During this air conditioning repair project, the technician inspected the outdoor central AC unit, checked the electrical parts, tested the refrigerant pressure, and verified cooling performance. The work focused on important HVAC parts like the run capacitors, condenser fan, compressor circuit, and refrigerant system.

Checking the Run Capacitors
The first photos show several capacitors removed or inspected during the repair. A capacitor is a small electrical part that helps a motor start and keep running. In simple terms, it gives the motor a quick push of power. Without the right capacitor, the fan motor or compressor may struggle, hum, overheat, or stop working.
One capacitor was rated at 7.5 microfarads, marked as 7.5µF and 370VAC. Another was rated at 10 microfarads, marked as 10µF and 370VAC. These smaller run capacitors are commonly used for motors, such as a condenser fan motor or blower motor, depending on the system design.
The photos also show a Titan Pro motor run capacitor rated at 5 MFD and 440/370VAC. MFD means microfarad, which is the measurement of how much electrical charge the capacitor can hold. The voltage rating shows the highest voltage the part is built to handle safely.
Another capacitor visible in the outdoor unit appears to be a 35/5µF dual-run capacitor. A dual-run capacitor helps two parts at the same time, usually the compressor and the condenser fan motor. The larger number, 35µF, is commonly for the compressor side. The smaller number, 5µF, is commonly for the fan side.
Why Capacitor Testing Matters
A weak capacitor can make an air conditioner act like it has a bigger problem. The outdoor fan may not spin correctly. The compressor may have a hard time starting. The central Cooling system may blow warm air. Sometimes the AC may run for a short time and then shut off because parts are getting too hot.
Replacing a bad or weak capacitor can help the Air Conditioning system run smoother. It can also protect the motor and compressor from extra stress. This is important because the compressor is one of the most expensive parts of a central Air Conditioner.
Refrigerant Pressure Check
The technician also connected refrigerant gauges to the outdoor condenser. The blue gauge reads the low side of the system, and the red gauge reads the high side. These readings help the technician understand how the refrigerant is moving through the Air Conditioner.
Refrigerant is the cooling chemical inside the system. It moves heat from inside the home to the outdoor unit. If the pressure is too low or too high, the HVAC system may not cool correctly. Pressure readings can point to problems like low refrigerant, airflow issues, a dirty coil, a restriction, or other system concerns.
In the photos, the gauges are connected while the condenser fan area is being checked. The outdoor fan is important because it pulls air across the condenser coil. The condenser coil is the metal coil around the outside unit. It releases heat outside so the home can feel cooler inside.
Temperature and Electrical Diagnostics
The technician also used a Fieldpiece meter during the repair. A meter is used to check electrical readings and temperature readings. In one photo, the display shows a low temperature reading around 30.24°F. Temperature checks help confirm how the cooling system is performing during service.
Electrical diagnostics are important because an AC system uses high voltage power. A technician checks parts carefully to make sure the system is running safely. This can include testing capacitors, checking wiring, inspecting terminals, and making sure the motor and compressor are receiving proper power.
Outdoor Condenser Inspection
The outdoor condenser was also inspected near the fan guard and service panel area. The condenser is the outside part of the Heating and Cooling system. It contains the fan, condenser coil, electrical controls, compressor, and refrigerant connections.
When the condenser is not working correctly, the central AC may not be able to remove heat from the home. That can lead to weak cooling, longer run times, higher power use, and uncomfortable indoor temperatures.
Benefits of This Air Conditioning Repair
This type of AC repair helps restore proper operation by checking the parts that commonly cause cooling problems. Capacitor replacement can help motors start and run correctly. Pressure testing helps confirm whether the refrigerant system is working in a safe range. Temperature testing helps show whether the Air Conditioning system is actually producing cool air.
For homes in Las Vegas, Henderson, North Las Vegas, and surrounding Clark County areas, this kind of repair is especially important because Cooling systems work hard during hot weather. A small part like a weak capacitor can stop the whole system from cooling. Finding the issue early can help reduce stress on the compressor and fan motor.
