As summer approaches in Reno and Sparks, a properly functioning air conditioner becomes essential for staying comfortable. However, if your AC isn’t cooling, it can quickly turn into a frustrating situation. At Paramount Heating and Air Conditioning, we’ve helped many homeowners identify and resolve AC issues. Below, we’ll explain the most common reasons why your air conditioner may not be cooling and what you can do about it.
1. Dirty or Clogged Air Filters
Dirty filters restrict airflow, making your AC less efficient and unable to cool your home properly.
Signs of a Clogged Filter:
- Weak airflow from vents
- Dust buildup around registers
- Rising energy bills when the air conditioner is not cooling
Quick Fix:
Replace your air filter every one to three months. Homes with pets or allergies may need more frequent replacements.
2. Refrigerant Leaks
Refrigerant is crucial for cooling. Low refrigerant levels often indicate a leak, which reduces your system’s cooling ability.
Warning Signs:
- Warm air blowing from vents, signaling the air conditioner is not cooling
- Ice buildup on coils
- Hissing or bubbling sounds
Solution:
Contact a Reno HVAC professional to locate and repair the leak. They’ll also recharge the system with refrigerant.
3. Dirty Condenser Coils
The outdoor unit’s condenser coils release heat from your home. Dirt or debris on the coils reduces their efficiency.
What to Look For:
- Visible dirt or debris on the outdoor unit
- AC running longer than usual to cool, indicating an air conditioner not cooling properly
What to Do:
Turn off the system and gently clean the coils with a hose. Schedule professional cleaning for thorough maintenance.
4. Faulty Thermostat
A malfunctioning thermostat can prevent your air conditioner from cooling effectively.
Common Symptoms:
- Inaccurate temperature readings
- System failing to turn on or off, causing an air conditioner not to cool
How to Fix It:
Replace the thermostat batteries or upgrade to a smart thermostat for better control and efficiency.
5. Leaky or Poorly Insulated Ductwork
Leaky ducts allow cool air to escape, reducing efficiency and causing uneven cooling in your home.
Signs of Duct Problems:
- Certain rooms feeling warmer than others
- Higher energy bills due to the air conditioner not cooling efficiently
Next Steps:
Inspect ducts for visible leaks and seal them with mastic tape. Call a Sparks HVAC technician for major repairs.
6. Frozen Evaporator Coils
Frozen coils can’t absorb heat properly, which stops your AC from cooling.
What Causes Freezing:
- Low refrigerant levels leading to an air conditioner not cooling
- Restricted airflow
- Dirty air filters
How to Resolve It:
Turn off the AC to let the coils thaw. Replace the air filter and check for airflow issues.
