Capacitors
Capacitors kickstart the motors that run HVAC systems. They’re electrical components that store energy and then release it to start the motor. There are 3 common types of capacitors used in residential and commercial HVAC systems: start capacitors, run capacitors, and dual run capacitors....Read more
The name of each capacitor is a fitting descriptor of its function. Start capacitors provide the initial jolt of electricity to kickstart the motor. Run capacitors help the motor run by maintaining consistent voltage, ensuring efficient operation. Dual run capacitors work the same as standard run capacitors but can support both fan and compressor motors within a single unit.
Capacitors are prone to wear and do require replacement every 5-10 years, though high-usage units may demand replacement sooner. Be on the lookout for any bulging, leaking, or low capacitance as a sign the capacitor is ready to be replaced. If you don’t replace the capacitor in time, fuses can be blown, breakers can be tripped, and motors and be burned-out.
Whether you’re looking for a Mars oval run capacitor, a Carrier start capacitor, or reliable capacitors from Daikin, we’ve got you covered. To prevent your HVAC motors from failing to start, overheating, or drawing excessive currents and consuming more energy, make sure you stock up on capacitors from LONG PartsPros!
