When your home starts feeling warm even with the AC running, it’s time to investigate. Fast Affordable Air was recently called to inspect and restore comfort to a residence in Las Vegas. The customer reported poor cooling throughout the home, and our HVAC technician got straight to work checking both indoor and outdoor system components.
Step 1: Checking the Return and Supply Temperatures
To start, we used an infrared thermometer to measure the air temperature at the return grille. The reading showed 78.0°F, which is the warm air being pulled into the system from inside the house (Image 1).
We then measured the supply air coming from a ceiling vent. The reading was 68.0°F (Image 4). That gives us a temperature drop of about 10 degrees. While this indicates the system is cooling, it’s borderline. Ideally, a healthy central air conditioning system should have a temperature split (difference between return and supply air) between 16°F and 22°F. A low split often points to issues like low refrigerant, dirty coils, or airflow restrictions.
Step 2: Inspecting the Indoor Coil and Airflow
Next, we accessed the indoor evaporator coil compartment. As seen in the image (Image 2), the copper refrigerant lines and coil itself appeared clear of major blockages or visible icing. This coil is essential because it absorbs heat from the air inside your home. If this coil becomes dirty or blocked, it drastically reduces system efficiency.
We also checked the air filter (Image 5) behind the return grille. Dirty filters are a common culprit in airflow problems. In this case, the filter was moderately clean and allowed proper air return into the system.
Step 3: Outdoor Unit Diagnostics – GREE Multi-Zone Condenser
Outdoors, we inspected the GREE central condenser unit (Image 3). This modern, multi-zone outdoor system uses inverter technology to adjust its speed based on demand, which saves energy and improves comfort. We verified that the dual fans were operational and that the coil was clean and unobstructed by debris or vegetation.
One of the benefits of using a GREE condenser is its quiet operation and energy-efficient performance, especially in hot climates like Las Vegas. The unit also features a compact design, which was perfect for the narrow installation area between the home and perimeter wall.
System Evaluation and Recommendations
After a full inspection, the temperature split suggested the system was cooling but not optimally. We recommended the following:
- Check refrigerant charge levels to ensure proper cooling efficiency
- Deep clean the indoor evaporator coil and blower compartment for better airflow
- Replace the air filter regularly to avoid future restrictions
Fast Affordable Air performs thorough AC evaluations and repairs across Las Vegas, Henderson, and North Las Vegas. We specialize in restoring full comfort while helping homeowners save on energy bills by catching problems early.
We use advanced diagnostic tools like infrared thermometers, check internal coil condition, and inspect high-efficiency systems like this GREE condenser to ensure lasting repairs. When systems fall out of spec, we tune them up to bring indoor comfort back in line.
