Your HVAC system is a fundamental part of your home’s comfort, and the capacitor found inside it is among the many components responsible for its continuous operation. It is also prone to failure, and when that happens, the system becomes ineffective, being unable to function as intended. Understanding the causes behind the capacitor failure of HVAC systems can help you stay on top of any problems that might compromise their performance.
Common Causes of HVAC Capacitor Failure
Several factors contribute to HVAC capacitor failure. These include:
- Normal Wear and Tear. It is the most common cause of HVAC capacitor failure. Just like other parts of your HVAC system, it has a lifespan, typically ranging from five to 20 years.
- Overheating. This often happens when the air conditioner runs continuously during hot summer months or if the unit is exposed to direct sunlight for prolonged periods.
- Electrical Overload. Power surges or voltage irregularities can damage the capacitor, causing it to malfunction and fail. In turn, the HVAC system stops working, wreaking havoc on your home’s comfort needs.
- Poor Maintenance. A lack of heating and air conditioning maintenance can lead to the deterioration of capacitors. Failing to maintain and service your HVAC system can result in problems that could have been prevented with regular check-ups.
Symptoms of a Failing HVAC Capacitor
There are indicators of a failed HVAC capacitor. Look for inconsistent cooling, where some rooms are warmer or colder. An unusually high energy bill may indicate a struggling capacitor that is causing the system to work overtime. Check the HVAC system for odd sounds as well. When the AC starts, a clicking sound may indicate a capacitor on the verge of failure.
Calling Your HVAC Technician for an Inspection
To determine if capacitor failure is indeed the reason for the inconsistent comfort in your home, a professional air conditioning repair is a necessity. A certified technician can accurately diagnose and fix this particular issue. If the system itself is past its lifespan and is breaking down, it might be time to consider a new one. A new system may be a more cost-effective and efficient solution in the long run.
