Minneapolis Residential HVAC Installers- and the Value of AC

[Joseph Lee]

1) Does anyone have any recommendations for residential HVAC installers that do work in Minneapolis? We have a few furnaces to replace and AC's to install (possibly- see below).

2) What does everyone estimate the value of central air to be in a upper-medium-end rental in Minneapolis? Do you project $x more in monthly rent or see it as something that gets your more interest but not necessarily more rent? For perspective, the units are 2 BRs in a 1960's side-by-side duplex getting $1700/mo, so they're not cheap units from a rent perspective. We haven't had a problem getting tenants, but I'm wondering if it's worth it to get AC installed while we replace the furnaces.

Thanks for the input!
