A heat exchanger assembly, comprising:

• a frame for mounting a heat exchanger operably coupled to at least two sides of a heat exchanger housing, said frame comprising:
• at least two mounting rails, each mounting rail comprising:
• a first mounting rail side, and a second mounting rail side, a first end and a second end distal from the first end;
• and
• at least two coil support members extending from the first mounting rail side;
• and
• at least one connection member located on the second mounting rail side;
• and
• at least one support rail configured to engage the second mounting rail side of the at least two mounting rails;
• and
• at least two cross rails operably coupled to each of the at least two coil support members;
• and
• the heat exchanger, comprising at least one coil header, wherein the at least one coil header is operably coupled to the at least two coil support members and to the at least two cross rails.
