Shopping for HVAC refrigeration compressors can feel confusing because the category covers more than just the compressor itself. One listing may be a complete compressor, while another is a wiring harness or a crankcase heater. The four listings here span a wide listed-price spread, from a low-priced wiring harness to a high-priced auxiliary compressor, so the first decision is matching the part type to the job.
Quick take
If you need a complete scroll compressor, the Emerson Copeland ZP40K7E-PFV-130 is the only scroll-type unit in this group, and its title includes the word Tested. If your repair is limited to a wiring harness, the Copeland Molded Plug Wiring Harness 529-0243-02 is the least expensive entry point. The Freightliner Auxiliary HVAC Compressor Sierra01-0716Y3 is the highest-priced option and is described as new other with cosmetic damage to a plastic module. The Teleflex belly-band crankcase heater addresses 240-volt crankcase heating rather than compression.

Copeland Molded Plug Wiring Harness 529-0243-02
The least expensive listing in this group is the Copeland Molded Plug Wiring Harness 529-0243-02. It is listed as new - open box and carries the model number 529-0243-02 as both the model and MPN. The multicolor harness is a component part rather than a complete compressor, so it suits a repair that already has a compressor in place. Choose it when the job is specifically a wiring harness replacement and you want the lowest listed price among these four listings. The limitation is that an open-box harness may have been previously handled, and it does not include the compressor itself.
OEM HVAC Compressor Belly-Band Crankcase Heater 240V. 142-840018-034
The OEM HVAC Compressor Belly-Band Crankcase Heater is the mid-priced entry in this group. The brand listed is Teleflex and the condition is used. Its role is different from a compressor: it wraps around the crankcase to apply 240-volt heat, helping keep oil warm in cold conditions. This makes it a targeted choice for someone who needs a heater rather than a compressor or harness. The main limitation is that the listing shows a used condition and the manufacturer part number is listed as unknown, so fit information is limited to the model reference in the title.
Emerson Copeland / ZP40K7E-PFV-130 / HVAC Compressor / Tested
The Emerson Copeland ZP40K7E-PFV-130 is the only scroll-type compressor in this group. The title includes the word Tested, and the condition is listed as used. It is a 208/230-volt, single-phase unit with a black finish and a United States country of origin. If you need a scroll compressor and the previous unit is the same model, this listing gives you a complete compressor at a price positioned between the harness and the Freightliner unit on the listed-price spread. The limitation is that it is used, so the condition and remaining service life depend on the previous application.
Freightliner Auxiliary HVAC Compressor Sierra01-0716Y3
The highest-priced listing is the Freightliner Auxiliary HVAC Compressor Sierra01-0716Y3. It is listed as new other, and the description says it was installed and removed but never used, with cosmetic damage to a plastic module and oxidation or paint blemishes from handling and storage. These issues are described as not on the compressor itself. That makes it a candidate if you want a new-other compressor for an auxiliary application and can accept cosmetic imperfections. The limitation is that the cosmetic damage and blemishes mean the external appearance will not be perfect.
Final recommendation by use case
For a budget wiring job, the Copeland Molded Plug Wiring Harness at $19.99 is the clear pick. For a 240V crankcase heater, the Teleflex belly-band at $65.00 covers that specific function. For a tested scroll compressor, the Emerson Copeland ZP40K7E-PFV-130 at $280.00 is the only scroll-type unit here. And if you want a new-other auxiliary compressor and can accept cosmetic blemishes, the Freightliner Sierra01-0716Y3 at $375.00 rounds out the set.
