Quoted from yzfguy:I wish these were as affordable as you guys make them out to be. At least in jersey, they are not.I got multiple estimates from large companies and mom and pop shops, and all were about twice what is mentioned here . I have an LG unit getting installed next week for my main floor, bit have to wait til next year to do the upstairs with a separate unit. $$$$ hopefully we love the first and continue on with the upstairs.
Get upstairs done first. Heat rises so that's where most of your load will be.
