That 2026 customer also said they pointed out the condition of her oil tank and saved whatever oil remained in the old tank before replacing it with a new one. A 2024 customer said Mark Miller called almost immediately after an online inquiry about a gas furnace, came within the hour around 6pm on a Saturday and fixed the problem.
