New member, been lurking trying to educate myself a little. My wife and I are considering replacing an existing heat pump and have been receiving quotes from several installers. At the same time I have been researching the different brands and models to understand the differences. In researching Lennox, one of the models that caught my eye was the Signature series XP15. However, the quote I got from an installer that deals Lennox equipment did not include the XP15 in their quote and when asked about it they said it was being discontinued. Can anyone confirm this? The unit is still listed on the Lennox website.
