For HVAC technicians and electrical contractors replacing failed motors in residential and light commercial equipment, Century offers a broad replacement motor selection with cross-reference coverage for major OEM applications.

Product Lines

HeatMaster Series

The Century HeatMaster series consists of high-efficiency replacement motors designed for residential and commercial HVAC applications where elevated ambient temperatures are a service factor. HeatMaster motors are rated for continuous operation at ambient temperatures up to 70 degrees Celsius and carry Class F insulation. UL listing is included, and Century backs HeatMaster series motors with a 3-year warranty. HeatMaster motors are available in horsepower ratings and frame configurations appropriate for common residential and light commercial condenser fan and blower applications.

HeatMaster Ultra Series

The Century HeatMaster Ultra series is engineered for HVAC motor applications requiring both UL listing and CSA certification, meeting the compliance requirements of projects that specify both U.S. and Canadian electrical standards. HeatMaster Ultra motors carry Class F insulation and are rated for applications with elevated ambient temperatures. HeatMaster Ultra motors offer the additional CSA certification that the standard HeatMaster series does not include, making HeatMaster Ultra the appropriate specification when both certifications are required on a single motor replacement.

MasterFit Pro Series

The Century MasterFit Pro series is a 48-frame multi-fit replacement motor line designed to replace motors from multiple OEM manufacturers using a single Century unit, reducing the number of part numbers a technician or distributor needs to stock for common residential HVAC applications. MasterFit Pro motors ship with a run capacitor included, eliminating the need to source the capacitor separately on a typical replacement job. The 48-frame MasterFit Pro design covers a wide range of OEM motor applications with a single Century part number.

Pro-E Series

The Century Pro-E series is a 48-frame PSC motor line designed for condenser fan and blower applications in residential HVAC equipment. Pro-E motors are rated for 70 degrees Celsius operation and are built with ball bearings for extended service life in continuous-duty applications. The Pro-E series covers both condenser fan and indoor blower motor applications within the same frame and horsepower range, allowing technicians to specify a single motor line for the most common residential split system motor replacements.

Why Technicians Specify Century

HVAC technicians specify Century electric motors for the breadth of the replacement motor lineup and the cross-reference coverage of common OEM residential and light commercial applications. Century is part of Regal Rexnord, a global motion control and power transmission manufacturer. The Century HeatMaster series carries UL listing and a 3-year warranty, providing documented performance backing for high-temperature motor replacement jobs. The Century MasterFit Pro series reduces inventory requirements by covering multiple OEM motor applications with a single 48-frame part number that ships with a run capacitor included. Century's catalog and replacement cross-reference documentation at regalrexnord.com supports efficient motor selection.

How to Choose a Century Motor

The most important decision variables when specifying a Century replacement motor are horsepower, RPM, frame size, voltage, and application type.

Application type narrows the Century product family. For high-temperature applications where UL listing and a 3-year warranty are required, the Century HeatMaster series is the appropriate specification. For applications requiring both UL and CSA certification, the Century HeatMaster Ultra is the correct choice. For common residential 48-frame applications where a single motor replaces multiple OEM part numbers, the Century MasterFit Pro is the most efficient selection, particularly because MasterFit Pro includes the run capacitor in the package. For standard residential condenser fan and blower applications on 48-frame equipment, the Century Pro-E series covers both with ball bearing construction rated for 70 degrees Celsius.

Horsepower and RPM are the primary technical selection variables. Match the replacement motor horsepower and RPM to the nameplate on the original motor. Common residential condenser fan motors run at 1075 RPM. Blower motors may run at multiple speeds, and the replacement motor must match the speed tap configuration.

Frame size determines physical fit. The 48 frame is the most common residential HVAC motor frame. Confirming frame size, shaft diameter, shaft length, and mounting configuration against the original motor is required before ordering.
