We've had Northwood clean our furnace and air con for years. They even replaced a faulty part in the air con. Good work. No complaints. Until we had an emergency in very cold weather and we tried their emergency line. No one called us back so we went with the first person who did call us back. After the weekend, they called to book an appt to help us. When I told them that we'd left a message on their emergency line, I was told that it was broken and being fixed. When I explained how upset I was to be left, literally, out in the cold in -30, I expected some kind of remorse. The response: "oh well, what can you do?" On the spot, this company that we've trusted for years was fired. Yes, things happen. Phone lines break. But what really bugged me was little to no concern for a valued client. Too bad. Found a great new company.
