OEM vs. aftermarket replacement parts: which should you buy?
Both work. OEM parts are made by or for your unit's manufacturer for an exact-fit replacement; aftermarket parts are compatible equivalents that usually cost less.
| Factor | OEM parts | Aftermarket parts |
|---|---|---|
| Fit | Exact-match to the original unit | Compatible equivalent, verify specs before ordering |
| Typical price | Higher | Lower |
| Warranty impact | Safest for units still under manufacturer warranty | Confirm with the manufacturer before installing |
| Best for | Warranty repairs, exact replacements | Budget repairs, out-of-warranty units |
How to find the right replacement part for your unit
Match the part to your equipment before you order to avoid returns.
1. Locate your model and serial number
Find the rating plate on the unit's cabinet, then note the full model and serial number.
- Furnaces: inside the burner door
- AC / heat pumps: on the outdoor condenser
- Air handlers: side or access panel
2. Confirm the part, then order
Search by model or serial, or by part type. Not sure? US-based support can confirm the exact part before you buy.
- Check whether an OEM or aftermarket part is the best fit
- Match voltage, horsepower, RPM, and rotation on motors
- Match refrigerant type and tonnage on TXVs and valves
- Verify electrical ratings where applicable
- Compare physical dimensions and mounting style
- Confirm manufacturer and model compatibility
3. Search by OEM part number (if available)
If you already have the original manufacturer's part number, searching by that number is often the fastest way to identify a compatible replacement.
- Search by the OEM part number whenever possible
- Compare product specifications before ordering
- Verify manufacturer and model compatibility
- Double-check aftermarket equivalents before purchasing
Before You Order
Having the right information ready can help you identify a compatible replacement part more quickly and avoid ordering errors.
- Equipment manufacturer
- Model number
- Serial number
- Existing part number (if available)
- Voltage and electrical specifications
- Refrigerant type (when applicable)
Common HVAC symptoms and the part that's usually to blame
Use this as a starting point, not a diagnosis. If you smell gas or aren't comfortable working on electrical components, call a licensed HVAC technician.
Many HVAC issues can have multiple causes. Use this guide to narrow down possible replacement parts, but always diagnose the system before replacing components.
| Symptom | Likely cause | Part to check |
|---|---|---|
| AC runs but doesn't cool | Failing capacitor or restricted refrigerant flow | Run/dual capacitor, TXV |
| Outdoor unit fan won't spin | Bad capacitor or seized motor | Run capacitor, condenser fan motor |
| Thermostat blank or unresponsive | Power issue or dead thermostat | Thermostat |
| Blower runs constantly or won't shut off | Stuck relay on the control board | Control board |
| Condensate pooling near indoor unit | Clogged or failed condensate pump | Condensate pump |
| Circulator pump noisy or not moving water | Worn bearings or failed motor | Circulator pump motor |
| Compressor won't start but hums | Weak run capacitor | Run capacitor |
Before replacing HVAC parts
Always disconnect power before servicing HVAC equipment. Components such as capacitors can retain electrical charge even after power is removed. If you're unsure about diagnosing or replacing a part, contact a licensed HVAC technician.
Replacement parts glossary
Quick definitions for the parts buyers search for most.
- TXV (thermal expansion valve)
- Controls refrigerant flow into the evaporator coil, adjusting to changing temperature and load to keep the system running efficiently. Shop TXVs →
- Control board
- The circuit board that manages ignition, blower timing, and safety switches in a furnace or air handler. Shop control boards →
- Run capacitor
- Stores and releases electrical charge to keep a motor (blower, compressor, or condenser fan) running smoothly. Shop capacitors →
- Contactor
- A switch that uses a low-voltage signal from the thermostat to close a high-voltage circuit powering the compressor. Shop contactors →
- Circulator pump
- Moves hot water through a hydronic heating system's piping loop, essential for baseboard and radiant heat. Shop circulator pumps →
- Condensate pump
- Removes water condensation from indoor equipment (like a mini split) when gravity drainage isn't possible. Shop condensate pumps →
