Asked for and received an estimate for installation of a ductless mini-split system for a sunroom, but never responded when I asked if there were any units available that were made in the USA. No further follow-up to see if I was still interested.

This is a small company, and as a result, they get tied up with projects, depending on the season. My air conditioner died July 3 2020, and it was close to three weeks before a new unit could be installed. As a curtesy, the sales manager came and installed a window unit in my bedroom so that I could at least sleep at night. I called them 3 weeks ago to install a new WiFi thermostat to replace the unit that I currently have with Vivint. I got a timely estimate and was told by the sale manager he was going on vacation and would get back to me by the end of June. I contacted him and was told that the heat wave had completely filled up the service department with work orders. He said to see if I could get an extension from Vivint (which I had initiated cancellation of services). I'm waiting to see what kind of time frame he anticipates. Overall, they are good to work with, but they do not have a lot of service techs. The price was reasonable for a new a/c unit, and I was given the ability to pay monthly over the span of a year without interest.
