FAQ

What is an HVAC contactor and why is it important?

An HVAC contactor is a switch that controls the flow of electricity to critical components like the compressor, condenser fan, or heat pump. Without a reliable contactor, your air conditioning or heating system cannot turn on and off safely.

Are HVAC contactors UL-listed?

Our definite purpose HVAC contactors are UL-listed, meeting UL 508 and UL 60947-4-1 standards. This ensures they are safe, durable, and tested for air conditioners, heat pumps, and refrigeration systems. Choosing UL-certified contactors provides peace of mind and compliance with U.S. regulations.

How are contactors used in heating systems?

In heating applications, contactors control the electrical flow to furnace blowers, heat pumps, and electric heaters. A dependable heating contactor allows the system to switch on and off safely, preventing overheating and ensuring efficient performance. At Contactor Depot, we supply UL-listed definite purpose contactors and IEC contactors designed for heating systems, available in 30A to 100A with multiple pole configurations.

Which coil voltages are most common in air conditioner contactors?

HVAC contactors come in different coil voltages depending on the control system. The most common are 24V AC (standard in residential units), 110V, 220V, and 240V AC Coil for larger or industrial installations. At Contactor Depot, we carry all these options to match your system requirements.
