Heat pumps in Chicago

[Svend W.]

Hi, all

I have an old 2 flat which needs central heat and AC to be added (it currently has gas powered fireplaces and a window AC).

I'm leaning towards going with heat pumps for the following reasons:
* One appliance instead of 2 appliances (i.e., furnace and AC), hopefully reducing maintenance
* Is installed outside, saving space
* It seems to be more cost-effective than a gas-powered furnace over the long term

I will be installing ducts.

I've read warnings about air pumps in cold areas, though.

Curious what people think about this reasoning and/or whether there are types I should use or avoid.

Thanks in advance.
