Claim 8:
9. A method for providing conditioned air to a structure, comprising:
flowing a refrigerant through an outdoor unit external to the structure comprising an outdoor coiled-tube heat exchanger comprising tubing with an outer diameter less than or equal to eight millimeters (8 mm), the outdoor unit comprising a side-flow unit;
flowing the refrigerant through an indoor unit disposed within the structure and comprising an indoor micro-channel heat exchanger coupled to the outdoor heat exchanger and comprising non-circular channel tubing comprising channels, each channel with an external diameter of less than eight millimeters (8 mm), wherein the outer diameter of each channel of the indoor heat exchanger is smaller than the outer diameter of the tubing of the outdoor heat exchanger; and
reducing a pressure of the refrigerant using at least one electronic expansion valve in fluid communication with at least one of the outdoor heat exchanger or the indoor heat exchanger.
