Brands, and what the badge changes
A coil is a coil until it is the wrong one. The replacement has to match the outdoor unit on refrigerant and capacity, and it has to be an AHRI-rated match to keep the efficiency rating and warranty.
- OEM coils from the system brand cost more than universal coils from makers like ADP or Aspen, which many contractors fit. Either can be correct; ask for the AHRI match number.
- Aluminum coils resist the formicary corrosion that pinholes copper coils in humid Texas attics. Several brands have moved to all-aluminum for this reason.
- If the outdoor unit is R-22, a new coil is money into a refrigerant that is no longer made. This is the repair that most often turns into a replacement.
