026 customer trying to get a heating system tune-up said the company did not show or call on two separate occasions. A 2025 customer on autofill said the company never came to refill the oil, leaving them without heat and hot water for 2 days. A 2025 customer said a scheduled boiler service was a no-show with no call, twice. A 2025 customer with a furnace emergency said the company promised visits several times and never came. Its Connecticut S1 heating and cooling contractor licence, HTG.0300612-S1, held by Deitch Energy LLC, is listed as expired. **Strengths:** - Fast oil delivery — a 2021 customer had oil within three hours - A quick heat call — a 2025 customer said they came within an hour **Concerns:** - A missed tune-up — a 2026 customer said they did not show twice - A missed autofill — a 2025 customer was without heat for 2 days ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - Provides retail fuel oil, heating and cooling services, as described on its BBB page _(confidence: medium)_ - [Better Business Bureau](https://www.bbb.org/us/ct/hartford/profile/heating-and-air-conditioning/deitch-energy-llc-0111-87094259) — “About (Better Business Bureau, self-described): Deitch Energy LLC provides retail fuel oil, heating, and cooling services, including install…” - A 2025 customer said the company called back within 5 minutes on a Sunday about an oil delivery _(confidence: medium)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sChdDSUhNMG9nS0VJQ0FnSURCbWNtdHdnRRAB!2m1!1s0x0:0xf3cfbbcd78bf32e8!3m1!1s2@1:CIHM0ogKEICAgIDBmcmtwgE%7C%7C?hl=en-US) — “5★ I've been a home heating oil customer of Deitch for a couple of years now after having issues with the previous oil company I was using. …” - A 2021 customer who ran out of oil said it was delivered within three hours of an early call _(confidence: medium)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sChdDSUhNMG9nS0VJQ0FnSURHbl9mcTdRRRAB!2m1!1s0x0:0xf3cfbbcd78bf32e8!3m1!1s2@1:CIHM0ogKEICAgIDGn_fq7QE%7C%7C?hl=en-US) — “5★ We ran out of oil and I urgently called at 5am. they picked up and had oil delivered by 8am. really appreciative great response time, gre…” - A 2024 customer said Bruce and Michael installed a hybrid oil furnace and central air system _(confidence: high)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sChZDSUhNMG9nS0VJQ0FnSURUdnJ1d0p3EAE!2m1!1s0x0:0xf3cfbbcd78bf32e8!3m1!1s2@1:CIHM0ogKEICAgIDTvruwJw%7C%7C?hl=en-US) — “5★ If You Want to Save $2000 / Year on Heating and Cooling Starting Next Month, Call Deitch Energy Today Bruce and Michael of Deitch Energy…” - A 2024 customer said the company handled a Thanksgiving Day boiler failure _(confidence: medium)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sChdDSUhNMG9nS0VJQ0FnSUMxM2FmUzRnRRAB!2m1!1s0x0:0xf3cfbbcd78bf32e8!3m1!1s2@1:CIHM0ogKEICAgIC13afS4gE%7C%7C?hl=en-US) — “5★ I cannot say enough about the service we received from Deitch Energy on Thanksgiving Day!
