During a recent service call in Las Vegas, our Fast Affordable Air team responded to a home experiencing uneven cooling. The homeowner reported that the air felt weak and inconsistent across different rooms. We dispatched a technician to perform a full system checkup on their Lennox central air conditioner.
Step-by-Step System Inspection
First, we checked the indoor temperature coming from the vent using an infrared thermometer. The supply air was blowing out at 53.2°F, which falls within a healthy cooling range. A normal supply air temperature typically falls between 50°F and 60°F when the system is working properly.
We then inspected the outdoor condenser unit—a crucial part of the cooling process. This Lennox condenser looked physically intact. We used a multimeter to check electrical voltage at the contactor and recorded a solid 123.1 volts. This confirms stable power input to the system.
Full System Review – Indoor and Outdoor
Up in the attic, we inspected the Lennox air handler and furnace. Everything appeared structurally sound, with sealed metal ductwork and properly strapped PVC condensate drain lines to route moisture safely out of the home.
We also evaluated the copper refrigerant lines. These lines carry the cooling fluid (often R-410A or Puron) between the indoor coil and the outdoor unit. They were properly insulated to prevent heat gain in the attic, which helps keep your energy bills lower.
Next, we inspected the gas line feeding the furnace. All joints were leak-free, with the shut-off valve accessible and secured. This gas line is responsible for powering the furnace during winter when heating is needed, making this a dual-function heating and cooling setup.
Lastly, we visually confirmed that both outdoor condensers were operating efficiently and that no refrigerant leaks or electrical corrosion were present. The condenser fan blades and coils were free of major debris or rust, which helps ensure strong airflow and good cooling performance.
