The capacitor in your HVAC system stores and releases energy to keep the motors running smoothly, such as those in the compressor or fan. This little component ensures your system runs efficiently and effectively. However, your HVAC capacitors might start to fail due to various factors, affecting the overall performance of your heating and cooling systems.
Keep reading as All Seasons Inc. delves into the signs and causes of HVAC capacitor failure as well as ways to address and prevent them.
Most Common Signs
Keep an eye out for irregular temperature fluctuations, unusual noises produced by the system or unexpected shutdowns. If any of these indicators become apparent, promptly consult an HVAC professional for a thorough assessment and necessary repairs.
Heat and Extreme Temperatures
Extreme temperatures can lead to capacitor stress and breakdown. Capacitors are sensitive to overheating, which can be prompted by factors such as sun exposure. This problem is particularly found in rooftop-installed air conditioners that can experience temperatures exceeding 150 degrees on hot summer days.
Additionally, electrical overheating may result from prolonged and intensive HVAC unit operation, often observed during the hottest summer days. To prevent overheating, consider raising the thermostat slightly during such high-temperature periods and implement energy-efficient measures like utilizing reflective blinds on east- and west-facing windows.
Power surges, including lightning strikes during summer thunderstorms, can overwhelm and damage an HVAC system’s electrical components. Even minor power fluctuations within the electrical grid, triggered by household appliances cycling on and off, can gradually deteriorate capacitors.
Moreover, power outages caused by thunderstorms can result in damaging power surges when the electricity is restored, negatively impacting HVAC capacitors. To prevent these risks, install an HVAC surge protector, as this will ensure the protection of your air conditioning system and its capacitors.
Wear and Tear
As capacitors age, their capacity to store and release energy diminishes gradually. While wear and tear are inevitable, early detection of failing capacitors can lead to straightforward and cost-effective repairs. However, if failing capacitors are left unattended and the air conditioner continues to operate, it can result in more severe and costly problems in the future.
Regular maintenance and inspections by HVAC professionals can help prevent issues with HVAC capacitors. These experts conduct necessary checks and repairs to keep your system in good condition.
If your capacitor malfunctions, prompt professional assistance is necessary. Look for an HVAC company that is equipped to identify the issue, replace the faulty capacitor and swiftly restore your HVAC system.
