AC and HVAC Capacitors Across Canada

XPart Supply carries capacitors for air conditioners, heat pumps, condensers, furnaces, blowers and compatible HVAC equipment. Available products include dual-run capacitors, single motor-run capacitors, start capacitors and related starting components in common round and oval sizes.

Capacitor replacement must be based on electrical specifications, not appearance alone. The replacement should match the required capacitor type and capacitance rating, while meeting the equipment manufacturer’s voltage requirements and fitting the available mounting space.

Information to Confirm Before Ordering

  • Capacitance shown in MFD or µF.
  • Single-value or dual-value rating.
  • Required operating voltage.
  • Run capacitor or start capacitor type.
  • Round or oval shape and physical dimensions.
  • Original part number and HVAC equipment model.
Dual-Run Example 45/5 MFD indicates two separate capacitance ratings in one capacitor.
Voltage Example Use a voltage rating that meets the equipment manufacturer’s requirement.
Shape Matters Round and oval capacitors may require different mounting space.
Part Number Search Use the original number to locate direct equivalents and cross references.

Common Capacitor-Related Symptoms

A failed or weak capacitor may be associated with a compressor or fan motor that will not start, starts slowly, hums, cycles off or operates unreliably. These symptoms can also result from motors, contactors, wiring, controls, low voltage, mechanical problems or sealed-system faults. Proper diagnosis is required before replacing a capacitor.

Electrical safety warning HVAC capacitors can retain a dangerous electrical charge after power is disconnected. Diagnosis, testing and installation should be completed by a properly qualified HVAC technician. Never select a replacement by shape or physical size alone.

Frequently Asked Questions

How do I find the correct AC capacitor?

Match the capacitor type, complete MFD or µF rating, voltage requirement, shape and equipment specifications. Use the original part number and HVAC model whenever available.

What does 45/5 MFD mean?

It identifies a dual-run capacitor with two capacitance values in one component, commonly serving a compressor circuit and a fan-motor circuit.

Are MFD and µF the same measurement?

In HVAC capacitor listings, MFD and µF are commonly used to express microfarads, the capacitor’s capacitance value.

Can a round capacitor replace an oval capacitor?

Electrical specifications must match and the replacement must fit securely in the approved mounting space. A qualified technician should confirm compatibility.

What is the difference between a run and start capacitor?

A run capacitor is designed to remain in the operating circuit, while a start capacitor is used for short-duration starting assistance in equipment designed for it.

Do you ship AC capacitors across Canada?

Yes. XPart Supply ships HVAC capacitors across Canada and also supports shipments to the United States.
