My father and grandfather own an HVAC business, I work there full time as an installation tech whenever I get some time off school. All we install is Carrier products, and 99% is residential, with a basic home system consisting of an outdoor unit/heat pump outside and furnace/air handler inside.
However, I was recently very intrigued by the units at my school. They put in a total of about 115 Daikin Inverter heat pumps, similar style to the one you got. We are very happy with them. Only had them for about 2 weeks of intense heat but they sure are great. They keep up withdemands of of larger buildings and the opening and closing of doors They are still fairly new, but so far so good.
Hope your new system continues to work well for you! Good luck!
