Why Is My Air Conditioner Not Cooling?
If your air conditioner is running but not cooling your home, you’re not alone—it’s one of the most common AC issues homeowners face, especially during those intense summer months. At Integrity Air Solutions, we believe in helping you get to the bottom of the problem fast. Here are some likely reasons and what you can do about them:
Clogged Air Filter:
A dirty or clogged air filter restricts airflow, making it harder for your system to circulate cool air. If it’s been more than a month since you last changed the filter, start there. A clean filter can improve cooling and efficiency almost instantly.
Thermostat Issues:
Check that your thermostat is set to “cool” and the temperature is set correctly. Sometimes, dead batteries or incorrect settings can throw off the whole system.
Low Refrigerant Levels:
Refrigerant is the lifeblood of your AC system—it’s what absorbs heat and cools the air. If your AC is low on refrigerant, it might have a leak. This is not something you can fix with a quick DIY; call a pro to locate and repair the leak and recharge the system.
Dirty Condenser Coils:
The outdoor unit (condenser) needs to release heat effectively. If it’s covered in dirt, leaves, or debris, it can’t do its job. Carefully cleaning the coils or scheduling a maintenance visit can restore performance.
Frozen Evaporator Coil:
If airflow is restricted or there’s a refrigerant problem, the indoor coil can freeze—literally. A frozen coil means no cool air is making it into your home. Turn off your AC to let it thaw and call a technician to diagnose the cause.
Tripped Breaker or Faulty Capacitor:
Sometimes, the AC’s outdoor unit stops working due to electrical issues. If you hear the indoor fan running but no cooling is happening, the outdoor unit may not be powered. This could be a tripped breaker or a worn-out capacitor.
