Miller Oil Company

Miller Oil Company works out of Enfield, and its website describes heating and cooling repairs, HVAC installations and tune-ups for homes and businesses in Enfield, Connecticut and its service area. A 2026 customer said Miller Oil replaced their oil furnace, came quickly to quote and didn't try to pressure, scare or upsell them. That 2026 customer said Russ, who quoted the job, was involved the whole time, and that the cost was competitive with the other quotes they got. A 2025 customer had a new boiler installed, thanked Russ and the crew, and called the job neat and clean. A 2025 customer who said they had used Miller Oil for over 25 years listed oil delivery, a new furnace and, more recently, a new oil tank. A 2023 customer said an oil line was replaced and that they arrived on time. A 2024 customer whose oil was getting low on a weekend, with the offices closed, said the lady on the phone got them in touch with a technician and their oil was filled up the same day. A 2025 customer who called as a low-income client said the company helped them get oil for the next day. A 2023 customer said ordering fuel was simple and that they always came the next day. A 2023 customer accused the company of scamming them and said their online account was disabled when they asked for refunds for undelivered oil. A 2023 customer who called to schedule a combustion test on a brand-new unit said they were told on the phone that the company won't touch someone else's work. A 2026 customer who wanted to order heating oil complained that the website showed no price and would not let them make an account without an order.
