This air conditioning repair project focused on checking the indoor HVAC system in the attic, inspecting the blower wheel, testing electrical parts, and reading refrigerant pressure at the outdoor central AC unit. For homes in Las Vegas, Henderson, North Las Vegas, and nearby Clark County areas, this kind of service is important because the cooling system works hard during hot weather.
The equipment shown includes an attic-installed Lennox gas furnace and air handler section connected to insulated ductwork. The outdoor Air Conditioner was also tested with refrigerant gauges and electrical meters. This helped the technician see how the system was moving air, using power, and cooling the home.

Attic HVAC System Inspection
The repair started in the attic, where the indoor furnace and air handler were located. An air handler is the indoor part of the HVAC system that moves air through the home. It contains the blower motor, blower wheel, electrical controls, and sometimes the evaporator coil area depending on the system design.
The access panels were removed so the technician could look inside the unit. The wiring, control board, blower motor area, gas line, and duct connections were checked. This step matters because a central Air Conditioning system can have cooling problems even when the outdoor unit is running. If the indoor blower is weak, dirty, or not receiving the correct electrical signal, the AC may not push enough cool air through the vents.
Blower Wheel and Airflow Check
One picture shows a close-up view inside the blower wheel. The blower wheel is the round fan part that spins and pushes air through the duct system. A simple example is like a hamster wheel, but instead of carrying a hamster, it moves air.
When the blower wheel gets dusty or the motor is weak, the Air Conditioner may still turn on, but the home may not cool well. Poor airflow can also cause the evaporator coil to get too cold. The evaporator coil is the cold indoor coil that removes heat from the air. If airflow is too low, the coil can freeze or the system can lose efficiency.
The attic ductwork was also checked. The pictures show flexible insulated ducts connected to the system. These ducts carry Central Cooling to the rooms. If a duct is loose, crushed, leaking, or poorly sealed, cooled air may escape into the attic instead of reaching the living space.
Electrical Testing With a Fieldpiece Meter
The technician used a Fieldpiece clamp meter to check electrical readings. A clamp meter is a tool that can measure electrical current by clamping around a wire. Current is often measured in amps. Think of amps like the amount of electricity flowing through the wire.
One reading showed about 7.15 amps during indoor system testing. Another outdoor reading showed about 2.46 amps. These readings help the technician understand whether motors and electrical parts are running within a normal range. If a motor pulls too many amps, it may be working too hard. If it pulls too little, it may not be running correctly.
The wiring and control components were also inspected. HVAC control boards are like the brain of the system. They help tell the blower, gas furnace, and cooling equipment when to turn on and off. Loose wires, weak connections, or a failing control part can cause short cycling, no cooling, or uneven indoor comfort.
Outdoor Refrigerant Pressure Test
At the outdoor central AC unit, the technician connected Yellow Jacket manifold gauges. Manifold gauges are tools used to measure refrigerant pressure inside an Air Conditioning system. Refrigerant is the special fluid inside the AC that carries heat out of the home.
The blue gauge reads the low-pressure side, and the red gauge reads the high-pressure side. These readings help show how the compressor, evaporator coil, condenser coil, and metering device are working together. The compressor is the part in the outdoor unit that pumps refrigerant through the system. The condenser coil is the outdoor coil that releases heat outside.
Checking refrigerant pressure is important because low refrigerant, airflow problems, a dirty coil, or a restriction can all affect cooling. A restriction means something is slowing or blocking refrigerant flow. A simple example is like a kink in a garden hose. The water may still move, but not the way it should.
Why This Repair Helps Indoor Comfort
This type of Air Conditioning repair helps find problems that are not always obvious. A homeowner may only notice that the house feels warm, some rooms are uncomfortable, or the system runs too long. But the real issue may be inside the attic unit, in the blower section, at the ducts, or in the refrigerant circuit outside.
By checking both the indoor and outdoor parts of the HVAC system, the technician can get a better picture of the full Heating and Cooling system. The indoor inspection helps confirm that air is moving properly. The electrical test helps confirm that motors and parts are using power correctly. The refrigerant pressure test helps confirm that the cooling cycle is operating as it should.
Energy Savings and System Protection
A clean and properly tested Central Air Conditioner can cool the home with less strain. When airflow is poor or electrical parts are weak, the system may run longer to reach the thermostat setting. Longer run time can raise energy bills and wear out parts faster.
Finding small issues early can help protect the blower motor, compressor, control board, and other major components. In the Las Vegas heat, this matters because the AC may run for many hours each day. A proper repair and diagnostic check can help improve comfort, support better airflow, and reduce stress on the cooling system.
Project Summary
This project included attic furnace and air handler inspection, blower wheel review, ductwork check, electrical testing with a Fieldpiece clamp meter, and refrigerant pressure testing with Yellow Jacket gauges. The visible equipment included a Lennox attic unit, insulated duct connections, indoor wiring, blower components, and the outdoor Air Conditioner.
