A Clean Burn waste oil heater with a few problems is the job one recent customer called Yankee Service Co. LLC about. That customer said Jason and his team responded very quickly, and that Jason quickly identified and fixed a few issues before they came up with a plan moving forward. A different recent customer had a rough time. They had the company do routine maintenance on a waste oil heater in their shop and said the heater was damaged by carelessness, and that the company wanted to sell them a new system for $10K plus, which they turned down. A 2022 reviewer wrote of a fast turnaround. On Google the company holds 4.7 stars from 13 ratings. Its Connecticut HVAC license, HTG.0405735-B1, is active on the state registry, with YANKEE SERVICE CO LLC as the holder of record. Its website lists Clean Burn furnaces, coil tube boilers and SunFire radiant heaters among its products.
I had this company do a routine maintanence on my waste oil heater in my shop. I had no issues with my my heater ! They damaged my heater by their carelessness and mention things that were not true. They wanted to sell me a new system for $10K + plus. I denied. Buyer Beware !!
