AC Replacement in Park Ridge, IL After Diagnosing a Grounded Compressor
When an air conditioning system repeatedly trips a circuit breaker, it should never be ignored. A homeowner in Park Ridge, IL 60068 recently contacted Any Season Heating & Cooling, Inc. because their central air conditioning system was no longer operating properly. Every time the cooling system attempted to run, the electrical breaker would trip.
Our HVAC technicians inspected the complete heating and cooling system, including the indoor furnace, evaporator coil, electrical components, refrigerant system, and outdoor condenser. After performing electrical testing on the compressor, we confirmed that the AC compressor was grounded.
Because the compressor had experienced a major electrical failure and the existing air conditioner was no longer a practical candidate for repair, the homeowner decided to replace the air conditioning unit rather than invest in an expensive compressor replacement.
Customer’s Air Conditioner Kept Tripping the Breaker
One of the main symptoms reported by the homeowner was a circuit breaker that continued to trip when the air conditioner attempted to start.
A breaker that trips repeatedly is doing its job by protecting the home’s electrical system. Simply resetting the breaker over and over is not a proper solution because there may be an electrical short, damaged component, failing motor, compressor problem, or another potentially serious issue inside the HVAC system.
If your air conditioner is repeatedly tripping the breaker, it is best to turn the system off and have a qualified HVAC contractor near you inspect it before attempting to operate it again.
Our HVAC Diagnostic Process in Park Ridge
Before recommending replacement, we carefully inspected and tested the system to determine what was causing the electrical problem.
The indoor equipment includes a gas furnace with an evaporator coil mounted above it. The evaporator coil is part of the central air conditioning system and works together with the outdoor condenser to remove heat from inside the home.
Outside the home, we inspected the existing condenser and performed electrical testing on the compressor. Our testing confirmed that the compressor was shorted to ground, commonly referred to as a grounded compressor.
What Is a Grounded AC Compressor?
The compressor is one of the most important components in a central air conditioning system. It circulates refrigerant between the indoor evaporator coil and the outdoor condenser coil, allowing the system to absorb heat indoors and release that heat outdoors.
Inside the compressor is an electric motor containing windings. Under normal conditions, those windings remain electrically isolated from the metal body of the compressor.
When the electrical insulation surrounding the compressor windings fails, electricity can make contact with the compressor housing. This condition is commonly called a grounded compressor.
A grounded compressor can create excessive electrical current and cause the air conditioning breaker to trip almost immediately when the system attempts to start.
Why Does an AC Compressor Become Grounded?
There are several possible reasons a compressor can experience an internal electrical failure. Age and normal wear are common factors, but compressor damage can also result from overheating, electrical problems, improper refrigerant conditions, restricted airflow, dirty condenser coils, repeated hard starting, or other mechanical problems.
Once a compressor is confirmed to be internally grounded, it generally cannot be repaired internally. The compressor itself must be replaced, or depending on the age, efficiency, refrigerant type, and overall condition of the equipment, replacing the complete outdoor air conditioning unit may be the more practical option.
Compressor Replacement vs. Complete AC Replacement
Replacing only a compressor can sometimes make sense on a relatively new air conditioning system. However, the compressor is one of the most expensive components of an outdoor condenser.
When an older system experiences a major compressor failure, homeowners should compare the cost of compressor replacement with the cost and long-term benefits of installing newer HVAC equipment.
In this Park Ridge project, after discussing the condition of the existing equipment and the available options, the homeowner decided that air conditioner replacement was the better investment.
The existing outdoor condenser shown in these photographs will be replaced with new equipment. After installation, we will properly connect the refrigerant lines, electrical system, condensate components, indoor evaporator coil, and outdoor condenser as required for the new system.
Indoor Furnace and Evaporator Coil Inspection
The first photograph shows the home’s indoor HVAC equipment. The lower section is the gas furnace, while the cabinet directly above the furnace contains the air conditioning evaporator coil.
During an AC replacement, it is important not to look only at the outdoor condenser. The indoor coil, furnace blower, ductwork, refrigerant piping, drain system, electrical components, thermostat, and airflow should also be evaluated.
An air conditioning system operates as one complete system. Proper equipment matching and correct airflow are extremely important for cooling performance, efficiency, humidity control, and equipment life.
Outdoor AC Condenser Replacement in Park Ridge, IL
The other photographs show the existing outdoor condenser at the Park Ridge property before replacement.
The condenser contains several important components, including the compressor, condenser coil, condenser fan motor, capacitor, contactor, electrical controls, and refrigerant connections.
Because the compressor in this unit tested grounded, the existing condenser could no longer operate safely and reliably.
The homeowner approved replacement of the air conditioning system, and we will update this project with photographs of the completed installation.
Choosing the Correct Replacement Air Conditioner
Choosing a replacement air conditioner involves more than selecting a brand or matching the physical size of the old condenser.
A professional HVAC contractor in Park Ridge, IL should consider the cooling requirements of the home, equipment capacity, indoor and outdoor equipment compatibility, airflow, electrical requirements, refrigerant type, efficiency rating, ductwork condition, and manufacturer specifications.
Depending on the application, homeowners may consider equipment from manufacturers such as Trane and other recognized HVAC brands. The most important factor is selecting properly matched equipment and having it installed according to manufacturer requirements and accepted HVAC practices.
Signs Your AC Compressor May Be Failing
A failing compressor does not always fail without warning. Homeowners may notice symptoms such as the air conditioner not starting, warm air coming from the vents, unusual noises from the outdoor unit, the condenser attempting to start and stopping, reduced cooling capacity, unusually high electrical consumption, or a breaker that repeatedly trips.
These symptoms do not automatically mean the compressor is bad. Capacitors, contactors, wiring, fan motors, low-voltage controls, refrigerant problems, and other components can create similar symptoms. Proper electrical and HVAC testing is necessary before condemning a compressor.
Do Not Keep Resetting a Tripping AC Breaker
If your air conditioner trips its circuit breaker once, there may be several possible explanations. If it continues tripping, however, repeatedly resetting it can create additional equipment damage and may create an electrical safety concern.
Turn the cooling system off and contact a qualified HVAC professional who can determine why the breaker is opening.
In this Park Ridge home, diagnostic testing allowed us to identify the actual problem instead of guessing and replacing unnecessary components.
