Has your air conditioner capacitor started to rust? Is it getting older? If so, replacing it before it fails may save you from an unexpected breakdown during the hottest part of the summer.
At OEMHVACPartsCanada.ca, we offer air conditioner capacitor replacement services throughout Eastern Ontario, including Cornwall, Ottawa, Brockville, Hawkesbury, Alexandria, Winchester, Casselman, Embrun, Morrisburg, Kemptville, and surrounding communities.
Why Replace an Older Capacitor?
Your air conditioner starts and runs because of the capacitor. Every time your system starts, the capacitor is working. Like any electrical component, it wears out over time.
If your capacitor is heavily rusted or corroded, moisture has likely been attacking it for years. Corrosion can eventually damage the electrical terminals, weaken internal connections, and increase the chance of failure.
The question isn't whether a capacitor will fail—it's when.
What Happens When a Capacitor Fails?
A failed capacitor can cause several problems, including:
- Outdoor condenser fan will not start.
- Compressor will not start.
- Air conditioner hums but does not run.
- Poor cooling performance.
- Warm air coming from the vents.
- The evaporator coil may eventually freeze due to reduced or no outdoor airflow if the condenser fan fails.
Replacing an aging capacitor before it fails can help reduce the chance of losing cooling on a hot summer day.
"But My Air Conditioner Was Just Maintained"
Many homeowners assume that because their air conditioner received a maintenance, their capacitor must be fine.
The truth is that an air conditioner maintenance does not extend the life of a capacitor. Capacitors continue to age every year. Unless it is properly tested with a capacitance meter and inspected for signs of deterioration, there is no way to know if it is still performing within specification.
Every HVAC company has its own maintenance procedures, so I can't comment on how another company performs their inspections.
How Can You Check Your Capacitor?
You can perform a simple visual inspection.
- Turn off power to the air conditioner at the breaker.
- Turn off the outdoor disconnect.
- Remove the electrical access panel.
- Locate the capacitor.
Look for:
- Heavy rust or corrosion.
- Swollen or bulging top.
- Oil leakage.
- Burnt or damaged terminals.
Even if everything looks normal, an older capacitor can still be weak internally. The only way to know for certain is to test it with the proper equipment.
