@Brendan Harding Very cool! 

Hot, but maybe cooling slighty.

Another benefit is that with the new efficient blower, I can recirculate air by just having the fan on without using the A/C to cool down the house.Question1: Should I even consider investing in an A/C to make tenants happy and raise the value of the home for refi (double benefits)?

There are a bunch of shady people in the industry, along with a lot of cool people.

My Mountain Biking and outdoor friends speak highly of it - so it seems to have that "cool factor".

@Brent T Galbreath I think solar technology is really cool, but I have never been able to figure out how to make it work on any of my rentals.

I'm trying hard to save as much as possible, but at the same time enjoy life as a 24-year-old living in a cool city like Denver. 

Ok cool.

After reviewing documents and calling the heating and cooling company they used, the company stated that they ONLY serviced the two furnaces and NOT the A/C units.

(Sounds kind of cool to me...)Hope this helps...
