AC COMPOSITOR HOW TO

It stores and then releases the energy needed to keep the motor going and your AC blowing. Once your unit gets that initial jolt, the run capacitor steps in. The start capacitor is designed to deliver the energy your AC’s motor requires to start the cooling cycle. Systems requiring two single capacitors need a start capacitor and run capacitor to function properly. run capacitors: What’s the difference?ĭepending on how your HVAC system is built, there may be two single capacitors or one dual capacitor in your outdoor unit. In fact, don’t change your AC capacitor yourself because they’re high-voltage devices that could seriously harm you, even if the power is turned off. That means you can’t simply open your unit’s doors and pop a new capacitor inside if it’s time for a new one. They’re connected to wiring inside your air conditioning system. They may look and function similarly to batteries, but capacitors are not batteries. Most capacitors range from 5 MFD (microfarads) to 80 MFD.

Microfarads, meanwhile, describe how much electrical current the capacitor can store. The more voltage in your capacitor, the faster the electrical current moves throughout it. Voltage shows how much electrical current is moving through the capacitor. Once your AC is up and running, the capacitor reduces its energy output, but still supplies a steady current of power until the cycle finishes.ĪC capacitors are measured in voltage and microfarads. It stores electricity and sends it to your system’s motors in powerful bursts that get your unit revved up as it starts the cooling cycle. Always consult an experienced and licensed HVAC technician if you’re experiencing problems with your air conditioner.Īn AC capacitor provides the initial jolt of electricity your air conditioner’s motors need to run successfully. Touching or mishandling one could lead to serious injury or death.

Keep reading for a breakdown of what you should know about the AC capacitor, including how to spot early signs of trouble, AC troubleshooting tips, and what you can do if yours goes on the fritz.īut first, a quick warning: AC capacitors are dangerous, high-voltage devices. Should that happen, your air conditioner will have to work harder to circulate cool air in your space, which can eventually wear out your AC unit or result in higher energy bills. The AC capacitor is one of the most frequently replaced parts of an air conditioner, mainly because it can stop your entire HVAC system from operating if it fails or malfunctions. Your AC capacitor resembles a shiny, cylinder-shaped battery and is responsible for energizing your AC system’s motors to get them running when it’s time to cool things off in your home.

Among the jumbled mass of wires inside your air conditioner’s outdoor unit lives one of the most important components of your entire HVAC system: your air conditioner capacitor.
