I live in the pacific northwest. I have 2 heat pump proposals from different contractors and am looking for comments about them, the 1st is lennox xp21 2 ton with variable speed air handler and 9kw backup.

The other is a Mitsubishi Citi multi pumy-p36nhmu and pvfy-p24EOOA, no electric backup.

The information I can find on the Mitsubishi HSPF shows it at 8.5 while the lennox is 9.5. , and the lennox set up is costing less. Am I missing something about the operating cost of the Mitsubishi, other than being a quieter outside compressor, is there an advantage to getting it?
