HVAC Feedback appreciated -

I actually work as an Energy Engineer serving the natural gas efficiency programs in the northeast. I cannot discuss project-specific details (which wouldn't matter much as I work in the commercial and industrial sector) but I can offer some advice if you want. Feel free to PM me.

As mentioned above, I would definitely shop around. Trane used to be good, but I'm not 100% on their newer stuff. Lennox and Carrier are two big names I would check out.

I would advise against Ebay. Better results will come from a local vendor using a product he prefers (not necessarily one he gets a cut on- huge difference).

Let me know if I can help in any way. I'm more than willing to lend my services.
