I work for Trane and am very interested in learning more about your experience with the Trane product. We are very concerned about both quality and customer service and routinely go the extra mile to ensure that our customers are satisfied with both. Please provide an e-mail address or a number where I can reach you. Alternatively, you can e-mail me at email@example.com. I would truly like to know more about the service history on the Trane units so we can determine some appropriate action to address your concerns about the product. I do realize it has been some time since the message was posted, but have just now found it. I look forward to your response.
