Furnace & HVAC Replacement Assemblies

A replacement assembly combines several individual components into one ready-to-install unit, which can simplify repairs and reduce downtime compared to sourcing each part separately. Furnace Part Source carries a wide range of furnace and HVAC assemblies for residential and light-commercial heating and cooling systems.

Our assembly inventory includes blower assemblies, inducer motor assemblies, burner and pilot assemblies, conduit and wiring assemblies, valve and stem assemblies, and other multi-part replacement kits from major HVAC brands.

Common Assemblies We Carry

Common replacement assemblies include:

  • Blower and inducer assemblies for airflow and combustion-venting repairs.
  • Burner and pilot assemblies for ignition and burner service.
  • Conduit and wiring assemblies for electrical connections on compressors and motors.
  • Valve, stem, and disc assemblies for water and refrigerant flow control.
  • Motor plate and mounting assemblies for securing motors and blowers.
  • Exhaust vent and NOx insert assemblies for combustion and venting systems.

How to Find the Right Replacement Assembly

Before ordering, check the equipment data plate and confirm the model number, serial number, and existing part number. Assemblies are often model-specific, so matching the exact part number is the safest way to confirm compatibility.

For best fit, compare:

  • Original assembly part number
  • Replacement or superseded part number
  • Unit model and serial number
  • Voltage and electrical ratings
  • System type, such as furnace, air handler, boiler, or packaged unit

Assemblies From Leading HVAC Brands

Furnace Part Source stocks replacement assemblies from Carrier, Rheem-Ruud, York, Trane, Bard, Bosch, Raypak, Bradford White, Copeland, Xylem-Bell & Gossett, A.O. Smith, and other major HVAC manufacturers. Because assemblies vary by model and series, always verify the exact part number before ordering.

Need Help Matching an Assembly?

Not sure which replacement assembly you need? Use the model number, serial number, and part number from your unit to narrow the search, or contact Furnace Part Source for help identifying the correct component. Photos of the equipment data plate and the existing part can make matching faster.

Replacement Assembly FAQs

What is a furnace or HVAC replacement assembly?

A replacement assembly is a pre-built group of components, such as a blower, inducer, or burner assembly, sold as a single part to simplify installation and reduce repair time.

How do I know which assembly fits my unit?

Match the assembly by the original part number whenever possible, and confirm the equipment model number, serial number, and voltage before ordering.

Can I order individual parts instead of a full assembly?

In some cases individual components may be available separately, but many manufacturers only supply certain parts as a complete assembly. Check the product listing or contact us for details.

Do assemblies come with mounting hardware or gaskets?

Some assemblies include gaskets, mounting hardware, or wiring as part of the kit. Review the product description for each listing to confirm what is included.
