The compressor in your air conditioner circulates and pressurizes refrigerant, allowing it to absorb heat from indoors and release it outdoors, ensuring efficient cooling.

What is a Compressor?

A compressor is a crucial part of HVAC systems, including air conditioners and heat pumps. It works by pressurizing and circulating refrigerant, enabling it to absorb heat from indoors and release it outdoors, effectively cooling or, in heat pumps, heating your home.

How Does a Compressor Work?

In an HVAC system, refrigerant absorbs indoor heat, becoming a gas. The compressor pressurizes this gas, raising its temperature and converting it into a high-pressure gas. The refrigerant then moves to the condenser coil, releasing heat to the outside and resuming its cooling cycle. This process is essential for temperature regulation within your home.

Signs of a Failing Compressor

Over time, compressors experience wear and may show signs of failure, such as:

• Unchanging indoor temperatures: The system struggles to maintain set temperatures.
• Warm or lukewarm air discharge: In cooling mode, lukewarm air may be released outside instead of hot air.
• Unusual noises: Sounds like banging, hissing, or screeching may signal a malfunction.
• Visible leaks: Any leaks around the unit, potentially indicating refrigerant issues.

Compressor Replacement: Things to Consider

If you suspect compressor issues, consult our HVAC technician. Consider the age of the unit, warranty status, and repair versus replacement costs. Compressors are expensive, and it might be more economical to replace the entire system if your unit is nearing the end of its lifespan.

Maintenance Tips for Compressors

Compressor maintenance should only be performed by professionals. However, homeowners can keep the surrounding area clear of obstructions and replace air filters regularly. During professional servicing, the technician will clean components like the condenser coil and check for any issues, helping to extend the compressor's lifespan up to 15 years.
