He was so helpful that I asked him if he knew an electrician (because good look finding one today) and within 5 minutes I had a name and a phone number and I could use NCG for a reference. Want good service.. Call them!!

Sinclair Heating Services are friendly and very nice people. I received service within minutes at…read moremy new residence because they were in my neighborhood! They are knowledgeable, answered questions tha really helped with a decision related to kerosene vs oil. After I chose #2 oil with a low cost additive (which they provided as well), the furnace in my newly purchased home ran more efficient and my home stayed warmer longer. The last tenants used kerosen, my furnace switched on and off like a kid playing with a light switch. With #2 oil with additive, the furnace does not do that, in turn, my electric bill will be lower because it needs electricity to turn on. Other oil companies were not knowledgeable with the use of an oil tanks capability for using oil or kerosen, and highly recommended the more expensive kerosen, which they were not providing at the beginning of the season, plus they advised against it. In addition, one of them had stuffy staff when it came to scheduling and new customers, delivering only on certain days of the wee. I did my online search prior to calling any of them. Sinclair was the only company who knew the grade of oil #2, knew and carried the additive and, that the same tank could be used. Plus, friendly and expedient. Sinclair home heating is a rare find. Janice, very happy customer

A few days later he completed the install and did a satisfactory job. Upon completion Tyler asked if we have any issues in the next 12 months that we contact him exclusively stating that he was "married to it" until then. Approximately six months later the unit began making a strange noise so I attempted to contact him (texts, calls, messenger, email) ....nothing no response. I was forced to call in an outside contractor at my expense (all should have been covered under warranty) Skip forward to 12 months later I realized I had no copy of the receipt so once again I tried making contact and got ghosted. In a text I simply asked for a copy of the $7150 bill and again nothing, so I was unable to claim it on my taxes.
