Park Ridge AC Replacement Project – From Compressor Failure to a New Cooling System
Any Season Heating & Cooling, Inc. recently completed an air conditioning replacement
for a homeowner in Park Ridge, IL 60068. This is the completed second part
of the same HVAC project we documented during our original service and diagnostic visit.
During the first visit, the homeowner contacted us because the central air conditioner
was repeatedly tripping the electrical circuit breaker. Our technician
inspected the HVAC system and performed electrical testing on the outdoor condenser and compressor.
The testing confirmed that the existing compressor was grounded, or electrically shorted
to ground.
A grounded compressor is a major mechanical and electrical failure. After we explained the
diagnosis and discussed the available repair and replacement options with the homeowner,
the customer decided to replace the air conditioning equipment rather than invest in the
failed older compressor.
What We Found During the Original AC Diagnostic Visit
The original service call began with one of the more serious symptoms an air conditioning
system can experience: the breaker would trip whenever the cooling equipment attempted to run.
A repeatedly tripping breaker should never simply be reset over and over because the breaker
may be protecting the home and equipment from an electrical fault.
We inspected the indoor and outdoor portions of the HVAC system and then electrically tested
the compressor. Our diagnosis confirmed that the compressor windings had developed a short
to ground. This explained why the breaker continued to trip.
Why a Grounded Compressor Is a Serious AC Failure
The compressor is often described as the heart of a central air conditioning system because
it moves refrigerant through the refrigeration circuit between the indoor evaporator coil
and outdoor condenser.
Inside the compressor is an electric motor with insulated windings. When that insulation fails,
a winding can make electrical contact with the compressor housing. This condition is known as
a grounded compressor.
Once a compressor is confirmed to be grounded, replacing a capacitor or contactor will not correct
the underlying failure. Depending on the age and condition of the system, homeowners generally
need to choose between compressor replacement and replacement of the air conditioning equipment.
Why the Breaker Was Tripping
In this Park Ridge home, the grounded compressor created an electrical fault when the air conditioner
attempted to operate. The circuit breaker opened to protect the electrical circuit. After confirming
the compressor failure, we advised the homeowner of the findings rather than continuing to reset
the breaker or replace unrelated parts.
Homeowner Chose Complete Air Conditioning Replacement
After reviewing the condition of the existing system and discussing the available options,
the homeowner chose to move forward with an AC replacement in Park Ridge, IL.
The goal was to replace the failed cooling equipment with a properly matched modern air conditioning
system that could provide reliable cooling and operate with the newer R-454B refrigerant.
We returned to the Park Ridge property and completed the installation with a
new Trane 3.5-ton outdoor condenser and a
new indoor cased evaporator coil.
New Trane 3.5-Ton AC Condenser Installed in Park Ridge
The new outdoor unit installed for this project is a Trane 3.5-ton air conditioning condenser.
The completed installation can be seen in the new photographs taken after the job was finished.
The old outdoor condenser with the grounded compressor was removed, and the new Trane condenser
was positioned on the existing outdoor equipment pad. The unit was set carefully to provide a stable
installation and proper service access around the equipment.
Correct positioning of an outdoor condenser is important. The condenser needs sufficient airflow
around the coil so it can reject heat from the home efficiently. It also needs to remain accessible
for future inspection, cleaning, maintenance, and HVAC service.
Why Proper Condenser Installation Matters
Even high-quality HVAC equipment depends heavily on installation quality. Refrigerant piping,
electrical connections, airflow, drainage, equipment matching, evacuation, charging, and startup
procedures all contribute to how well a new air conditioning system performs.
Installing the equipment correctly helps provide dependable operation while reducing the possibility
of problems caused by poor airflow, moisture inside the refrigeration circuit, incorrect refrigerant
charge, or improper electrical connections.
New Cased Evaporator Coil Installed Above the Existing Furnace
The indoor portion of the project included installation of a brand-new cased evaporator coil.
As shown in the completed indoor photograph, the new coil cabinet is installed directly above the
existing Lennox furnace.
The furnace provides airflow through the HVAC system, while the evaporator coil performs the cooling
function when the air conditioner is operating. During cooling operation, warm indoor air passes
across the cold evaporator coil, allowing heat to be absorbed by the refrigerant before the conditioned
air is delivered back into the home.
Matching the Indoor Coil With the Outdoor Condenser
Replacing an outdoor condenser is not simply a matter of connecting any outdoor unit to an existing
indoor coil. Equipment compatibility is important for refrigerant operation, cooling capacity,
efficiency, airflow, reliability, and manufacturer requirements.
For this project, the indoor cooling coil was replaced as part of the new AC installation so the
cooling system could operate as a properly configured system.
Indoor Installation Details
The completed indoor installation includes the new cased coil above the existing furnace,
refrigerant piping connections, condensate drainage, and the required transition between the
furnace and cooling coil cabinet.
R-454B Refrigerant Used in the New Air Conditioning System
This new Trane air conditioning system uses R-454B refrigerant. R-454B is one of the
newer lower-global-warming-potential refrigerants being used in residential air conditioning
equipment as the HVAC industry transitions away from older refrigerants.
New R-454B equipment is specifically engineered for this refrigerant and includes manufacturer
requirements and safety provisions appropriate for an A2L refrigerant system.
HVAC technicians working with R-454B systems need to follow the equipment manufacturer’s procedures,
use appropriate service practices, and ensure the refrigeration system is properly prepared,
evacuated, charged, and tested.
Why Refrigerant Type Matters During AC Replacement
Refrigerant is not interchangeable simply because two systems provide air conditioning.
The condenser, evaporator coil, metering components, controls, and other parts of the system must
be designed and approved for the refrigerant being used.
This is another reason homeowners should have new HVAC equipment installed by a knowledgeable
contractor familiar with current air conditioning systems and refrigerants.
Our AC Replacement Process for This Park Ridge Home
The completed project involved several important stages, beginning with the original diagnosis
and continuing through installation and final system testing.
1. Confirmed the Existing Compressor Failure
During our original visit, electrical testing confirmed that the old compressor was grounded.
This provided a clear explanation for the repeated breaker trips and allowed us to make a
recommendation based on an actual diagnosis.
2. Removed the Failed Outdoor Condenser
The old condenser was disconnected and removed so the replacement equipment could be installed.
3. Installed the New Cased Evaporator Coil
The existing indoor cooling coil was replaced with a new cased evaporator coil installed above
the furnace.
4. Installed the New Trane 3.5-Ton Condenser
The new Trane outdoor air conditioning condenser was placed on the outdoor equipment pad
and connected to the system.
5. Completed Refrigerant and Electrical Connections
The refrigeration circuit and electrical connections were completed as required for the new system.
Proper HVAC installation requires careful attention to refrigerant piping, electrical supply,
controls, airflow, drainage, and equipment configuration.
6. Evacuated and Prepared the Refrigeration System
The refrigeration system was properly prepared before operation. Removing air and moisture from
the refrigerant circuit is an essential part of professional AC installation because contaminants
inside the system can affect reliability and performance.
7. Started and Tested the New AC System
After installation was complete, we started the new air conditioning system and checked its operation.
The system is currently running properly with no issues and providing cooling for the home.
Completed AC Installation – System Running Great
The most important part of any HVAC replacement is the final result. After installation and startup,
the new system operated properly and the previous electrical problem associated with the failed
compressor was no longer preventing the home from having dependable air conditioning.
The homeowner was very happy with the completed installation, and the new Trane system is now
providing reliable cooling.
These after-installation photographs show the completed outdoor condenser and the new indoor
cased evaporator coil installed above the existing furnace.
Before and After: One Park Ridge HVAC Project From Diagnosis to Completion
This project is a useful example of why accurate HVAC diagnostics matter. On the first visit,
the customer did not simply need an air conditioner that was “not cooling.” The system was
repeatedly tripping the circuit breaker, which indicated that further electrical testing
was necessary.
Rather than guessing at the cause, we tested the system and confirmed a grounded compressor.
The homeowner could then make an informed decision about whether to repair the compressor
or replace the air conditioning equipment.
The customer selected replacement, and this follow-up article documents the finished project:
a new Trane 3.5-ton condenser, a new cased evaporator coil,
and a new R-454B air conditioning system.

Signs You May Need AC Repair or AC Replacement
Not every air conditioning problem requires replacement. Many systems can be repaired when the
cause is a capacitor, contactor, thermostat, wiring problem, fan motor, drain issue, or another
serviceable component.
However, homeowners should arrange professional service when they experience problems such as
repeated circuit breaker trips, an outdoor condenser that will not start, warm air from the vents,
unusual compressor noises, poor cooling performance, frequent breakdowns, or an older system
experiencing a major component failure.
Do Not Continue Resetting a Breaker That Keeps Tripping
If an AC breaker trips repeatedly, do not continue resetting it and forcing the air conditioner
to operate. There may be an electrical or mechanical problem that requires professional diagnosis.
In this case, the breaker was an important symptom that led us to discover the grounded compressor.
