"New Signature Lennox Furnace"
I purchased a Lennox Signature Modulating Furnace and am very pleased with it. It is so quiet and we now have much better airflow to all rooms. Installation was very neat and professional and the Lennox sales staff were helpful and low pressure. I highly recomend this model

Original Lennox hm30 Replaced with a second hm30. Second hm30 replaced with an hm61. Describe in one word: Junk. It is unimaginable that Lennox would allow a product like the hm30 on the market. I would not have considered the Complete Heat if it had not been a Lennox product.
