HVAC Compressor Struggling with Heat? Here Are 5 Signs That You Should Know

As the scorching temperatures of summer envelop us, the functionality of your commercial HVAC system becomes more critical than ever. Nothing can be more frustrating than experiencing cooling issues, leaving your co-workers, customers, or tenants sweltering in discomfort. With heatwaves becoming increasingly prevalent, and temperatures breaking records year after year, it is paramount to ensure that your HVAC system can withstand the relentless heat.

Commercial HVAC compressors find themselves at the frontline, battling against soaring external temperatures to maintain a cool indoor environment. Unlike refrigeration systems that primarily deal with waste heat, HVAC compressors are more susceptible to burnout due to the direct confrontation with ambient heat. Recognizing the warning signs of a struggling compressor can save you from sudden failures and emergency replacements. In this article, we will delve deeper into five crucial indicators that your commercial HVAC compressor might be losing the battle against the heat.

Inadequate Cooling

When your HVAC system is overworked, it sets off a chain reaction that can damage multiple components, including the condenser, and ultimately lead to compressor failure. Despite the air still blowing, your building may not be receiving the necessary cooling. Before suspecting the compressor, it’s vital to ensure that the refrigerant levels are adequate. Often, low refrigerant levels result from minor leaks. Once refrigerant issues are ruled out, inspect the air filters, and if they are not the culprit, the compressor may be at fault. Addressing this issue promptly can prevent further damage and maintain optimal cooling efficiency.

Rising Energy Consumption

While it is not unusual to witness a moderate increase in HVAC energy usage during the summer, substantial spikes in energy bills should not be overlooked. Inefficient HVAC components tend to work much harder to maintain the desired cooling levels, leading to higher energy consumption. To mitigate this, ensure that your smart thermostat’s sensors are clean and functioning correctly. Regular calibration of your thermostat can also contribute to significant savings on cooling costs, helping you beat the heat economically.

Continuous Cycling Or Continuous Cooling

A commercial HVAC system that struggles to reach the desired temperature may continuously run without ever achieving the target. This prolonged operation can lead to the condenser freezing over and further exacerbate compressor problems. Similarly, continuous cycling on and off, even when the target temperature is reached for brief periods, is an indication of compressor distress. Frequent power draw during cycling can escalate energy consumption and be detrimental to the compressor’s health.

Tripped Breakers And Blown Fuses

The occurrence of tripped breakers or blown fuses may indicate underlying electrical issues within your wiring system. It is essential to conduct a root cause analysis to identify and resolve these electrical problems rather than simply opting to replace the compressor. Neglecting to address the underlying issues could result in premature failure of the new compressor, attributed to improper voltages and electrical glitches. To ensure the longevity of your new compressor, a thorough inspection and resolution of electrical concerns are necessary.

Unusual Vibration Or Noise

While it is normal for compressors to exhibit some vibration during startup, any unusual vibrations or noises should not be dismissed. Even compressors designed to minimize noise may still produce some level of vibration during operation. Familiarize yourself with your compressor’s standard startup behavior and be attentive to any deviations. If you observe any unusual vibrations or noises, it is essential to conduct maintenance reviews promptly. Ignoring such signs may lead to more significant issues over time and potentially compromise the overall HVAC system’s efficiency.

Conclusion

In the ongoing battle against rising temperatures, your commercial HVAC compressor assumes a pivotal role in maintaining a comfortable indoor environment. Identifying the warning signs of a struggling compressor can prevent sudden breakdowns and the inconvenience they entail. If you notice any of the aforementioned signs, indicating that your compressor is struggling to beat the heat, taking proactive steps to replace it with a remanufactured compressor can be a cost-effective and timely solution. Ensuring that your commercial HVAC system is well-prepared to handle the heat will keep you and your occupants cool and content throughout the hottest months of the year. Don’t let the scorching temperatures overpower your HVAC system; instead, equip it to conquer the heat with ease.
