Installed 10/2020 by slomins. Have called for service 3 times (dec 2020, jan 2021, february 2021). The last two times the carlin burner stops working. Led screen states "no flame". No flame means no heat in february. Called for service and i'm told it will possible take over 9 hours. Besides having slomins install the oil burner, I have a oil burner service contract, house alarm and a/c service contract with the company. At this point I do not trust the oil burner. I consider it unreliable. I'm concerned I will come home to a cold house with frozen pipes. Slomins lack of service and customer support is causing my family a lot stress, anger and grief
