Reliable air conditioning is a must-have during the hot and humid Maryland summer season. When a system’s compressor malfunctions or fails, immediate repair or replacement is virtually always necessary.
The compressor is the heart of every air conditioning system — without this component, chemical refrigerant does not correctly circulate and absorb heat and excess moisture from indoor air.
S&L Air Conditioning and Heating, Upper Marlboro’s AC repair professionals, provide the following information about what to expect from an AC compressor repair service.
Understanding AC Compressor Repair
The compressor in your air conditioning system uses a motor to compress and pressurize refrigerant and then circulate it through a closed circuit of lines and coils. Refrigerants must be properly pressurized and moved through condenser coils to absorb heat and moisture from your indoor living space.
Compressors can fail due to various faults, including electrical issues, refrigerant leaks, or complete compressor failure. A professional HVAC technician begins the repair or replacement process by carefully diagnosing the precise issues affecting performance.
Inspection, Diagnosis, and Decision-Making
When you call in an expert HVAC technician, they assess your cooling system to pinpoint the root causes of poor performance or compressor malfunction.
Some of the common symptoms of a failing compressor include:
- Poor or nonexistent cooling
- Frequent cycling on and off without affecting indoor temperature
- Unusual noises
- Chemical or burning odors
A qualified technician uses advanced diagnostic technology and expertise to test different components. This process is critical because issues like capacitor problems, electrical faults, or refrigerant leaks can produce many of the same symptoms as a failing compressor.
After assessing your cooling system, you should expect a detailed cost estimate from your technician to effect repairs. AC compressor repair or replacement can be quite expensive, depending on the type of compressor, labor rates, and the overall age of your air conditioning units.
In newer systems, the cost of repairs could justify the expense, given the expected remaining lifespan of AC units with several years of service. However, the compressor replacement cost could be a better option with older systems.
Additionally, if your HVAC is over 10 or 15 years old, investing in a new unit rather than replacing the compressor could be more practical. At that age, other components are likely to begin failing because of ordinary wear and tear.
Purchasing a new unit provides multiple benefits, including increased energy efficiency, superior indoor air quality and cooling power, and a newly minted manufacturer’s warranty.
The AC Compressor Repair Process
If you decide to move forward with AC compressor repair, here’s what you can expect during the process.
Evacuation and Removal
The technician begins by completely evacuating all remaining refrigerant from the cooling system. This is essential to prevent environmental or system contamination.
The old compressor is carefully disconnected and removed. Depending on the nature of the repair and the parts and equipment needed, the technician may complete repairs on-site or at their workshop.
If the compressor is beyond repair or if you have decided to install a brand-new replacement compressor, the reinstallation process proceeds in a similar fashion.
Reinstallation
While the old compressor is out of the unit, the technician will look for any electrical issues that could have contributed to the failure.
The technician installs the repaired or replacement compressor with precise fitting and connections that match all manufacturer specifications and safety codes.
The technician recharges the entire cooling system with the correct amount of the proper type of chemical refrigerant. The technician also repairs any refrigerant leaks outside of the compressor unit.
The technician will inspect related components, including condenser coils and suction lines, for blockages or dirt buildup. Many times, the technician replaces other worn or damaged parts, like receiver driers, accumulators, or expansion valves.
Testing and Calibration
After reinstallation, the technician conducts rigorous system testing to check for proper refrigerant levels, proper pressures, and effective cooling. Calibration ensures the system is running correctly and properly responding to the thermostat before the technician completes the AC compressor repairs.
