They worked hard, explained questions we had, tested and cleaned up. We still have to decide on some add-on services that seem a bit expensive (also in comparison to the rest of the job). But they have our trust + we hope to stay with them)."

"Furnace was not operating because the company's automatic delivery system ran me out of oil.
Technician showed up promptly and got the furnace operating but could not get heat into the house. Had to reschedule to have zone valves replaced. Technician show up late and didn't have the required parts. Had to reschedule again.
The third technician showed up on time with all the correct parts and worked most of the day to get the system operating properly.
He was completely knowledgeable and very conciencious that everything was working correctly.
