We have received Superior Service with Coan Oil Inc! We have used them for the last twelve years and have always received top rated support and Service. Coan Oil has installed a new oil tank, a new furnace and last year they installed the Mitsubishi cooling and heating Units. ALWAYS A PLUS WORK!

Excellent service and knowledgeable technicians. Over the last 30 years they've provided our oil, kept our old furnace in good repair, replaced and service a central a/c unit, replaced an oil tank, and installed a water heater. We've never been anything but happy with their service, pricing, and products.

Furnaces break and/or the heat goes off in winter on cold, weekend nights. No matter, Coan oil comes and solves the problem the same day. They even came on a holiday! Their technicians are efficient, their customer service and billing staff are helpful and kind. Highly recommend this company.

Have been a customer for over 50 years. Coan has installed baseboard heat, a new heating system, a central AC system and a new oil tank. They deliver my oil and provide annual maintenance for my heating and AC systems. They are honest, professional and always on time. They also provide remote monitoring of my heating system while we are away, have a key to my office, and provide service while we are away if necessary. I recommend Coan Oil without any reservations!

I have been a COAN Oil customer since 1979. They have never missed a fill. When it gets to about 1/4 tank, they are there automatically. If I ever have to call, they are always responsive quickly, friendly and professiional. I'm on a yearly contract and they come every May to keep my heating equipment in tip-top shape. I highly recommend them!

We have been long time customers of Coan Oil and always been happy with their commitment to keeping war in the winter and cool in the summer. We have received timely oil deliveries and enjoyed excellent service calls. With that said, we recently received notification that because we do not use a minimum amount of oil, we would no longer receive automatic deliveries and we still do not know what the status of a service contract will be. Needless to say, we are concerned about our relationship with Coan for the winter of 2022-2023.

We have had Coan Oil for more than forty years and they have been wonderful. Friendly staff, competitive pricing, excellent emergency service (including the time my oil- fired hot water heater burst on Christmas morning and had to be replaced so my guests could shower!). They have veteran technicians who do their tune-up and home visits. It's a family operation that treats you like extended family.
