HVACR parts are components used in heating, ventilation, air conditioning and refrigeration equipment. They include electrical controls, motors, capacitors, contactors, compressors, refrigeration controls, valves, sensors, thermostats and many other service components.

Common service parts include capacitors, contactors, relays, transformers, control boards, blower motors, condenser fan motors, pressure switches, sensors, thermostats and other equipment-specific components.

Commercial refrigeration systems may use compressors, contactors, fan motors, pressure controls, solenoid valves, expansion valves, defrost controls, thermostats, sensors and other application-specific components.

Use the equipment model and serial number, original part number, electrical ratings, specifications and manufacturer documentation. Appearance alone is not a reliable way to select a replacement.

Yes. Similar-looking components can have different voltage, amperage, capacitance, horsepower, temperature, pressure, refrigerant or control specifications. Always verify the required rating.

OEM generally refers to a component supplied or specified by the original equipment manufacturer. Some applications may also have approved or appropriate replacement parts depending on equipment requirements.

No. Capacitor type, microfarad rating, voltage rating and application must be correct. Incorrect electrical components can damage equipment or create a safety hazard.

A contactor is an electrically controlled switching device commonly used to energize compressors, condenser fans, electric heat and other HVACR loads.

A transformer commonly reduces line voltage to a lower control voltage used by thermostats, relays, contactors, control boards and other control components.

Pressure controls monitor refrigeration-system pressure and may control or protect equipment based on application requirements. Settings and pressure ratings must match the system design.

A thermostatic expansion valve meters refrigerant into an evaporator based on operating conditions. It must be selected for the correct refrigerant, capacity and application.

Many components and service procedures can be refrigerant-specific. Newer A2L equipment using refrigerants such as R-32 or R-454B must use components, tools and procedures approved for the equipment and refrigerant.

This HVACR Parts category is designed to organize available heating, cooling and refrigeration parts offered through Advanced Service Company LLC's online store. Product availability and specifications should be verified on the individual product page.

Advanced Service Company LLC provides professional HVAC and refrigeration service. Contact the company to discuss the equipment, required repair and whether installation service is available for the specific part and application.

Verify voltage, phase, horsepower, speed, rotation, frame or mounting, shaft dimensions, amperage, capacitor requirements where applicable and the equipment manufacturer's specifications.

Many component failures can be repaired. System age, overall condition, repair cost, efficiency, refrigerant, warranty and repeated failures should be considered before deciding between repair and replacement.

The HVACR category can include parts used in commercial refrigeration applications. Exact availability depends on current inventory and listed products.

Some HVACR repairs involve hazardous line voltage, moving equipment, combustion systems, pressurized refrigerant or regulated refrigerants. Professional diagnosis and service are recommended when the work requires specialized training, certification or tools.

A failed component may be the result of another problem. Accurate diagnosis can help prevent replacing a good part or installing a new component without correcting the underlying cause.

Advanced Service Company LLC serves North Alabama, including Somerville, Decatur, Huntsville, Athens, Madison, Hartselle, Priceville and surrounding communities.
