We are a long time customer of Northwood and have found us in the same position as other frustrated customers. We are due for our annual maintenance inspection and it seems the phone is not in service. We had a very difficult time waiting for a call back from them last year. We are assuming that this company has closed. We are extremely disappointed and feel that we deserve an explaination for the lack of communication. Currently, we are looking for a new company to service our furnace.
