Why is My AC Running But Not Cooling Enough in Whitney, NV? Low Refrigerant & More

When your air conditioner is running but not cooling your home, it can be both frustrating and uncomfortable, especially in the middle of a hot summer. There are several potential reasons why your AC might not be doing its job effectively. Some issues are simple to fix, while others require professional attention. Today, we at LV Heating & Cooling would like to list the top reasons your AC isn’t cooling properly.

Dirty Air Filters

One of the most common reasons for poor cooling is a dirty or clogged air filter. Over time, filters collect dust, pet hair, and other debris, restricting airflow. This not only causes your AC to work harder but also reduces its ability to cool your home efficiently. Replacing or cleaning your air filter every 1–3 months can make a significant difference.

Low Refrigerant Levels

Refrigerant is essential for absorbing heat from the air inside your home. If your system is low on refrigerant, it won’t be able to cool effectively. Low levels usually indicate a leak, which should be handled by a licensed HVAC technician. Simply refilling the refrigerant without fixing the leak is only a temporary solution.

Thermostat Issues

Sometimes the problem isn’t with the AC unit itself but with the thermostat. If your thermostat isn’t working correctly, it may not signal the system to cool properly. Dead batteries, miscalibration, or outdated models can all lead to cooling issues. A quick thermostat check or upgrade to a smart thermostat might resolve the issue.

Dirty or Blocked Condenser Coils

Your outdoor condenser unit needs to release heat to the outside air, and it can’t do that efficiently if it’s dirty or blocked by leaves, dirt, or debris. When the condenser coils are dirty, your system may overheat or struggle to cool your home. Regular cleaning of the outdoor unit is essential to maintain performance.

Leaky or Blocked Ductwork

If your ductwork has leaks, holes, or blockages, cool air may be escaping before it reaches your living space. This not only reduces efficiency but also results in uneven cooling throughout the house. A professional duct inspection can identify and repair these issues.

Aging AC Unit

Most air conditioners have a lifespan of 10 to 15 years. As they age, their performance declines. If your system is over a decade old and struggling to cool your home, even after maintenance, it may be time to consider replacing it with a more efficient model.

Improper AC Size

If your AC unit is too small for your space, it will constantly run without ever achieving the desired temperature. On the flip side, an oversized unit will cool the air quickly but won’t dehumidify it properly, leaving your home feeling sticky and uncomfortable. A professional load calculation can ensure the right size for your home.
