AC Compressor Noise: Troubleshooting And Solutions

Hello Pembaca today.rujukannews.com! Whether you’re seeking refuge from the scorching summer heat or simply maintaining a comfortable indoor environment, your air conditioning (AC) system is a vital appliance. However, when your AC unit begins to make unusual noises, it can quickly turn a sanctuary of coolness into a source of frustration. One of the most common culprits behind these unwelcome sounds is the AC compressor. This article delves into the various types of noises an AC compressor can produce, the underlying causes, and practical solutions to diagnose and address the issues.

Understanding the AC Compressor’s Role 24 Hour Ac Company Hvac Fix Near Me Commercial Hvac Service Near Me Weekend Ac Repair Ac Fixing

The AC compressor is the heart of your cooling system. It acts as a pump, compressing the refrigerant gas, which is crucial for the entire cooling cycle. The compression process increases the refrigerant’s pressure and temperature. This high-pressure, high-temperature refrigerant then flows to the condenser, where it releases heat, transforming into a liquid. The liquid refrigerant then passes through an expansion valve, which lowers its pressure and temperature. Finally, it enters the evaporator coil, where it absorbs heat from the air, cooling your home. The cooled refrigerant then returns to the compressor to repeat the cycle.
